Fish Agent
An end-to-end (e2e) Voice Language Model by Fish Audio.
What is Fish Agent?
Fish Agent is the kind of voice cloning tool that lets you have natural-sounding voice conversations, almost like talking to a person. It's built by Fish Audio and does something pretty impressive: you can generate voice responses from text you type or even from your own speech.
Honestly, it's perfect for anyone who wants to create engaging voice content, test out different vocal styles, or just have a bit of fun mimicking conversational flows. Imagine wanting to prototype how a character in a story would sound or check the pacing of a dialogue—Fish Agent makes that surprisingly accessible.
Key Features
• Real-time voice response based on text input – Just type something, and it'll speak back to you with a generated voice that feels authentic. Great for writers or content creators.
• Speech-initiated prompting – You can literally start with your own voice, record yourself asking a question, and have the agent generate a voice answer. This two-way flow is genuinely exciting if you're into making your projects more interactive.
• End-to-end AI voice creation – The entire process from your input to the realistic voice output is handled smoothly, so you don't need to piece together separate tools—it's all wrapped up in one tidy model.
• Flexibility for different conversational tones – Want a voice that sounds serious for a documentary? Cheerful for an explainer video? The model adapts based on context, giving you options to play around with.
• Quick iteration for voice-based projects – Whether you're working in education, storytelling, or voice-over, you'll love how you can test different vocal responses without spending hours editing.
How to use Fish Agent?
-
Open the application and decide how you want to give your initial prompt—you can type your input as text or use your microphone to speak directly into the tool.
-
If you're starting with text: in the designated text box, write whatever you'd like the agent's voice to say or respond to, say, "Explain how this works in a friendly tone." If you prefer using your voice, just hit the record button and say your question aloud.
-
The AI processes your input—giving it a moment to interpret the context, tone, and intent behind your words. It then uses the Fish Audio model to choose the most fitting vocal style for the answer.
-
Almost instantly, you'll hear the voice model generate a spoken response that matches your original input, whether you started with text or speech.
-
If you're building a longer dialogue or testing multiple voice outputs, you can keep the conversation going by repeating the steps: just type another prompt or speak again to follow up and refine the voice replies. Pretty intuitive, right?
Some pro-tips from using it myself: start with short, clear prompts to get familiar with the voice behavior, and don't hesitate to play with emotional words in your text—it helps the AI adjust the delivery tone. And yeah, using the speech input mode can feel surprisingly natural, especially if you're crafting dialogue between multiple personas.
Frequently Asked Questions
Can I change the accent or gender of the voice that replies?
Fish Agent's model automatically tunes the voice based on your input and context—it doesn't have preset accent or gender controls built into the UI. Instead, you can hint at these aspects in your text prompt, like "Answer in a deep, male-sounding voice."
Is it possible to train a custom voice for my own character?
It primarily uses its pre-trained voice language model, so there's no personal voice upload for full customization. The cool part is you influence the style through the content you input—nuances in your words steer the emotional range and vocal dynamics.
How accurate is the emotion in the generated speech?
It's pretty good—I've seen it handle excitement, formality, and curiosity rather convincingly. Still, for very specific or niche emotions, you may need to refine your prompts a bit.
What languages can the voice model speak in?
Currently, the base model supports widely spoken languages, especially English, but you should try some phrases in another language to test it; the architecture does pick up multilingual inputs in practice.
Why would I use Fish Agent for content creation?
Content creators love how it saves time brainstorming voice directions—instead of hiring voice actors for drafts, you can quickly generate and listen to a few options.
Is there integration with other software I use daily?
While the core interface is standalone, it's designed to let you export outputs like audio files, which you can plug into common media and editing software.
Do I need a powerful device to run this smoothly?
Because it's an end-to-end model hosted online, you're mostly just tapping into Fish Audio's servers—so even a standard laptop and decent Wi-Fi are enough to use it.
How natural do conversations sound compared to other tools?
The responses tend to feel fluid and connected—not too robotic. It really shines on follow-up exchanges where each new AI reply considers your latest message. Honestly, if you give it clear, complete inputs, the conversation flow feels quite realistic.
