No release note since 2025-11-13.\n\n**OpenAI Speech to Text.** `gpt-transcribe` costs $0.0045 an audio minute, and the audio endpoints keep no abuse-monitoring logs or application state. 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### Google Cloud Speech-to-Text\n\n1. Call Chirp 3 on the `us` or `eu` endpoint. It isn't listed for the `global` location\n2. Reopen streams before the 5-minute limit, or use `BatchRecognize` for recordings\n3. Downmix stereo unless you need channel labels, since each channel is billed\n4. Set dynamic batch on offline jobs to cut the price from $0.016 to $0.003 a minute\n5. Back off on `RESOURCE_EXHAUSTED`. The Speech docs don't give a retry interval\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, Google Cloud Speech-to-Text or OpenAI Speech to Text?\n\nOpenAI Speech to Text scores 72.4 (BB) on agent readiness against Google Cloud Speech-to-Text's 70.2 (BB), and leads in 3 of 7 scored categories. Google Cloud Speech-to-Text leads on reliability, security \u0026 auth and transparency \u0026 trust.\n\n### Do Google Cloud Speech-to-Text and OpenAI Speech to Text need an API key?\n\nGoogle Cloud Speech-to-Text uses an OAuth sign-in. OpenAI Speech to Text needs an API key.\n\n### Can an agent call Google Cloud Speech-to-Text and OpenAI Speech to Text without installing anything?\n\nYes. Google Cloud Speech-to-Text has a hosted endpoint at https://speech.googleapis.com/v2 and OpenAI Speech to Text at https://api.openai.com/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/google-speech-to-text-vs-openai-speech-to-text.json, and with the fewest tokens: https://www.anchorterminal.com/compare/google-speech-to-text-vs-openai-speech-to-text.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"google-speech-to-text\", \"b\": \"openai-speech-to-text\"}`.
