how can I change the language in tts in the runtime?

Thanks for reaching out, Aditya. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.


You can change the language in Text-to-Speech (TTS) during runtime in LiveKit by using the `update_options` method provided by the TTS plugin you are using. Here are examples for different plugins:
• *Neuphonic TTS:* Use the `lang_code` parameter:`tts.update_options(lang_code="en-US")`
• *Google TTS:* Use the `language` parameter:`tts.update_options(language="en-US")`
• *LMNT TTS:* Use the `language` parameter:`tts.update_options(language="en")`
• *PlayAI TTS:* Use the `language` parameter:`tts.update_options(language="en-US")`
• *ElevenLabs TTS:* Use the `language` parameter:`tts.update_options(language="en")`
The specific language codes and formats may vary between providers, so please refer to the documentation of the TTS provider you are using for supported language codes.
