## Health v2 (maintenance only)
Score: 29/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 13, release rhythm 8, longevity 100
- inputs: {"age_days": 1623, "days_push": 526, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Mimic 3 is a fast, local neural text-to-speech engine developed by Mycroft for the Mark II voice assistant, usable as a Python library, CLI tool, or Dockerized HTTP server. The project is no longer actively maintained; Piper TTS is its recommended successor.

## Use cases
- convert text to speech locally without cloud services
- add offline TTS to a voice assistant
- run a text-to-speech HTTP server in docker
- synthesize speech from the command line
- generate spoken audio for embedded or low-resource devices
- self-host a neural TTS API

## When to choose
- you need fully offline, fast neural TTS on modest hardware
- you are integrating with Mycroft or a similar voice assistant
- you want a simple CLI or HTTP API for speech synthesis

## When to avoid
- you are starting a new project - use Piper TTS instead
- you need actively maintained software with bug fixes
- you need the latest voice quality or language coverage

## Facets
- artifact type: library
- maturity: abandoned
- function: tts, speech-recognition, http-server, cli
- domain: speech-processing, artificial-intelligence, developer-tools
- platform: python, cross-platform, cli, self-hosted
- tags: text-to-speech, neural-tts, voice-assistant, offline, mycroft, deprecated, docker, linux
