Add Support for Speech-to-Text

[deep93333]

This feature is a nice-to-have for users who want to utilize audio synthesis in LLMChat. Implementing speech-to-text support will enhance the user experience by allowing users to interact with the chat interface using their voice.

Steps to Implement:

Integrate OpenAI's Speech-to-Text model.

Create a reusable hook that can be utilized throughout the application.

Ensure compatibility with existing features and models in LLMChat.

Expected Behavior:

Users should be able to speak into their microphone, and the audio input should be converted to text, which can then be processed by the chat interface.
