This is an ongoing project where I'm building my own Google Home / Alexa style device that can be interacted with via voice commands.
Currently it can detect a wakeup keyphrase, such as "Ok, GPT!" and then listen to a voice command. Speech recognition is done with OpenAI Whisper, locally. The command is then sent to the ChatGPT API and the response is spoken via the OpenAI Text-to-Speech API.
You need to initialize it with the init.py script by saying the keyphrase you want to wake up the device with 10 times. After that you can run recognize.py and it will recognize when you say the keyphrase and then listen for the command.
$ export OPENAI_API_KEY=YOUR_API_KEY
$ pip install -r requirements.txt
$ python3 init.py
$ python3 recognize.pyThe building of this project is documented on my YouTube channel.
