| This repository contains **Soprano-Encoder**, which converts raw audio into audio tokens that the LLM backbone can recognize. |
|
|
| ## Overview |
|
|
| **Soprano** is an ultra‑lightweight, on-device text‑to‑speech (TTS) model designed for expressive, high‑fidelity speech synthesis at unprecedented speed. Soprano was designed with the following features: |
| - Up to **2000x** real-time generation on GPU and **20x** real-time on CPU |
| - **Lossless streaming** with **<15 ms** latency on GPU, **<250 ms** on CPU |
| - **<1 GB** memory usage with a compact 80M parameter architecture |
| - **Infinite generation length** with automatic text splitting |
| - Highly expressive, crystal clear audio generation at **32kHz** |
| - Widespread support for CUDA, CPU, and MPS devices on Windows, Linux, and Mac |
| - Supports WebUI, CLI, and OpenAI-compatible endpoint for easy and production-ready inference |
