Project Structure

The project is divided into four main python files:

1. main.py: The main script that integrates all other modules, listens for the wake word, manages the audio recording, and handles the interaction with OpenAI and AWS Polly.

2. stt_service.py: Handles the speech-to-text conversion

3. tts_service.py: Handles the text-to-speech conversion using Amazon Polly.

4. input_listener.py: Handles the audio recording and silence detection.

5. chat_gpt_service.py: Manages the interaction with OpenAI's GPT-3 model.

There is also a configuration file, config.json, which stores important parameters and keys.
