Fish Audio gives its voice AI away, and charges for the latency

Fish Audio, a Palo Alto voice AI startup, raised $52m seed funding while offering open-source voice models for free and charging enterprises for latency and uptime guarantees. Its models support 83 languages, clone voices from short clips, and have gained over 8 million users and $21m annual revenue. The company relies on a large user-supplied voice library but faces challenges with unauthorized voice uploads and slow takedown processes.
