0.0.6 #

  • BREAKING CHANGE: Convert all VAD APIs to async Future-based methods for better async/await support
    • API: Convert startListening(), stopListening(), pauseListening(), and dispose() methods in VadHandlerBase to return Future<void>
    • Web: Update VadHandlerWeb implementation to use async method signatures
    • Non-Web: Update VadHandlerNonWeb implementation to use async method signatures and properly await internal async operations
    • Example: Update example app to use async/await pattern when calling VAD methods
  • introduce pauseListening feature
    • API: Add pauseListening() to VadHandlerBase.
    • Web: implement pauseListeningImpl() in vad_web.js and expose via JS bindings.
    • Non-Web: add _isPaused flag in VadHandlerNonWeb; ignore incoming frames when paused; if submitUserSpeechOnPause is true, call forceEndSpeech().
    • Start/Stop: reset _isPaused in startListening(); guard vadInstance in stopListeningImpl() with null-check and log.
  • Add pause/resume UI functionality to example app
    • Example: Add dynamic pause button that appears only while actively listening
    • Example: Transform start button to "Resume" when paused, calling startListening() to resume
    • Example: Hide pause button when paused state is active
    • Example: Add separate stop button (red) available in both listening and paused states
    • Example: Implement proper state management for isListening and isPaused tracking
  • Add support for custom RecordConfig parameter in startListening() for non-web platforms
    • API: Add optional RecordConfig? recordConfig parameter to startListening() in VadHandlerBase.
    • Non-Web: Use custom RecordConfig if provided, otherwise fall back to default configuration with 16kHz sample rate, PCM16 encoding, echo cancellation, auto gain, and noise suppression.
    • Web: Accept the parameter for compatibility but ignore it (not applicable for web platform).
  • Bump record package to version 6.0.0
  • Example: Bump permission_handler package to version 12.0.0+1
  • Example: Bump audioplayers package to version 6.5.0

0.0.5 #

  • Add support for Silero VAD v5 model. (Default model is set to v4)
  • Automatically upsample audio to 16kHz if the input audio is not 16kHz (fixes model load failures due to lower sample rates).
  • Expose onRealSpeechStart event to notify when the number of speech positive frames exceeds the minimum speech frames (i.e. not a misfire event).
  • Expose onFrameProcessed event to track VAD decisions by exposing speech probabilities and frame data for real-time processing.
  • Update example app to show the onRealSpeechStart callback in action and introduce VAD Settings dialog to change the VAD model and other settings at runtime.
  • For web platform, bundle the required files within the package to avoid download failures when fetching from CDNs and to ensure offline support.
  • Update example app to log onFrameProcessed details for debugging.

0.0.4 #

  • Fixed a bug where default modelPath was not picked up, resulting in silent failure if modelPath was not provided.
  • Export VadIterator class for manual control over the VAD process for non-streaming use cases. Only available on iOS/Android.
  • Added comments for all public methods and classes.

0.0.3 #

  • Switch to onnxruntime package for inference on a separate isolate on iOS and Android to avoid using a full browser in the background, overall reducing the app size and improving performance.
  • Example app will show audio track slider with controls while speech segment is being played and it will reflect a misfire event on the UI if occurred.

0.0.2 #

  • Fix broken LICENSE hyperlink in README.md and add topics to pubspec.yaml

0.0.1 #

  • Initial release
