What it is

Amazon Transcribe Streaming is the real-time variant of Amazon Transcribe, accepting audio over HTTP/2 or WebSocket and returning incremental transcripts. Supports speaker partitioning, vocabulary filtering, and PII redaction. Region availability is narrower than batch. Per-minute pricing is similar to batch but billed per second of streamed audio. Best fit: live captioning, contact-center real-time use cases. Caveats: pricing parity with batch but with stricter region / language matrix. Pricing as listed: from $0.024/min. Feature flags from vendor docs: speaker diarization, word-level timestamps, streaming, HIPAA-eligible under BAA. Directory tags: commercial-api, hyperscaler, streaming. Last vendor-page check: 2026-05-12.

Best for: Live captioning, contact-center real-time use cases.
Watch out for: Pricing parity with batch but with stricter region / language matrix.
