About free voice AI courses for students
These free courses teach the building blocks of voice AI: speech-to-text, text-to-speech and the voice agents that combine them with an LLM. Start with the Hugging Face Audio Course if you're new — it covers transformers for audio and ends with a voice-assistant project. If you already know some Python, the DeepLearning.AI short courses walk you through building and deploying a real-time voice agent in about an hour each. Every course here is free to take, and each card links to the official course page.
Learn voice AI — FAQ
What's the best free course to learn speech recognition?+
