WhisperMix

WhisperMix transcribes audio to text with one API and multiple backends.

Use this skill when the user wants speech-to-text from an audio file (.mp3, .wav, .m4a, .ogg, .flac, .webm) in a Node.js project.

Do not use for TTS, translation, or live microphone streaming.

Choose a model (quick)

• Cloud, best quality/speed: groq/whisper-large-v3 or openai/whisper-1
• Local, fastest startup: efederici/parakeet-tdt-0.6b-v3-int4
• Local, better language control: xenova/whisper-large-v3

Important limits:

• Local models are file-only (fromFile), no fromStream.
• API models need OPENAI_API_KEY or GROQ_API_KEY.
• ffmpeg is required for long files.
