# 🔥 FireRedTTS3
Interactive demo of [FireRedTeam/FireRedTTS3](https://huggingface.co/FireRedTeam/FireRedTTS3),
a unified speech generation and editing model (Qwen3-1.7B backbone + flow-matching
head over the continuous RedAE audio autoencoder, 24 kHz).
Three tabs:
| Tab | Checkpoint | What it does |
| --- | --- | --- |
| 🎙️ Voice Cloning | `fireredtts3_base` | Zero-shot cloning from a short reference clip — 24 languages and 21 Chinese dialects |
| 🎨 Voice Design | `fireredtts3_instruct` | Creates a voice from a natural-language description, no reference audio |
| ✂️ Speech Editing | `fireredtts3_instruct` | Semantic edits (insert / delete / substitute words) and acoustic edits (speed, pitch, volume) |
Text normalization runs locally via `wetext` (Chinese / English); automatic language
routing uses fastText `lid.176`. The optional LLM-based normalizer from the upstream
repo is disabled here (it requires external API credentials).
