Thread the Web Speech API's interimResults flag through useVocal and the <Vocal> component so consumers can render live captions as the user is still speaking. In non-continuous mode, an interim result no longer discards the session: _onResult finalizes (matches commands and stops) only on the final segment, gated on SpeechRecognitionResult.isFinal. Absent isFinal (interimResults off, or synthetic aggregated events) still counts as final, so existing behavior is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Live/interim transcripts are the most compelling thing to show for speech recognition, and the demo revamp (stacked PR) uses this for its dictation card. Without it,
