Create a key restricted to speech-to-text with a credit quota and an expiry\n2. Use `source_url` for hosted files instead of downloading and re-uploading\n3. Set `webhook=true` for long files so the call doesn't block\n4. Back off exponentially on any of the three 429 codes\n5. Opt out under Data use before sending customer audio. It only covers later uploads\n\n### Soniox Speech-to-Text\n\n1. Pass `audio_url` for public files and skip the upload step. Delete uploaded files or they count against the 10 GB quota for 30 days\n2. Use the `context` field for names and domain terms\n3. Buffer audio while the WebSocket connects, then flush it after the config message\n4. Split anything over 300 minutes. The cap is fixed\n5. Set `client_reference_id` so failed or duplicate requests can be traced in the usage log\n\n## Other comparisons with ElevenLabs Scribe Speech to Text API or Soniox Speech-to-Text\n\n- [Amazon Transcribe vs ElevenLabs Scribe Speech to Text API](https://www.anchorterminal.com/compare/amazon-transcribe-vs-elevenlabs-scribe.md)\n- [Amazon Transcribe vs Soniox Speech-to-Text](https://www.anchorterminal.com/compare/amazon-transcribe-vs-soniox-stt.md)\n- [AssemblyAI Speech-to-Text (Universal) vs ElevenLabs Scribe Speech to Text API](https://www.anchorterminal.com/compare/assemblyai-stt-vs-elevenlabs-scribe.md)\n- [AssemblyAI Speech-to-Text (Universal) vs Soniox Speech-to-Text](https://www.anchorterminal.com/compare/assemblyai-stt-vs-soniox-stt.md)\n- [Azure AI Speech speech-to-text vs ElevenLabs Scribe Speech to Text API](https://www.anchorterminal.com/compare/azure-speech-to-text-vs-elevenlabs-scribe.md)\n- [Azure AI Speech speech-to-text vs Soniox Speech-to-Text](https://www.anchorterminal.com/compare/azure-speech-to-text-vs-soniox-stt.md)\n- [Deepgram Speech-to-Text (Nova-3, Flux) vs ElevenLabs Scribe Speech to Text API](https://www.anchorterminal.com/compare/deepgram-stt-vs-elevenlabs-scribe.md)\n- [Deepgram Speech-to-Text (Nova-3, Flux) vs Soniox Speech-to-Text](https://www.anchorterminal.com/compare/deepgram-stt-vs-soniox-stt.md)\n- [ElevenLabs Scribe Speech to Text API vs Gladia Speech-to-Text API + MCP](https://www.anchorterminal.com/compare/elevenlabs-scribe-vs-gladia-stt.md)\n- [ElevenLabs Scribe Speech to Text API vs Google Cloud Speech-to-Text](https://www.anchorterminal.com/compare/elevenlabs-scribe-vs-google-speech-to-text.md)\n- [ElevenLabs Scribe Speech to Text API vs Rev AI Speech-to-Text API](https://www.anchorterminal.com/compare/elevenlabs-scribe-vs-rev-ai-stt.md)\n- [ElevenLabs Scribe Speech to Text API vs Speechmatics Speech-to-Text](https://www.anchorterminal.com/compare/elevenlabs-scribe-vs-speechmatics-stt.md)\n- [Gladia Speech-to-Text API + MCP vs Soniox Speech-to-Text](https://www.anchorterminal.com/compare/gladia-stt-vs-soniox-stt.md)\n- [Google Cloud Speech-to-Text vs Soniox Speech-to-Text](https://www.anchorterminal.com/compare/google-speech-to-text-vs-soniox-stt.md)\n- [Rev AI Speech-to-Text API vs Soniox Speech-to-Text](https://www.anchorterminal.com/compare/rev-ai-stt-vs-soniox-stt.md)\n- [Soniox Speech-to-Text vs Speechmatics Speech-to-Text](https://www.anchorterminal.com/compare/soniox-stt-vs-speechmatics-stt.md)\n",
