Falcon 2 concurrency is 2 outside US-East on free and pay as you go, 5 on US-East.\n\n## Before you call either\n\n### Deepgram Text-to-Speech (Aura-2, Flux TTS)\n\n1. Set `mip_opt_out=true` on every request if the text mustn't be kept for training.\n2. Split Aura-2 REST text under 2,000 characters or expect a 413.\n3. Pass `model` on `/v2/speak`, where it's required.\n4. Strip SSML before sending, since it's removed with an `INPUT_MARKUP_STRIPPED` warning.\n5. Back off exponentially on 429 and keep traffic in one project.\n\n### Murf TTS API + MCP\n\n1. Send `locale` on every request, since `multiNativeLocale` was replaced on 2026-03-05.\n2. Split text into chunks under 3,000 characters per request.\n3. Use the US-East host for 5 concurrent Falcon 2 calls instead of 2.\n4. Set `encodedAsBase64` to get audio inline and skip the expiring download link.\n5. Back off on 429 and close WebSocket contexts with `end: true` to free slots.\n\n## Other comparisons with Deepgram Text-to-Speech (Aura-2, Flux TTS) or Murf TTS API + MCP\n\n- [Amazon Polly vs Deepgram Text-to-Speech (Aura-2, Flux TTS)](https://www.anchorterminal.com/compare/amazon-polly-vs-deepgram-tts.md)\n- [Amazon Polly vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/amazon-polly-vs-murf-tts.md)\n- [Azure AI Speech text-to-speech vs Deepgram Text-to-Speech (Aura-2, Flux TTS)](https://www.anchorterminal.com/compare/azure-text-to-speech-vs-deepgram-tts.md)\n- [Azure AI Speech text-to-speech vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/azure-text-to-speech-vs-murf-tts.md)\n- [Cartesia Sonic TTS API + MCP vs Deepgram Text-to-Speech (Aura-2, Flux TTS)](https://www.anchorterminal.com/compare/cartesia-tts-vs-deepgram-tts.md)\n- [Cartesia Sonic TTS API + MCP vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/cartesia-tts-vs-murf-tts.md)\n- [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs ElevenLabs Text to Speech API + MCP](https://www.anchorterminal.com/compare/deepgram-tts-vs-elevenlabs-tts.md)\n- [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/deepgram-tts-vs-playht-tts.md)\n- [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs Resemble AI Text-to-Speech API](https://www.anchorterminal.com/compare/deepgram-tts-vs-resemble-ai-tts.md)\n- [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/deepgram-tts-vs-rime-tts.md)\n- [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/deepgram-tts-vs-soniox-tts.md)\n- [ElevenLabs Text to Speech API + MCP vs Murf TTS API + MCP](https://www.anchorterminal.com/compare/elevenlabs-tts-vs-murf-tts.md)\n- [Murf TTS API + MCP vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/murf-tts-vs-playht-tts.md)\n- [Murf TTS API + MCP vs Resemble AI Text-to-Speech API](https://www.anchorterminal.com/compare/murf-tts-vs-resemble-ai-tts.md)\n- [Murf TTS API + MCP vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/murf-tts-vs-rime-tts.md)\n- [Murf TTS API + MCP vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/murf-tts-vs-soniox-tts.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Deepgram Text-to-Speech (Aura-2, Flux TTS) vs Murf TTS API + MCP", "url": "" } ], "description": "Deepgram Text-to-Speech (Aura-2, Flux TTS) has a score of 73 (BB) against Murf TTS API + MCP's 70.9 (BB).
