Fish Speech 1.5’s voice cloning technology is blazing fast! It can synthesize a voice with less than 150ms latency, which is practically real-time.
All you need is a 10 to 30 second voice sample, and it can replicate that voice with high fidelity.

- Create personalized voice guides or navigation systems that don’t sound generic.
This one’s impressive! Whether you’re working with English, Chinese, or structurally complex Arabic, Fish Speech 1.5 handles it all. Unlike traditional systems, it doesn’t require phoneme conversion before generating speech.
What does that mean? It means strong generalization and significantly easier support for new languages—this is a big leap forward for TTS technology!

All talk and no data? Not here. Fish Speech 1.5 boasts an English word error rate as low as 2% (based on a 5-minute article)—super impressive accuracy!
And the speed? With an Nvidia RTX 4060, the real-time factor (RTF) hits 1:5 (i.e., generating 1 second of audio only takes 0.2 seconds); with an RTX 4090, it reaches a blazing 1:15!
Key metrics:
