Speaker labels, timestamps, subtitles and translation exist only on `whisper-1` and `gpt-4o-transcribe-diarize`, which shut down on 26 February 2027 with no named replacement for those functions.\n\n## Before you call either\n\n### Amazon Transcribe\n\n1. Give every job a unique `TranscriptionJobName`. A retry with the same name fails with `ConflictException` rather than starting a second job\n2. Batch is a job. Poll `GetTranscriptionJob` or listen on EventBridge, then fetch the transcript URI\n3. Set `OutputBucketName`, because job records are deleted after 90 days\n4. Back off on `LimitExceededException`. It arrives as a 400, not a 429\n5. Set the organisation's AI services opt-out policy before sending customer audio\n\n### OpenAI Speech to Text\n\n1. Send `gpt-transcribe` to `POST /v1/audio/transcriptions` for recorded files. Use `languages` (a list), not `language`, and never send both.\n2. Keep each upload at 25 MB or less. Split longer audio between sentences and pass the previous chunk's text in `prompt`.\n3. For speaker labels send `gpt-4o-transcribe-diarize` with `response_format=diarized_json` and `chunking_strategy=auto` for audio over 30 seconds. Plan for its shutdown on 26 February 2027.\n4. Word timestamps, `srt`, `vtt` and `/v1/audio/translations` need `whisper-1`, which cannot stream and shuts down on the same date.\n5. On 429 or 503 wait at least `Retry-After` when present, then back off with jitter. Do not retry `credit_balance_exhausted` or spend-limit errors.\n\n## Questions\n\n### Which is better for AI agents, Amazon Transcribe or OpenAI Speech to Text?\n\nAmazon Transcribe scores 73.4 (BB) on agent readiness against OpenAI Speech to Text's 72.4 (BB), and leads in 4 of 7 scored categories.
