# Specify STT language for Telnyx AI Agents

### 10, Jun 2025

Telnyx is excited to announce that you can now specify the speech-to-text (STT) language for your AI Agents. Voice interactions often occur in languages other than English, like Spanish, French, Polish, and more. Relying on auto-detection for STT increases risk of transcription errors, compliance gaps, and downstream automation failures.

## What’s new

* Language selection for speech-to-text. Set a specific language code for your AI Agent, not just “auto-detect.”
* Improved transcription accuracy. Fewer mistakes when a single language is expected, especially for non-English voices.
* Streamlined configuration. Pick your preferred language directly in the AI Assistant Builder.
* Better compliance support. More reliable transcripts for regulated industries.

## Why it matters

For organizations with high call volumes and strict compliance needs, selecting your speech-to-text language means fewer critical errors, faster automation, and stronger audit trails. Configure your language of choice, verify with a test call, and keep your voice communications clear and reliable.

## Getting started

1. [Sign up](https://telnyx.com/sign-up) or [log in](https://portal.telnyx.com/#/login/sign-in) to your Telnyx Mission Control Portal account.
2. Navigate to the AI Assistants section.
3. In your Agent, choose the openai/whisper-large-v3-turbo transcription model.
4. Select your language of choice.
5. Test your assistant directly within the AI Assistant Builder.
