Fish Audio

What is Fish Audio?

Fish Audio delivers real-time text-to-speech with emotion control and voice cloning, helping creators and developers generate spoken audio from text. It’s designed for producing voiceovers and character voices for creators, developers, and teams, including workflows that range from live-style avatars to studio-quality narration.

The platform combines voice generation with controllable speaking styles (via emotion and special tags) and a voice library that includes many sample voices. It also includes pro audio tools and an API option for fine-tuning cloned voices and dynamic emotion online.

Key Features

• Text to Speech with emotion tags: Generate audio from your own text and steer delivery using predefined emotion categories (e.g., angry, sad, whispering, excited) and special performance tags.
• Voice cloning: Create a voice that sounds like a specific speaker (“voice cloning that sounds just like you”) and use it to produce consistent character and brand persona audio.
• Speech-to-text: Convert spoken content into text using the platform’s built-in speech-to-text capability.
• Voice library (2M+ voices): Access a large voice library and select from many available voices for generation.
• Pro audio tools: Use additional audio production tools alongside generation for studio-quality output.
• API support for dynamic emotions: Fine-tune voice behavior and dynamic emotions through an easy-to-use API (for developers building custom experiences).

How to Use Fish Audio

1. Start a generation from the text input area (choose Text To Speech, or use voice cloning to work with an existing voice).
2. Enter your text and select a voice.
3. Add emotion/special tags to control how the output is performed.
4. Generate and play the audio, then use the provided tools to refine the result.
5. If you’re building an app or integration, use the API to connect the generation workflow to your product.

Use Cases

• Video voiceovers for creators: Turn scripts into narration for YouTube, advertisements, and explainers by swapping tones and adding emotion tags that match scenes.
• Audiobook narration at chapter granularity: Produce publish-ready storytelling with controllable pacing and emotion, generating long-form audio without relying on a recording booth.
• Character voices for games and animation: Clone a signature voice or create a brand persona for interactive stories, then vary emotional delivery.
• Conversational customer support and virtual agents: Generate natural-sounding responses with minimal latency and use tone/emotion tags for empathetic or upbeat interactions.
• Speech-to-text workflows: Convert spoken content into text using the platform’s speech-to-text feature.

FAQ

• What does Fish Audio generate? Fish Audio generates spoken audio from text (text-to-speech) and supports voice cloning to produce output in a chosen speaker’s voice.

• How do emotion and speaking style controls work? During generation, you can apply emotion tags (e.g., angry, sad, whispering, excited) and special performance tags (e.g., laughing, sighing, long pause) to control delivery.

• Does Fish Audio support both text-to-speech and speech-to-text? Yes. The page lists Text To Speech and Speech To Text.

• Can developers integrate Fish Audio into their applications? The page states there is an API and that dynamic emotions can be fine-tuned through it.

• How large is the voice library? The page mentions a Voice Library with 2,000,000+ voices.

Alternatives

• General text-to-speech platforms: Use when you primarily need speech generation from text with basic prosody controls, without the same emphasis on voice cloning and fine-grained emotion tagging.
• Voice cloning services: Consider when your top priority is replicating a specific voice; workflows may focus more heavily on cloning setup than on integrated emotion-tagged narration.
• AI audio production toolkits: Useful if you want a broader studio workflow for editing and post-processing, while relying on separate generation tools for text-to-speech.
• Developer-focused speech SDKs/APIs: Suitable when building custom products that need programmatic speech features; may differ in how emotion control and cloning are exposed via API.
