Falcon 2 concurrency is 2 outside US-East on free and pay as you go, 5 on US-East. **Soniox Text-to-Speech.** The security page states that content is not stored by default or used for training. Audio output is capped at two minutes per request or stream. ## Before you call either ### Murf TTS API + MCP 1. Send `locale` on every request, since `multiNativeLocale` was replaced on 2026-03-05. 2. Split text into chunks under 3,000 characters per request. 3. Use the US-East host for 5 concurrent Falcon 2 calls instead of 2. 4. Set `encodedAsBase64` to get audio inline and skip the expiring download link. 5. Back off on 429 and close WebSocket contexts with `end: true` to free slots. ### Soniox Text-to-Speech 1. Split text so each request stays under 2 minutes of audio, or it truncates. 2. Branch on `error_type`, not the message, and back off on `limit_exceeded`. 3. Use a temporary API key for browser clients. 4. Use bracketed audio tags such as `[whispering]` instead of SSML. 5. Pick the regional host (EU, Japan, India) that matches your data residency. ## Other comparisons with Murf TTS API + MCP or Soniox Text-to-Speech - [Amazon Polly vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/amazon-polly-vs-murf-tts.md) - [Amazon Polly vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/amazon-polly-vs-soniox-tts.md) - [Azure AI Speech text-to-speech vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/azure-text-to-speech-vs-murf-tts.md) - [Azure AI Speech text-to-speech vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/azure-text-to-speech-vs-soniox-tts.md) - [Cartesia Sonic TTS API + MCP vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/cartesia-tts-vs-murf-tts.md) - [Cartesia Sonic TTS API + MCP vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/cartesia-tts-vs-soniox-tts.md) - [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/deepgram-tts-vs-murf-tts.md) - [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/deepgram-tts-vs-soniox-tts.md) - [ElevenLabs Text to Speech API + MCP vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/elevenlabs-tts-vs-murf-tts.md) - [ElevenLabs Text to Speech API + MCP vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/elevenlabs-tts-vs-soniox-tts.md) - [Murf TTS API + MCP vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/murf-tts-vs-playht-tts.md) - [Murf TTS API + MCP vs Resemble AI Text-to-Speech API](https://www.anchorterminal.com/compare/murf-tts-vs-resemble-ai-tts.md) - [Murf TTS API + MCP vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/murf-tts-vs-rime-tts.md) - [PlayHT Text-to-Speech API vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/playht-tts-vs-soniox-tts.md) - [Resemble AI Text-to-Speech API vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/resemble-ai-tts-vs-soniox-tts.md) - [Rime TTS API + MCP vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/rime-tts-vs-soniox-tts.md)
