## Health v2 (maintenance only)
Score: 44/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 62, release rhythm 35, longevity 19
- inputs: {"age_days": 276, "days_push": 230, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Soprano is an ultra-lightweight 80M-parameter text-to-speech model and Python library for fast, expressive, high-fidelity speech synthesis on CPU, CUDA, and MPS devices. It ships with a WebUI, CLI, OpenAI-compatible endpoint, ONNX export, and ComfyUI integration for both interactive and production inference.

## Use cases
- convert text to realistic speech audio on-device
- stream tts audio with low latency
- run fast text-to-speech on cpu without a gpu
- self-host an openai-compatible tts endpoint
- generate long-form narration with unlimited length
- fine-tune a custom voice model
- integrate tts into comfyui workflows

## When to choose
- you need fast, low-latency tts on cpu or edge hardware
- you want a small model under 1 GB memory footprint
- you need streaming speech generation with sub-250ms latency
- you want multiple inference interfaces (cli, webui, api, onnx)

## When to avoid
- you need the absolute highest fidelity from large state-of-the-art tts models
- you require many built-in languages or voices beyond what the model supports
- you need voice cloning out of the box without training your own model

## Facets
- artifact type: library
- maturity: active
- function: tts, speech-recognition, llm-inference, cli, http-server
- domain: speech-processing, machine-learning, artificial-intelligence
- platform: python, cross-platform, cli
- tags: text-to-speech, on-device, streaming-audio, onnx, openai-compatible-api, comfyui, lightweight-model, audio, cuda, gpu, web-server
