| | 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 |
