Whisper-Large-V3-Distil-Multi4-v0.2

A multilingual distilled Whisper model with 2 decoder layers, supporting 4 European languages: English, French, Spanish, and German.

The model was trained during my work on Distil-Large-v3.5.

A notable feature is its native support for code-switching. The model has the ability to switch languages within a single segment transcription by automatically producing a new language token when it detects a language change (as demonstrated in the following example).

The <|yue|> language token has been repurposed during training to act as an automatic language detection token that enables code-switching during inference. To use this feature, simply set the language parameter to cantonese (used by default).

The model's performance is below both the monolingual distilled version and Whisper-Large-v3-Turbo. Future work should investigate better training procedures and possibly incorporate more data to effectively compress multilingual capabilities into a single model.
