Fish Audio S1
Expressive Voice Cloning and Text-to-Speech
Visit website →About
Fish Audio S1 is a text-to-speech and voice-cloning model built for expressive, emotionally aware narration rather than flat robotic reads. It reproduces rhythm, emphasis, and mood, and can shift tone within a single passage.
Voice cloning needs about ten seconds of reference audio and keeps the speaker's accent, timbre, and speaking habits. The model handles multiple languages and is available through a web playground and a developer API for apps, dubbing, audiobooks, and agent voices.
It suits podcasters, video producers, game studios, and developers who need natural voice output at scale. Pricing is usage-based with a free allowance, and cloned voices can be kept private to an account.

Why we picked it
Fish Audio S1 made the list for cloning from just ten seconds of reference audio while keeping accent and timbre intact — a notably low bar for input compared to most cloning tools, and the mid-passage tone shifting is worth naming for anyone narrating something emotionally varied.
