Colab runs it in your browser. If it calls a model provider, it asks for that provider's API key in a cell.
How it works
You add a computed column that converts text to audio. The audio is cached and only regenerated when the source text changes.
What it covers
- Generate speech with OpenAI TTS
- Choose from multiple voice options
- Store text and audio together
