How to kickstart OpenAI text to speech: Python quick tutorial

Getting started with OpenAI text to speech is quick and easy, especially for developers. Using the API or demo, you can convert text into lifelike audio effortlessly. Follow these simple steps to create high-quality voiceovers in no time.

Steps to using OpenAI's text-to-speech in the most efficient way

STEP 1
1. Generate your OpenAI API key and set up the environment

To begin, log in to your OpenAI account and navigate to the API Keys section. Click Create new secret key, name it (e.g., tts-example), and store the key securely, as it won't be shown again. Next, create a virtual environment to manage dependencies separately using the command python -m venv venv. Activate the environment using source venv/bin/activate (Mac/Linux) or venv\Scripts\activate (Windows). Finally, install the required libraries by running pip install openai python-dotenv to enable API access and secure key storage.

STEP 2
1. Write the Python code to generate speech

Now, create a new Python file (main.py) and import necessary libraries, including openai, dotenv, and pathlib. Load your API key from the .env file using load_dotenv() and retrieve it with os.getenv("SECRET_KEY"). Initialize the OpenAI client and use client.audio.speech.create() to generate speech from a text input. Set parameters such as model="tts-1", voice="alloy", and your desired input text. Finally, save the generated audio as an MP3 file (speech.mp3) in the script's directory for easy access.

STEP 3
1. Run the program and download your audio

Execute the script by running python main.py in your terminal or command prompt. The OpenAI API processes the request, converts the input text into speech, and generates an MP3 file. Once completed, the script saves the file in your project directory under the name speech.mp3. You can now locate and play the file using any media player to verify the output. If needed, adjust text input, voice type, or model settings to customize the speech output.
