WebAI StudioASR Quality Tier Lab
SpeechRead the same passage against the command, dictation, and conversation models — then compare accuracy and latency.
Why On-Device?
The quality-levels explainer lets sites pick the right on-device model for the job — this lab makes the size/accuracy/latency trade-off measurable on your own hardware.
Interactive Demo
Smallest model — short phrases, limited vocabulary.
Mid-size model — continuous single-speaker speech.
Largest model — complex vocabulary, high noise.
Implementation Code

56 demos, all running on-device.
Tongue Twister Trial
Say "she sells seashells" as fast as you can — the on-device recognizer scores how much of it survived.
Live Translated Captions
Speak into the mic: on-device captions appear instantly, and a second track renders them live in another language.
Dictate & Polish
Speak your messy first draft, then let the Proofreader and Rewriter turn it into publishable text.
