Introduction to Audio GPT

In this video, we will explore how to build audio GPT, which allows us to Interact with OpenAI's chatbot using our microphone and receive audio responses. We will discuss the requirements, import the necessary libraries, and walk through the process step by step.

Requirements

To get started with audio GPT, we need the following:

• An OpenAI API Key
• Jet, or an open source model if preferred
• Access to 11 Labs to obtain a voice for the chatbot
• A code editor, such as VS Code
• Python and the required libraries

Importing Libraries

We begin by importing the necessary libraries, including default libraries like os and keyboard for keyboard interactions. We also import dotenv to load our environmental variables, tempfile to store the audio file, openai for communication with the OpenAI API, and sounddevice and soundfile to Record and play back audio.

Loading Environment Variables

To securely store our API keys, we use dotenv to load our environmental variables. We retrieve our OpenAI API key and 11 Labs API key from the loaded variables.

Sending Messages to the Chat Completion Model

Before we can interact with the chatbot, we define the messages that will be sent to the chat completion model from OpenAI. We Create a list containing dictionaries, where each dictionary represents a message. The role parameter determines whether the message is from the user or the assistant, and the content parameter contains the text of the message. This allows us to prime the model with a prompt.

Recording Audio

In order to have a conversation with the chatbot, we need to record audio input. We define the record_audio function, which takes parameters for duration, sample rate, and channels. Using the sounddevice library, we record the audio from our microphone and store it in a variable. We use soundfile to save the recorded audio as a WAV file.

Transcribing the Audio

Once we have recorded the audio, we need to transcribe it into text so that we can send it to the chat completion model. The transcribe_audio function takes the recorded audio as input, as well as the sample rate. It opens the audio file, transcribes it using the OpenAI API, and returns the transcribed text.

Generating Audio Response

After transcribing the audio, we send the transcribed text to the chat completion model using the OpenAI API. We define the generate_response function, which takes the transcribed text as input and sends it to the chat completion model. We retrieve the response message from the API response and return it.

Playing the Audio

To hear the response from the chatbot, we need to play the audio. We define the play_audio function, which takes the response message text, voice, and model as input. Using 11 Labs, we generate audio from the text using the specified voice and model. We then use the play function to play the generated audio.

Running the Audio GPT Program

To initiate the audio GPT program, we create a loop that allows us to interact with the chatbot. We Prompt the user to press the space bar to start, and once they do, we begin recording audio, transcribe it, generate a response, and play the audio. The loop continues until the user presses the escape key to exit the program.

Please see the video for a demonstration and more detailed explanations.

Highlights

• Build audio GPT to interact with OpenAI's chatbot using audio input and output.
• Record audio from the microphone and transcribe it into text.
• Use the chat completion model from OpenAI to generate a response.
• Convert the response text into audio using 11 Labs.
• Play the audio response back to the user.

FAQ

Q: Can I use an open source model instead of Jet? A: Yes, you have the option to use an open source model with audio GPT. However, you will need to modify the code accordingly.

Q: Is 11 Labs free to use? A: Yes, you can register for free access to 11 Labs, which allows you to obtain a voice for the chatbot.

Q: Can I customize the initial prompt for the chat completion model? A: Absolutely! You can modify the initial prompt to tailor the conversation to your specific needs.
