WhisperLiveKit Releases

Major release with new CLI parameters, backend policy restructuring, and frontend improvements including translation buffer display.

Nov 15, 2025

Major release separating translation engine into dedicated NLLW package, adding Silero VAD v6 support, and expanding model format support.

Oct 30, 2025

Initial release adding custom model support, Chrome extension and web interface unification, and various bug fixes.

Oct 6, 2025

This minor release introduces auto-detection of language with automatic transcript recomputation when the detected language differs from the initial detection, and enables NLLB Translation to work with auto language mode. Additionally, SVG files are now loaded once in JavaScript to eliminate StaticFile dependency and improve loading in network-constrained environments.

Sep 24, 2025

This release focuses on enhancing the Live Translation with NLLB feature by adding backend flexibility (switchable via --nllb-backend) and configurable model sizes (600M to 1.3B via --nllb-size). It also introduces frontend AudioWorklet support for PCM input and includes several bug fixes related to translation performance, websocket timeouts on low-end devices, and buffer positioning issues.

Sep 17, 2025

Release 0.2.9 introduces a beta live translation feature using NLLB, adds raw PCM input support and a punctuation split toggle, while fixing several GPU/CUDA issues with simulstreaming and improving overall stability.

Sep 11, 2025

This release focuses on performance improvements for the simulstreaming backend by defaulting to MLX-Whisper or Faster-Whisper encoders with AlignAtt policy, while also reducing vRAM usage through shared encoder loading. The release also adds Python 3.14/3.15 compatibility, removes the Triton <3 requirement, and introduces frontend enhancements including a microphone picker and simplified deployment via a single inline HTML file.

Sep 2, 2025

Release 0.2.7 introduces major diarization improvements with Sortformer as the new default backend, delivering 6x faster processing and significantly better speaker detection while reducing memory usage through shared model loading.

Aug 27, 2025

This release (0.2.6) of WhisperLiveKit introduces significant default behavior changes including enabling Voice Activity Control (VAC) by default and making the simulstreaming backend the default transcription method, both aimed at improving transcription accuracy and resource management.

Aug 21, 2025

This release (0.2.5) of WhisperLiveKit introduces significant backend architecture improvements including multi-user support for shared Whisper model instances, enhanced performance monitoring with faster lag metric updates, and reduced hallucinations during silent periods. The frontend also receives notable enhancements with dark theme support, three distinct silence indicators, and improved UX during transcription.

Aug 13, 2025

This release focuses on bug fixes and core improvements for WhisperLiveKit, notably updating the SimulStreaming Whisper core from version 20230918 to 20250625 to fix tensor mismatch issues on some GPUs, and resolving a critical diarization queue bug that was sending the entire audio buffer instead of just the latest chunk.

Aug 2, 2025

Replaces the ffmpeg-python library with raw ffmpeg calls to resolve systematic crashes and improve server stability.

Jul 4, 2025

Introduces a new SimulStreaming backend that offers up to 5x faster transcription speeds compared to standard methods.

Jun 27, 2025

Optimizes diarization performance and introduces punctuation-based speaker splitting for more natural transitions.

Jun 19, 2025

Refactors the codebase to separate command-line parsing and web interface into dedicated modules while improving programmatic flexibility.

Jun 16, 2025

Fixes issues with VAC transcription and improves backend logging and error messaging.

May 28, 2025

Improves logging granularity and error handling mechanisms to ensure proper termination of transcription tasks.

May 7, 2025

Optimizes server performance by disabling auto-reload and fixes blocking IO issues, while adding SSL support for secure local connections.

Apr 13, 2025

Adds Docker support and resolves import errors while improving backend auto-selection and WebSocket fallback logic.
