speech (Go)

Package Layout

• voice.go: Voice/VoiceSegment interfaces
• speech.go: Speech/SpeechSegment interfaces
• asr.go: ASR multiplexer and interfaces
• tts.go: TTS multiplexer and interfaces
• segment.go: default sentence segmentation
• util.go: collectors and copy helpers
• Provider implementations: asr_doubao_sauc.go, tts_doubao_v1.go, tts_doubao_v2.go, tts_minimax.go

Public Interfaces

• Voice: Voice, VoiceSegment, VoiceStream
• Speech: Speech, SpeechSegment, SpeechStream
• ASR: StreamTranscriber, Transcriber, ASR mux + helpers
• TTS: Synthesizer, TTS mux + helpers
• Segmentation: SentenceSegmenter, SentenceIterator

Design Notes

• Global muxes ASRMux and TTSMux provide default routing.
• ASR uses Opus frame streams (opusrt.FrameReader).
• DefaultSentenceSegmenter splits by punctuation with a rune cap.
• CollectSpeech and CopySpeech help aggregate or export streams.

Usage Notes

• Transcribe falls back to streaming when the backend does not implement the Transcriber interface.
• Revoice streams existing speech into a TTS backend via a pipe.
