speech (Rust)

Crate Layout

• voice.rs: Voice/VoiceSegment interfaces
• speech.rs: Speech/SpeechSegment interfaces
• asr.rs: ASR multiplexer and traits
• tts.rs: TTS multiplexer and traits
• segment.rs: sentence segmentation utilities
• util.rs: speech collector and iterator helpers

Public Interfaces

• Voice: Voice, VoiceSegment, VoiceStream
• Speech: Speech, SpeechSegment, SpeechStream
• ASR: StreamTranscriber, Transcriber (async), ASR
• TTS: Synthesizer, TTS (async)
• Segmentation: SentenceSegmenter, SentenceIterator

Design Notes

• Async traits are used across ASR/TTS and stream interfaces.
• ASR and TTS use a trie-based mux with async read/write locks.
• SpeechCollector composes a SpeechStream into a single Speech.

Differences vs Go

• No global mux singletons; callers construct ASR/TTS explicitly.
• Async AsyncRead is used for text input in TTS.
