A compact, powerful, and intuitive home assistant powered by Google's Speech-to-Text and Text-to-Speech APIs, and OpenAI's ChatGPT. Speak to it, and it responds!

This project leverages an ESP32-S3-Mini microcontroller equipped with a microphone and speaker, creating a handy device capable of converting spoken questions to text, generating meaningful responses using ChatGPT, converting these responses back to speech, and audibly presenting them. This hands-free approach allows for easy interaction, akin to having your very own smart assistant!

• ESP32-S3-Mini Feather by Adafruit
• Inmp441 (or any other I2S Mic)
• MAX98357A (or any other class D speaker amp)
• 4-8 ohm speaker
• Micro SD breakout board
• Micro SD card

• Arduino IDE
• ESP32 Arduino Core
• Google Cloud account (for Google's Speech-to-Text and Text-to-Speech APIs)
• OpenAI account (for ChatGPT)

1. Clone this repository into your local machine.
2. Open Arduino IDE and load the provided .ino file.
3. Ensure all required libraries mentioned in the code are installed.
4. Replace placeholder values for Google Cloud and OpenAI API keys in the code with your own.
5. Compile and upload the sketch to your ESP32-S3-Mini board.

• Press the reset button to activate the device.
• Speak your query into the microphone. Your voice will be recorded and stored on the micro SD card.
• The device will convert your voice recording into text using Google's Speech-to-Text API.
• The transcribed text will be sent to ChatGPT to generate a meaningful response.
• The response from ChatGPT will be converted back into speech using Google's Text-to-Speech API.
• Finally, the synthesized speech will be played back to you through the speaker, answering your query!

Remember to ensure your device has stable access to the internet, as the APIs used in this project require online communication. Also, be aware of any potential costs associated with the usage of Google Cloud and OpenAI APIs.
