feat(ios): live streaming transcription preview (Wispr-style)#25
Merged
Conversation
Groq Whisper is batch-only, so the live "words appear as you speak" feel comes from Apple's on-device SFSpeechRecognizer as a PREVIEW; the accurate final transcript still comes from the server and is what gets inserted. - LiveTranscriber: on-device SFSpeechRecognizer wrapper (partial results, requiresOnDeviceRecognition when supported, locale from the language setting). Degrades gracefully — if speech permission is denied/unavailable it's a no-op and the server path still works. - AudioRecorder fans its raw tap buffers out via onBuffer (one tap per node). - DictationController owns the LiveTranscriber, feeds it (capturing the transcriber, not the @mainactor self, so it stays off the audio thread's actor), starts/stops it with recording, and requests speech auth once. - KeyboardView shows the interim words during recording (head-truncated so the latest stay visible), falling back to the waveform until words arrive. - Info.plist: NSSpeechRecognition + NSMicrophone usage descriptions. Additive — the existing record→POST→insert flow is unchanged. Build- + test- verified (31 iOS tests). Co-Authored-By: Claude Opus 4.8 <[email protected]>
