AI Voice Designer
Describe a voice in plain words and get a synthetic voice ready to narrate anything.
No recording, no casting call. Write a short description — age, gender, tone, accent, pacing — and this tool invents a voice that matches. It lands in your presets with a sample clip, ready to read any script through Text to Speech. It runs on Fish Audio’s voice design model.
How to design a voice
- Write a brief describing the speaker, e.g. “Excited male product reviewer, mid-30s, fast-paced, high energy, and persuasive.”
- Generate. The model composes a voice and reads a short preview line so you can hear it immediately.
- Use the voice with Text to Speech to narrate any script.
Emotion control
The voice you design isn’t locked to one flat tone — direct its performance afterward with the same inline emotion tags used across Mitte’s Fish Audio tools:
-
Wrap an emotion in brackets before the words it should affect:
[happy],[sad],[excited],[whispering]. -
Combine tags and add intensity modifiers, like
[very excited]or[slightly nervous].
See the full tag reference on the node page for the complete list of 64+ emotions and delivery styles.
Writing a good brief
- Describe the person, not just a category. “Fast-paced, high energy, persuasive” gives the model more than “young man.”
- Anchor it in a context. “Late-night radio host”, “kids’ show narrator”, “luxury brand commercial” each pull the voice in a specific, useful direction.
- Pin the accent and pace if they matter: “slight Irish accent, measured pace” beats hoping for the best.
- One voice per brief. Describe a single speaker — contradictory traits (“booming whisper”) muddy the result.
What creatives use it for
- Character voices. Cast an entire animation or game from text: the gruff mentor, the nervous sidekick, the villain who whispers.
- Brand voices. Design a voice that fits the identity, use it across product videos, ads, and tutorials, and never worry about a voice actor’s availability.
- Narration without casting. Documentary, explainer, or audiobook narration matched to the material’s mood.
FAQ
How do I create a character voice with AI?
Describe the character — age, tone, accent, personality, context — and generate. The model invents a voice matching your brief; no actor or recording is needed.
What’s the difference between this and the Voice Cloner?
The Voice Cloner copies a real, existing voice from a recording. This tool invents a voice that doesn’t exist, from a text description alone. Use the Cloner when you have a real voice to preserve; use this when you’re inventing a new one.
Can I control emotion in the designed voice?
Yes — once designed, direct it the same way as any Fish Audio voice: wrap emotions in brackets in your script, like [excited] or [sad][whispering], when you generate speech with Text to Speech.
