# Guide to Text-to-Speech Conversion

LobeChat supports text-to-speech conversion, allowing users to input content through voice and have the AI output read aloud through speech.

## Text-to-Speech (TTS)

Select any content in the chat window, choose `Text-to-Speech`, and the AI will use the TTS model to read the text content aloud.

## Speech-to-Text (STT)

Select the voice input feature in the input window, and LobeChat will convert your speech to text and input it into the text box. After completing the input, you can send it directly to the AI.
