For initial setup, you'll be prompted to allow the use of your microphone. Click "Allow" to grant permission. Once your microphone is enabled, you can start talking and ChatGPT will respond accordingly. If you encounter any issues, you can click the microphone icon again to turn it off.

The add-on also provides an icon that allows users to adjust audio settings. It's important to note that the response sentences may be read gradually, resulting in some unnatural pauses. Additionally, misreadings can occur occasionally, and there may be instances where speech recognition fails. VoiceChatGPT is an unofficial add-on and should be used with that understanding.
