The AI Audio Landscape
From the course AI for Audio: Music, Voice & Sound
AI has transformed every aspect of audio — from generating music and speech to transcribing and translating spoken language. Understanding the landscape helps you choose the right tool for each task.
The Four Pillars of AI Audio
- Text-to-Speech (TTS) — Converting written text into natural-sounding speech
- Speech-to-Text (STT) — Transcribing spoken audio into written text
- Music Generation — Creating original music from text descriptions
- Voice Cloning — Replicating a specific voice for custom speech generation
