The system implements a complete voice pipeline that captures audio from microphones, detects when speech is occurring, transcribes the speech to text, and can automatically inject the transcribed text into active applications. - -## Requirements - -### Requirement 1 - -**User Story:** As a user, I want the system to capture audio from my microphone in real-time, so that I can provide voice input for transcription. - -#### Acceptance Criteria - -1. WHEN the application starts THEN the system SHALL initialize audio capture from the default or specified microphone device -2. WHEN audio capture is active THEN the system SHALL continuously capture audio at 16 kHz, 16-bit mono format -3. WHEN multiple audio devices are available THEN the system SHALL allow device selection via command-line arguments or environment variables -4. WHEN the specified audio device is unavailable THEN the system SHALL fall back to the default device and log the fallback -5. WHEN audio capture encounters errors THEN the system SHALL attempt automatic recovery with watchdog monitoring -6. WHEN no audio data is received for 5 seconds THEN the system SHALL trigger watchdog recovery and restart the audio stream - -### Requirement 2 - -**User Story:** As a user, I want the system to detect when I'm speaking versus when there's silence, so that transcription only occurs during actual speech. - -#### Acceptance Criteria - -1. WHEN audio frames are received THEN the system SHALL process them through voice activity detection (VAD) -2. WHEN speech is detected THEN the system SHALL emit a SpeechStart event -3. WHEN speech ends THEN the system SHALL emit a SpeechEnd event after minimum silence duration -4. WHEN using Silero VAD THEN the system SHALL use a default threshold of 0.3 for speech detection -5. WHEN using energy-based VAD THEN the system SHALL fall back to Level3 energy detection as a backup option -6. WHEN speech duration is less than 250ms THEN the system SHALL ignore the speech event as too short -7.

Domain-based splits > fix/feature splits for large refactors +- Graphite works best with path-based hunk assignment +- Review efficiency scales with domain ownership +- Merge conflicts correlate with crate edit frequency + +### About the Tools +- `gt split --by-hunk` is powerful but requires clear mental model +- Path patterns make split decisions obvious +- `gt reorder` fixes ordering mistakes easily +- `gt sync` handles post-merge rebases automatically + +--- + +## Confidence Level + +**High Confidence (95%)** + +**Evidence:** +- Repository structure analyzed (CLAUDE.md, crate layout) +-

Use them to adapt settings for staging, production, or CI environments. - -### Key Principles -- **Precedence**: CLI flags > Env vars > `config/default.toml` > defaults. -- **Security**: Store secrets (e.g., API keys) in env vars or secret managers; never in TOML. -- **Nesting**: Use `__` for sections, e.g., `COLDVOX_STT__PREFERRED=vosk` overrides `[stt].preferred`. - -### Examples in Deployment Contexts -- **CI/CD (GitHub Actions)**: Set in workflow `.env` or job steps: - ```yaml - env: - COLDVOX_STT__PREFERRED: vosk # Use local model in CI - COLDVOX_INJECTION__FAIL_FAST: true # Fail fast in tests - ``` - Validate in workflows: See [docs/self-hosted-runner-complete-setup.md](docs/self-hosted-runner-complete-setup.md) for integration. - -- **Systemd Service** (e.g., `/etc/systemd/system/coldvox.service`): - ``` - [Service] - ExecStart=/opt/coldvox/coldvox-app - Environment="COLDVOX_DEVICE=default" - Environment="COLDVOX_STT__LANGUAGE=en" - EnvironmentFile=/etc/coldvox/prod.env # For bulk secrets - ``` - -- **Docker/Kubernetes**: - - Docker: `docker run -e COLDVOX_INJECTION__INJECTION_MODE=paste -e COLDVOX_STT__MAX_MEM_MB=2048 coldvox-image` - - K8s: Use ConfigMap for non-secrets, Secret for sensitive vars like `COLDVOX_STT__API_KEY`. - -- **Rollback**: If env overrides cause issues, unset vars and restart; fallback to `default.toml`. - -For comprehensive deployment steps, including validation and rollback with these vars, refer to [docs/deployment.md](docs/deployment.md). Additional VAD flags (e.g., `COLDVOX_VAD__SENSITIVITY`) follow the same pattern; extend as needed in code. +# ColdVox Configuration & Runtime Controls + +The current application relies on a layered configuration system: + +1. **`config/default.toml`** – committed defaults. +2. **Environment variables** – override any key using the `COLDVOX_` prefix and `__` for nested tables. +3. **Command-line flags** – limited to a few operational toggles. + +## Command-line Flags + +| Flag | Description | Notes | +| --- | --- | --- | +| `--list-devices` | Enumerate input devices via CPAL and exit. | Useful for discovering the value to set via `COLDVOX_DEVICE`. | +| `--tui` | Launch the TUI dashboard on top of the shared runtime. | Keyboard shortcuts: `S` start, `A` toggle VAD/hotkey, `R` reset, `Q` quit. | +| `--injection-fail-fast` | Force the process to exit if all injection methods fail. | Mirrors `injection.fail_fast` in the config file. | + +Other behaviour is controlled through configuration or environment variables. + +## `config/default.toml` + +### Top-level keys + +| Key | Default | Purpose | +| --- | --- | --- | +| `resampler_quality` | `"balanced"` | Selects resampler quality (`fast`, `balanced`, `quality`). | +| `activation_mode` | `"vad"` | Chooses between VAD-driven (`vad`) and hotkey (`hotkey`) activation. | +| `enable_device_monitor` | `true` | Enables ALSA/PipeWire hotplug polling. | +| `device` | *(unset)* | Optional preferred input device; fallbacks are used when omitted. | + +### `[injection]` + +| Key | Default | Description | +| --- | --- | --- | +| `fail_fast` | `false` | Abort if all injection methods fail (same effect as CLI flag). | +| `allow_kdotool` / `allow_enigo` | `false` | Opt-in backends for KDE/X11 and cross-platform input. | +| `inject_on_unknown_focus` | `true` | Permit injection when focus cannot be determined. | +| `require_focus` | `false` | Require editable focus before injecting. | +| `max_total_latency_ms` | `800` | Total latency budget per injection attempt. | +| `per_method_timeout_ms` | `250` | Timeout per backend attempt. | +| `clipboard_restore_delay_ms` | `500` | Delay before restoring clipboard contents after paste. | +| `cooldown_*` settings | `10000`, `2.0`, `300000` | Failure cooldown initial value, backoff factor, and max cap. | +| `allowlist` / `blocklist` | `[]` | Regex (when compiled with `regex`) or substring filters for app IDs. | + +### `[stt]` + +| Key | Default | Description | +| --- | --- | --- | +| `preferred` | `null` | Preferred STT plugin ID (e.g., `"vosk"`). | +| `fallbacks` | `[]` | Ordered fallback plugin IDs. | +| `require_local` | `false` | Reject remote/cloud STT providers. | +| `max_mem_mb` | `null` | Optional memory ceiling for STT plugins. | +| `failover_threshold` / `failover_cooldown_secs` | `5` / `10` | Consecutive error threshold and cooldown before failover. | +| `model_ttl_secs` | `300` | Idle model lifetime before GC. | +| `disable_gc` | `false` | Disable model garbage collection. | +| `metrics_log_interval_secs` | `30` | Periodic STT metrics logging interval (0 disables). | +| `debug_dump_events` | `false` | Emit verbose transcription events to logs. | +| `auto_extract` | `true` | Allow automatic extraction of Vosk models from zip archives. | + +## Environment Overrides + +Use the `COLDVOX_` prefix, replacing dots with double underscores: + +- `COLDVOX_DEVICE="USB Microphone"` overrides the capture device. +- `COLDVOX_INJECTION__FAIL_FAST=true` mirrors the CLI flag. +- `COLDVOX_STT__PREFERRED=vosk` selects Vosk as the primary STT plugin. + +Boolean overrides accept common truthy values (`true`, `1`, `yes`).
