Choosing a model

voiceio models list           # known models, your fine-tunes, and which is active
voiceio models bench          # score candidates on your held-out clips (after `voiceio learn build`)
voiceio models use medium     # switch
Model Runtime License Notes
small faster-whisper MIT Default. About 5× realtime on a laptop CPU
medium faster-whisper MIT Better on names, about 2.5× slower
large-v3-turbo faster-whisper MIT Best Whisper for dictation; wants a GPU. Also the default learn teacher
distil-large-v3 faster-whisper MIT English only
sherpa:parakeet-tdt-0.6b-v3 sherpa-onnx CC-BY-4.0 Experimental. Fast, but no vocabulary biasing yet
whispercpp:http://… whisper.cpp server depends on the model Experimental. E.g. a Vulkan build on an AMD iGPU

Pick on your own audio, not leaderboards: for dictation full of names, how well a model can be biased matters more than its benchmark WER.

Licenses. voiceio ships no model weights. Each model is downloaded from its own source on first use, under its own license. The defaults are permissive (MIT). A fine-tune you make with voiceio learn inherits the license of the base model it was trained from.
