## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 2771, "days_push": 818, "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
A curated list of open and accessible speech corpora for ASR, TTS, and other speech technologies, organized by license (e.g., CC-0). It catalogs datasets with languages, hours, speaker counts, download links, and licenses.

## Use cases
- find free speech datasets for training a TTS model
- locate open ASR training corpora for a specific language
- find multilingual speech data like Common Voice for speech recognition research
- source single-speaker datasets for voice cloning experiments
- compare speech corpora by license, hours, and speaker count
- find datasets for speech emotion recognition or voice activity detection

## When to choose
- you need to discover open-licensed speech datasets for research or commercial use
- you want a curated catalog with download links and license details rather than raw data

## When to avoid
- you need the actual audio data itself rather than links to it
- you need a tool or library for processing speech rather than a dataset list

## Facets
- artifact type: dataset
- maturity: maintenance
- function: speech-recognition, tts, nlp, audio-processing
- domain: speech-processing, machine-learning, awesome-lists
- platform: cross-platform
- tags: speech-corpora, asr, dataset-catalog, curated-list, open-data, natural-language-processing
