Rime Coda TTS now available on Telnyx

26, May 2026

Rime Coda is now available on Telnyx, bringing Rime's flagship TTS model to the infrastructure agents choose. Coda delivers higher-quality multilingual speech with more voices and stronger language coverage, all processed on Telnyx's private network.

What's new

  • Rime Coda model: Rime's newest TTS model, built with an LLM backbone and dedicated speech inference engine for conversational speech.
  • 184 Rime voices plus 52 Telnyx-specific voices: Private-for-Telnyx voices across Hindi, Indian English, Saudi Arabic, Egyptian Arabic, Brazilian Portuguese, and US English.
  • 8-language coverage: English, Spanish, French, German, Portuguese, Japanese, Arabic, and Hindi.
  • On-network processing: Coda runs inside Telnyx-hosted models, keeping audio and inference on the same private backbone with no extra vendor hops.

Why it matters

  • Voice AI teams need voices that sound natural across live, multilingual conversations, not just single-language narration. Coda raises the quality floor for pronunciation, tone, and prosody.
  • Each vendor boundary in a Frankenstack TTS pipeline adds 30-80ms of latency. Running Coda on-network eliminates that hop, which matters for real-time agent conversations.
  • Teams serving multilingual callers in India, the Middle East, Brazil, and North America get Telnyx-specific voices tailored to those markets, reducing the integration work of stitching together multiple TTS providers.

Example use cases

  • Voice AI agents supporting callers in Hindi, Indian English, Arabic, Portuguese, Spanish, and English.
  • Customer support flows that need natural-sounding responses in real time.
  • IVRs and call automation that require clearer pronunciation across names, places, and regional accents.
  • Multilingual product experiences that need consistent voice quality across markets.
