The terms, last revised 14 June 2024, let Cartesia train on inputs and outputs unless the customer opts out, and zero data retention is an Enterprise setting. Ink 2 has no batch endpoint and no diarisation.\n\n**Google Cloud Speech-to-Text.** Audio isn't stored or used for training unless the project opts in to data logging. No release note since 2025-11-13.\n\n## Before you call either\n\n### Cartesia Ink\n\n1. Use `wss://api.cartesia.ai/stt/turns/websocket` with `model=ink-2`, `encoding`, `sample_rate` and `cartesia_version=2026-08-14`. All four are required.\n2. Send raw mono audio in chunks of about 100 ms at the speed it was spoken. Pushing a whole file into the socket can return an internal server error.\n3. Read the final text from `turn.end` only. `transcript` is cumulative within a turn, so joining `turn.update` events duplicates text.\n4. Send `{\"type\": \"close\"}` after the last audio and keep reading until the server closes the socket, or the buffered tail is lost.\n5. Check `encoding` and `sample_rate` against the source before sending. The docs say the server might not return an error when they are wrong.\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## Questions\n\n### Which is better for AI agents, Cartesia Ink or Google Cloud Speech-to-Text?\n\nGoogle Cloud Speech-to-Text scores 70.2 (BB) on agent readiness against Cartesia Ink's 67.9 (B), and leads in 3 of 7 scored categories. Cartesia Ink leads on schema \u0026 documentation, payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Cartesia Ink and Google Cloud Speech-to-Text need an API key?\n\nCartesia Ink needs an API key. Google Cloud Speech-to-Text uses an OAuth sign-in.\n\n### Can an agent call Cartesia Ink and Google Cloud Speech-to-Text without installing anything?\n\nYes. Cartesia Ink has a hosted endpoint at https://api.cartesia.ai and Google Cloud Speech-to-Text at https://speech.googleapis.com/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/cartesia-ink-stt-vs-google-speech-to-text.json, and with the fewest tokens: https://www.anchorterminal.com/compare/cartesia-ink-stt-vs-google-speech-to-text.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"cartesia-ink-stt\", \"b\": \"google-speech-to-text\"}`.
