Fish Audio

Fish Audio is a strong choice if you want voice cloning with more control over expression than a basic text-to-speech service provides. Its short-reference cloning, multilingual S2.1 Pro model, direction tags and developer APIs make it useful for both content production and real-time applications.

The main catch is that the free options aren't identical. The creator Free plan has 8,000 monthly credits and limited generation time, while the free S2.1 Pro API is intended for development and can have commercial restrictions. Paid API usage starts at $15 per 1 million UTF-8 bytes, so production teams should calculate their expected text volume before choosing a plan.

Fish Audio is also seeing strong current interest. Its site says more than 8 million users have used its models, and recent community posts show developers using its cloning API in voice-agent projects.

Fish Audio is a voice AI platform for creating expressive speech, cloning voices and adding realistic audio to content or applications. It combines a web-based creator workspace with developer APIs for text to speech, voice cloning and speech recognition.

The current S2.1 Pro model is the main attraction. Fish Audio says it supports 83 languages, short-reference voice cloning, real-time generation and natural language controls for emotion, pacing and delivery. The API supports REST and WebSocket connections along with official Python and TypeScript SDKs.

For creators, Fish Audio also provides a large community voice library with more than 2 million voices, plus tools for video voiceovers, audiobooks and character voices. Developers can use the API instead, while eligible enterprise customers can arrange self-hosted deployments for environments that require more control over data and infrastructure.
