Domain Dictation Lab

Switch domains — medical, legal, software engineering — and the dictation bias list flips. Two transcripts run in parallel (one biased, one not) so you can hear the difference: "atrial fibrillation" stays atrial fibrillation, not "a treble fibulation". Add your own phrases per domain and tune the boost.

Note: requires SpeechRecognition and microphone permission. The bias-phrase API is shipping in Chrome 142; older versions accept the property but ignore it.
