WhisperLiveKit-Breeze-ASR-25

Breeze ASR 25 for WhisperLiveKit

This repository repackages Breeze ASR 25 into a layout that works directly with WhisperLiveKit custom models and also remains usable with faster-whisper / CTranslate2.

It combines:

• the original Whisper decoder checkpoint from MediaTek-Research/Breeze-ASR-25
• the CTranslate2 conversion from SoybeanMilk/faster-whisper-Breeze-ASR-25

This is a compatibility packaging repo. It does not introduce new training or new weights.

Included files

• breeze-asr-25.pt: Whisper decoder checkpoint for WhisperLiveKit SimulStreaming
• model.bin: CTranslate2 encoder/decoder weights for faster-whisper
• config.json, preprocessor_config.json, tokenizer.json, vocabulary.json: faster-whisper runtime files

WhisperLiveKit usage

Point WhisperLiveKit to this Hugging Face repo ID or to a local snapshot of this directory.

Example:

whisperlivekit-server \
  --backend simulstreaming \
  --model-path YOUR_USERNAME/YOUR_REPO_NAME

If you want to set alignment heads explicitly, use WhisperLiveKit's scripts/determine_alignment_heads.py against breeze-asr-25.pt and pass the result with --custom-alignment-heads.

faster-whisper usage

from faster_whisper import WhisperModel

model = WhisperModel("YOUR_USERNAME/YOUR_REPO_NAME", compute_type="float16")
segments, info = model.transcribe("audio.wav")

for segment in segments:
    print(f"[{segment.start:.2f}s -> {segment.end:.2f}s] {segment.text}")

Provenance

• Original model: MediaTek-Research/Breeze-ASR-25
• Existing CTranslate2 conversion: SoybeanMilk/faster-whisper-Breeze-ASR-25
• Compatibility packaging assembled for WhisperLiveKit custom-model usage from those two upstream artifacts
