Text-to-Voice Design

Describe the voice you want — age, gender, tone, emotion — and AI generates matching speech instantly.

Voice Cloning

Upload an audio clip or record your voice directly, then clone the speaker's voice. Provide a transcript for even higher quality.

Browser Audio Trimming

Select exactly which part of your audio to use with the built-in waveform trimmer. No external tools needed.

How to Use

1. Choose a Mode

Select "Text Instruction" to design a voice from a text description, or "Voice Cloning" to replicate a voice from an audio file.

2. Configure Your Input

For Text Instruction, describe the voice style (e.g. "calm male narrator"). For Voice Cloning, upload an audio file or record your voice, and optionally enter its transcript.

3. Enter Text to Read

Type the text you want spoken in the generated voice. The AI supports multiple languages including English, Japanese, Chinese, and more.

4. Generate & Download

Click "Generate" and wait a few seconds. The generated audio will appear as a player you can listen to and download.

Two Modes Explained

Text Instruction Mode

Design a completely new voice using natural language. Describe characteristics like "A warm, deep male voice with a storytelling tone" and the AI creates a matching voice from scratch. Great for narration, announcements, and creative projects.

Voice Cloning Mode

Clone an existing voice from a short audio sample (3–15 seconds). Upload a file or record directly from your microphone. For best results, provide a transcript of what's spoken in the reference audio. If you skip the transcript, the AI uses speaker embedding only — quick but slightly lower quality.

About AI Voice Synthesis

AI voice synthesis (text-to-speech) technology has advanced dramatically, enabling the generation of natural, human-like speech from text. Modern models can capture nuances of intonation, emotion, and speaking style that were previously impossible to reproduce artificially.

Voice cloning takes this further by allowing the replication of a specific person's voice from just a few seconds of audio. This opens up applications in content creation, accessibility, game development, and personalized voice assistants.

Fire Lit AI's Voice Design tool is powered by Qwen3-TTS, a state-of-the-art multilingual text-to-speech model. It runs entirely in the cloud with no software installation required — just open your browser and start generating.
