Moore Threads AIBook Speech Recognition API
Speech-to-text in two shapes. A realtime WebSocket at /api/v1/asr accepts 16 kHz mono audio and returns SentenceBegin / SentenceChanged / SentenceEnd events with optional punctuation, ITN, disfluency removal, speaker diarization, confidence and word-level timing. A recording-file HTTP API on the same base submits a job by URL or chunked upload, then polls for the transcript or receives it on a callback URL; audio up to 512 MB / 5 hours, results retained 72 hours. Bearer token authentication.
