🗣️ GPT-4 Text-to-Speech Application

This is an interactive application that uses the OpenAI API to generate responses from GPT-4, and then converts them to speech using the Eleven Labs API. 🎙️

🛠️ Prerequisites

You will need the following tools installed:

• Node.js
• npm

And you'll also need API keys for the following services:

• OpenAI
• Eleven Labs

🚀 Getting Started

Follow these steps to get the app up and running! 🏃‍♀️

1️⃣ Clone the Repository

Clone this repository to your local machine:

git clone https://github.com/brayanjeshua/chatgpt-to-speech.git
cd chatgpt-to-speech

2️⃣ Install Dependencies Install the necessary dependencies:

npm install

3️⃣ Configure Environment Variables Create a .env file in the project root and populate it with your API keys:

touch .env

Then, open the .env file and add the following, replacing your_key_here with your actual keys:

.env

OPENAI_API_KEY=your_key_here
ELEVEN_API_KEY=your_key_here
VOICE_ID=your_voice_id_here
CHATGPT_MODEL=your_model_here

4️⃣ Run the Application Start your application:

node server.js

The server is now running at http://localhost:3000 🎉

You can now send a POST request to http://localhost:3000/chat with a JSON body containing a 'prompt' key. The server will return an audio file containing the AI's response!

Additionally you can set the temperature and the modality

5️⃣ Example: You can use curl to test the API:

curl -X POST -H "Content-Type: application/json" -d '{"modality":"Be ironic and acid in a short response", "prompt":"Hello, world!", "temperature":0.9 }' http://localhost:3000/chat --output response.mp3

This command will download a response.mp3 file with the response from GPT-4 converted to speech! 🗣️🎶
