Deepgram Flux Multilingual STT Now Available for LiveKit Agents on Telnyx

Deepgram Flux Multilingual STT is now available for LiveKit agents on Telnyx. Set the model to deepgram/flux-multi or flux-multi in the Telnyx LiveKit plugin to transcribe conversations where speakers switch between languages, with the same low-latency Flux turn-taking controls already available for English.

What's new

• Flux Multilingual model: Set model="deepgram/flux-multi" or model="flux-multi" in the Telnyx LiveKit plugin to enable multilingual speech recognition with automatic language detection.
• Language hints: Pass language_hint=["en", "es"] to bias detection toward expected languages. Telnyx normalizes locale tags (e.g. "pt-BR" becomes "pt").
• Flux turn-taking controls: The same eot_threshold, eot_timeout_ms, and eager_eot_threshold parameters available for English Flux work identically with Flux Multilingual.

Why it matters

• Voice AI agents serving global customers need to handle callers who switch languages mid-conversation, or who speak a different language than the default. Flux Multilingual detects the spoken language automatically, no configuration per call needed.
• Running multilingual STT through the same Telnyx-hosted pipeline keeps audio and transcription on the same private backbone, avoiding the latency added when routing through a separate provider.

Example use cases

• A customer support line serving North America, where callers may switch between English and Spanish mid-call.
• A travel booking agent handling multilingual callers across Europe, using language_hint to bias toward likely languages.
• A healthcare platform with patients who speak their primary language but switch to English for medical terminology.
