Customize language

Language configuration in TEN Agent involves two key components:

• Input language: The language for speech recognition (STT)
• Output language: The language for speech synthesis (TTS)

This guide shows you how to configure both components for different agent types.

Before you start:

• Complete the Agent quickstart
• Verify the playground is running at localhost:3000

For agents using separate STT modules:

1. Open the playground at localhost:3000

2. Select the voice_assistant graph type

3. Click the settings button next to the graph selector

4. Choose STT from the extension dropdown

5. Update the language property to your target language

6. Click Save Changes

Language codes vary by STT provider. Check your provider's documentation for supported language options.

For agents with RTC-integrated Azure STT:

2. Select the voice_assistant_integrated_stt graph type

3. Click the settings button next to the graph selector

4. Choose RTC from the extension dropdown

5. Update the language property (for example, use en-US for English)
