nc 61d5d540db Add --unduck-delay to keep music ducked after TTS 2026-10-15 13:47:27 +03:00
43a183a232 Add --music-output-device to route music separately from voice (#350)
* Add --music-output-device to route music separately from voice

Music/media and TTS both play through --audio-output-device today, with no
way to send them to different sinks. Add an optional --music-output-device
(env MUSIC_OUTPUT_DEVICE) that the music player uses instead, defaulting to
--audio-output-device so existing setups are unchanged. Wired through
docker-entrypoint.sh and documented in the README and install docs.

* docs: fix swapped Default/Description columns in env var table

The MIC_VOLUME, MIC_AUTO_GAIN, MIC_NOISE_SUPPRESSION and
AUDIO_INPUT_CHANNELS rows had their Default and Description columns
swapped relative to the table header; fix the ordering and the
'Suppresion' misspelling. Also repair the UNMUTE_SOUND row, whose
description was garbled and which was missing its closing table pipe.

SpiliosDmk 69a4fd3098 docs: add realtime scheduling tuning for constrained hardware (#376)
The core problem in #164 (config fully overriding pipewire.conf) was
already fixed by switching to pipewire.conf.d. This adds the
remaining performance-tuning recommendation (libpipewire-module-rt)
from the issue thread that never made it into the docs, to reduce
audio dropouts on hardware like the Raspberry Pi 3B.

Closes #164

# Linux Voice Assistant - AI Policy
We support using AI (i.e., LLMs) as tools when contributing to Linux Voice Assistant. However, you are responsible for any contributions you submit, and we are responsible for any contributions we merge and release. We hold a high bar for all contributions to our projects.
Our maintainers dedicate their time and expertise to reviewing contributions. Submitting AI-generated content that you have not personally reviewed and understood wastes that time and will not be accepted.
## Autonomous agents
We do not allow autonomous agents to be used for contributing to our projects. We will close any pull requests or issues that we believe were created autonomously, and may mark automated comments as spam. This includes contributions that bypass the provided issue or pull request templates.
## Communication on issues, pull requests, and code reviews
We don't mind if you use AI tools to help you write. However, do not have tools post unreviewed content on your behalf. Keep responses to the minimum needed to communicate your intent. We may hide any comments that we believe are unreviewed AI output.
If you are opening a pull request, we expect you to be able to explain the proposed changes in your own words. This includes the pull request description and responses to questions. If you use AI to help generate the pull request summary, you must review it for technical accuracy.
**Do not use AI to generate answers to questions from maintainers.** You should understand and be able to explain your own work. Using AI to improve grammar or clarity is fine, but the substance of your responses must be your own.
If you wish to include context from an interaction with AI in your comments, it must be in a quote block (e.g., using `>`) and disclosed as such. It must be accompanied by your own commentary explaining the relevance and implications of the context. Do not share long snippets.
## Non-native English speakers
We understand that AI is useful when communicating as a non-native English speaker. If you are using AI to translate your comments, please ensure the translation accurately reflects your intent. Including your original text in a details block shows the effort behind your contribution, helps maintainers verify the translation if needed, and keeps the conversation readable.
## Code and documentation contributions
AI can be a helpful tool for writing code and documentation. However, due to the foundational open source nature of our projects, we require a human in the loop who understands the work produced by AI.
All contributions must be reviewed and understood by the contributor before submission. You should be able to explain every change in a pull request you submit. Pull requests that appear to be unreviewed AI output will be closed without review.
## Our use of AI
Some of our projects use AI tools to assist with code reviews, issue triaging, reporting, and other project management tasks. These tools may leave comments on pull requests or issues. As with any automated tooling, these comments are not always correct.
If an AI tool leaves a comment on your contribution, treat it as you would any other review comment. If you believe it is incorrect, say so; a brief explanation is sufficient. Maintainers always have the final say. If in doubt, ask a maintainer.
## Enforcement
Contributions that do not follow this policy will be closed. Repeated violations may result in being blocked from contributing to LVA projects.

# Contributing to Linux Voice Assistant
Everybody is invited and welcome to contribute to Linux Voice Assistant. Even if you are not a developer, perhaps you would like to help with the documentation? If you are a developer and have a feature that isn't supported by LVA yet, why not spend some time and help to integrate it?
The process is straight-forward.
- Fork the LVA repository.
- Write the code for your feature or fix.
- Ensure tests pass and linting succeeds (`./script/lint` and `./script/tests`).
- Create a Pull Request against the `main` branch.
## Feature suggestions
If you want to suggest a new feature for LVA, please open a discussion on GitHub.
## Issue Tracker
If you want to report an issue, please create an issue on the repository.
## AI Policy
Linux Voice Assistant is an [Open Home Foundation](https://www.openhomefoundation.org/) project and follows the [OHF AI Policy](https://github.com/music-assistant/.github/blob/main/AI_POLICY.md). Please read it before submitting AI-assisted contributions. The TLDR: AI tools are allowed, but a human is responsible and must review and understand every change. Autonomous agents and unreviewed AI output will be rejected.

# PR Review Standards
## Review Philosophy
- Only comment when confident an issue exists
- Be concise: one sentence per comment when possible
- Focus on actionable feedback, not observations
- When reviewing text, only comment on clarity issues if the text is genuinely confusing or could lead to errors
## What to Analyze
Review all code changes for:
- Code quality and style consistency with the existing codebase
- Potential bugs or issues
- Performance implications
- Blocking IO in async code
- Security concerns
- Test coverage
- Documentation updates if needed
## Project Standards
Respect the project standards as outlined in AGENTS.md. Any deviations must be raised as `[PROBLEM]`.
Key standards for LVA:
- Python 3.11, 3.12, 3.13 supported
- Black formatting with 200 char line length
- isort import sorting with black profile
- mypy type checking with strict settings
- pylint code quality checks (many checks disabled in pyproject.toml)
## Architecture-Specific Checks
- `linux_voice_assistant/wake_word.py` - Wake word model loading is hardware-dependent, verify no assumptions about specific hardware
- `linux_voice_assistant/mpv_player.py` - Audio output requires `libmpv-dev`, check for proper error handling
- `linux_voice_assistant/webrtc.py` - Noise suppression/gain algorithms need careful review for audio quality
- `linux_voice_assistant/satellite.py` - ESPHome API protocol handling must be robust
## CI Context
Lint runs on Python 3.13, tests run on Python 3.12 with libmpv-dev.
### What CI Checks
- **Lint**: `.github/workflows/lint.yml` runs all linting checks
- **Tests**: `.github/workflows/tests.yml` runs pytest unit tests
## Skip These (Low Value)
Do not comment on:
- Style/formatting (pre-commit handles this)
- Test failures (CI catches this)
- Missing dependencies (CI catches this)
- Minor naming suggestions
- Suggestions to add comments
- Logging suggestions unless security-related
## Issue Categories
Categorize every issue as:
- `[CRITICAL]` — must fix before merging (bugs, security issues, broken functionality)
- `[PROBLEM]` — should fix (code quality, bad patterns, missing tests)
- `[SUGGESTION]` — optional improvement (style, minor refactors, nice-to-haves)
## PR Title
The PR title must be a functional description of the change. It must NOT contain conventional commit prefixes such as `feat:`, `fix:`, `refactor:`, `chore:`, etc. Labels categorize PRs, not the title. Flag as `[PROBLEM]` if the title uses such prefixes.

name: review-pr
description: Use when asked to review a GitHub pull request, PR link is shared, or user says /review-pr
# Review GitHub Pull Request
Review the GitHub pull request: $ARGUMENTS.
## Steps
1. Run `gh pr view` to get PR details and description.
2. Run `gh pr diff` to see all changes.
3. Compare the local commit hash with the remote PR head commit.
- Make sure to do your work in a git worktree to avoid affecting the checked out branch.
- If they don't match, run `gh pr checkout` to check out the PR locally.
- **HARD STOP**: If `gh pr checkout` fails for ANY reason, STOP immediately. Do NOT attempt workarounds. Alert about the failure and wait for instructions.
- After checkout, verify the local commit hash matches the remote one. If they still don't match, STOP.
4. Run `gh pr checks` to see CI status.
5. Apply the review standards defined in `REVIEW_STANDARDS.md` (same directory).
6. Output review feedback to the CONSOLE only. DO NOT act on GitHub (no posting comments, no approving, no requesting changes).
## Output Format
List specific comments per file/line that need attention. Do not list things that are already correct.
Each comment:
1. State the severity ([CRITICAL], [PROBLEM], [SUGGESTION])
2. State the problem (1 sentence)
3. Why it matters (1 sentence, if needed)
4. Suggested fix (snippet or specific action)
End with an overall assessment and summary:
```
Overall assessment: <approve | request changes | comment>
- [CRITICAL] <issue>
- [PROBLEM] <issue>
- [SUGGESTION] <improvement>
```
## Constraints
- DO NOT make any changes to the code.
- No need to run tests or linters, just review the code changes.

# Project Context for AI Agents
## Behaviour
- NEVER automatically reply on Github (PRs or Discussions) without explicit consent from the developer.
- Always run `./script/lint` and `./script/tests` after code changes to ensure standards are met.
## Project Overview
**Linux Voice Assistant (LVA)** - A Linux-based voice satellite software for Home Assistant using the ESPHome protocol.
### Purpose
- Provides voice control and interaction for Home Assistant via the Assist integration
- Runs on x64/ARM64 Linux hardware with PulseAudio/PipeWire audio support
- Performs local wake word detection (OpenWakeWord/MicroWakeWord) and on-device processing
### Architecture
- **Protocol**: ESPHome API via `aioesphomeapi` for Home Assistant integration
- **Wake Words**: Supports both OpenWakeWord and MicroWakeWord engines
- **Audio**: Uses `soundcard` library for input, `python-mpv` for output
- **Peripherals**: WebSocket API for LEDs, buttons, HAT boards
- **Discovery**: mDNS/ZeroConf for auto-discovery by Home Assistant
### Key Components
- `linux_voice_assistant/__main__.py` - Main entry point with CLI argument parsing
- `linux_voice_assistant/satellite.py` - VoiceSatelliteProtocol implementation (ESPHome API)
- `linux_voice_assistant/wake_word.py` - Wake word model loading and detection
- `linux_voice_assistant/webrtc.py` - WebRTC noise gain/NS processing
- `linux_voice_assistant/mpv_player.py` - MPV-based media player
- `linux_voice_assistant/entity.py` - Entity definitions (MediaPlayer, MuteSwitch, etc.)
- `linux_voice_assistant/api_server.py` - ESPHome API server
- `linux_voice_assistant/peripheral_api.py` - Peripheral WebSocket API server
- `linux_voice_assistant/models.py` - Preferences and ServerState dataclasses
## Development Commands
### Setup
```bash
./script/setup --dev # Install dev dependencies in virtual environment
```
### Linting
```bash
./script/lint # Run all linting checks
./script/lint_black # Black formatting check (add --auto to fix)
./script/lint_isort # isort import sorting check (add --auto to fix)
./script/lint_flake8 # flake8 style checks
./script/lint_mypy # mypy type checking
./script/lint_pylint # pylint code quality checks
```
### Testing
```bash
./script/tests # Run pytest unit tests
```
## Code Quality Standards
- **Python**: 3.11, 3.12, 3.13 supported
- **Formatting**: Black (200 char line length, py312/py312 target)
- **Import Sorting**: isort with black profile
- **Type Checking**: mypy with strict settings
- **Linting**: pylint (many checks disabled in pyproject.toml for practical reasons)
## Testing Strategy
- Unit tests in `tests/unit/` using pytest with asyncio mode
- Test helper `make_state()` in `tests/unit/conftest.py` for creating state fixtures
- Mocks used heavily for hardware dependencies (audio devices, MPV, wake words)
## CI/CD
- GitHub Actions for lint checks and unit tests
- Tests run on Python 3.12 with libmpv-dev system dependency
- Lint runs on Python 3.13
## Branching and PRs
- All PRs target `main` (primary development branch). `stable` is for production releases.
- PRs labeled `bugfix` + `backport-to-stable` are automatically backported to `stable` — use only for bugs also present in `stable`.
## Agent Commands
When making code changes, run these commands in order:
1. **Format code**: `./script/lint_black --auto` and `./script/lint_isort --auto`
2. **Run linting**: `./script/lint`
3. **Run tests**: `./script/tests`
## Code Style
### Comments
Only use comments to explain complex, multi-line blocks of code. Do not comment obvious operations. Inline comments are there to explain code parts that need explaining - keep them when editing code.
### Docstring Format
Use Sphinx-style docstrings with `:param:` syntax. For simple functions, a single-line docstring is fine. The docstring should provide clarity to the caller, not explain how it works technically.
```python
def my_function(param1: str, param2: int, param3: bool = False) -> str:
"""
Brief one-line description of the function.
:param param1: Description of what param1 is used for.
:param param2: Description of what param2 is used for.
:param param3: Description of what param3 is used for.
"""
```
Do **not** use Google-style (`Args:`) or bullet-style (`- param:`) docstrings.
### File structure
Private methods should be at the bottom of the file, public at the top.
## Verification Checklist
Before claiming completion:
- [ ] Ran `./script/lint` - all checks passed
- [ ] Ran `./script/tests` - all tests passed
- [ ] For audio-related changes: Note that hardware testing (microphone/speaker) was NOT performed
- [ ] Did NOT claim hardware behavior is verified unless actually exercised
- [ ] Changes are focused on one feature or fix per change
## Areas Requiring Extra Care
- `linux_voice_assistant/wake_word.py` - Wake word model loading is hardware-dependent
- `linux_voice_assistant/mpv_player.py` - Audio output requires `libmpv-dev`
- `linux_voice_assistant/webrtc.py` - Noise suppression/gain algorithms
- `linux_voice_assistant/satellite.py` - ESPHome API protocol handling

# Audio Options: Gain, Noise Suppression, and Wake Word Sensitivity
## What do Gain and Noise Suppression do
### Gain
When you change gain, LVA(using the [webrtc](https://github.com/OHF-Voice/webrtc-noise-gain) library) automatically adjusts the microphone input volume to keep it at a consistent level. If you're speaking quietly it boosts the signal, if you're speaking loudly it reduces it. Useful in the following ways:-
- Microphones that are too quiet by default
- Environments where you move around relative to the mic
- Keeping wake word detection consistent regardless of speaking volume
### Noise Suppression
When you change noise suppression, LVA(using the [webrtc](https://github.com/OHF-Voice/webrtc-noise-gain) library) filters out constant background noise from the audio signal. It works by learning what "silence" sounds like in your environment and subtracting that from the audio. Useful in the following ways:
- Noisy environments
- Improving STT accuracy by sending cleaner audio to Home Assistant
- Reducing false wake word triggers from background noise
## Using Gain and Noise Suppression with LVA
LVA implements gain and Noise Suppression in two ways:
- [CLI Argument/ENV file](#cli-argumentenv-file)
- [Home Assistant Entity](#home-assistant-entity)
### CLI Argument/ENV file
#### CLI Argument
Using docker-entrypoint.sh the following flags can be used to set gain and noise suppression:
- `--mic-auto-gain`(ranges from 0-31)
- `--mic-noise-suppression`(ranges from 0-4)
#### ENV file
You can add/edit these variables in the .env file to set gain and noise suppression:
- `MIC_AUTO_GAIN="0"`
- `MIC_NOISE_SUPPRESSION="0"`
### Home Assistant Entity
LVA exposes two slider entities to change these gain and noise suppression from which you can edit the gain and noise suppression at runtime.
💡 **Note:** Setting the flag and ENV values to 0 turns them off and are not used.
💡 **Note:** Keep in mind that when the flags are set they will overwrite the previous value in the preferences file and also they will be overridden if the value is changed in Home Assistant(Also applies to the ENV file but the ENV file will always overwrite the last value on startup).
## Wake Word Sensitivity
LVA exposes three numeric controls in the Home Assistant device page for fine-grained sensitivity tuning. These let you dial in the exact probability threshold that best matches your microphone quality, room acoustics, and false-activation tolerance.
| Entity | Description | Default |
|--------|-------------|---------|
| **Wake Word 1 Sensitivity** | Probability cutoff for the primary wake word | From model manifest |
| **Wake Word 2 Sensitivity** | Probability cutoff for the secondary wake word (if active) | From model manifest |
| **Stop Word Sensitivity** | Probability cutoff for the stop word | From model manifest |
Values range from `0.0` to `1.0`:
- **Higher value** (e.g. `0.95`) → more selective, fewer false activations, may miss quieter or accented speech
- **Lower value** (e.g. `0.50`) → more responsive, but more likely to trigger on similar-sounding words
The defaults are read directly from each model's `.json` manifest file (the `probability_cutoff` field), so bundled models like `okay_nabu` (0.85), `hey_jarvis` (0.97), and custom downloaded models all start at their author-tested baseline. Changes made in the Home Assistant UI are persisted in `preferences.json` and survive restarts.
**Tuning guide:**
- If the wake word **rarely activates** (misses your voice): lower the value slightly, e.g. by `0.05` steps
- If the wake word **activates too often** (false triggers from TV, music, or similar words): raise the value slightly
- Start from the model's default and make small adjustments — a change of `0.05–0.10` is usually enough to notice a difference
- Far-field microphones with noise cancellation (e.g. ReSpeaker, Satellite1) generally work well at the default values; basic USB microphones may need a lower threshold

# Dashboard / Home Assistant Entities
Once your satellite is connected, Home Assistant exposes a set of controls on its device page (via the ESPHome integration) that let you change LVA's behavior at runtime, without restarting the container or editing config files. This document walks through each of those entities.
> **Go to [Settings > Devices & services](https://my.home-assistant.io/redirect/integrations/) and select the ESPHome integration.**
![Device page overview](./images/overview.png)
## Wake Word
The device page exposes one or two wake word selects (**Wake Word 1**, **Wake Word 2**), depending on whether your assistant is configured for dual wake words. Changing the selection here takes effect immediately and is persisted to `preferences.json`, so it survives restarts.
![Wake word select](./images/wake_word.png)
💡 **Note:** Models suffixed with **(OWW)** in the dropdown are [openWakeWord](https://github.com/dscripka/openWakeWord) models; everything else is a [microWakeWord](https://github.com/kahrendt/microWakeWord) model. Both engines can be mixed and matched, but keep in mind:
- **microWakeWord** models are lighter-weight and use engine that can run on lower-end devices and are located in the `wakewords` directory.
- **openWakeWord** models use higher engine with more accuracy and are located in the `wakewords/openWakeWord` directory.
See the [Wake Word section](install_application.md#wake-word) of the installation guide for the full list of bundled models and how to add custom ones.
## Mute Switch
The **Mute** switch disables wake word detection and stops the assistant from responding to any wake word or button-triggered listening, without stopping the LVA process itself. While muted, a configurable sound plays to confirm the mute/unmute transition (`--mute-sound` / `--unmute-sound`).
![Mute Switch](./images/mute_switch.png)
## Thinking Sound
The **Thinking Sound** switch toggles whether a short audible chime plays while the assistant is processing your request (between the end of listening and the start of the response). This is the same setting as the `--enable-thinking-sound` CLI flag / `ENABLE_THINKING_SOUND` environment variable, but can be flipped on or off at runtime from this switch. The change is saved to `preferences.json`.
![Thinking Sound](./images/thinking_sound.png)
## Media Player
The **Media Player** entity controls playback (play/pause/stop) and volume for both:
- Music/media played through the satellite, and
- The assist pipeline itself (wake word chime, TTS responses, thinking/processing sound, etc.)
Both share a single volume control — there is no separate volume for the pipeline versus music playback. Adjusting the volume slider on this entity changes both at once, and the value is persisted to `preferences.json` so it's restored on the next startup.
![Media player entity](images/media_player.png)
## Microphone Settings
### Volume
Controls the microphone volume to adjust the area distance from which the microphone can pick up your voice. The volume slider is persisted to `preferences.json` so it's restored on the next startup.

| **Stop Word Sensitivity** ![alt text](./images/stop_word_sensitivity.png) | Probability cutoff for the stop word | From model manifest |
Values range from `0.0` to `1.0`:
- **Higher value** (e.g. `0.95`) → more selective, fewer false activations, may miss quieter or accented speech
- **Lower value** (e.g. `0.50`) → more responsive, but more likely to trigger on similar-sounding words

## Support
If a dashboard control doesn't behave as expected, enable `--debug` (or `ENABLE_DEBUG=1`) and check the logs — every change made from the Home Assistant device page is logged when it's received and persisted.

💡 **Note:** On constrained hardware like a Raspberry Pi 3B, audio
processing can be interrupted by other system activity, causing
audible glitches or dropped wake-word detections. Loading the
`libpipewire-module-rt` module raises PipeWire's scheduling priority
(`rt.prio`) above normal processes, which reduces these interruptions.
The `flags = [ ifexists nofail ]` ensures this configuration is
silently skipped rather than causing a startup failure on systems
where realtime scheduling isn't available (e.g. some containers or
restricted kernels).
Add the following content:
```
context.properties = {
default.clock.rate = 16000
}
context.modules = [
{ name = libpipewire-module-rt
args = {
nice.level = -11
rt.prio = 88
}
flags = [ ifexists nofail ]
}
