## What it is
Mozilla Common Voice is a web platform for crowdsourcing voice donations to build public-domain speech datasets for training voice recognition tools. This repository contains the web application code for the platform.

## Use cases
- collect voice recordings from contributors to build speech datasets
- create public domain datasets for training speech recognition models
- add a new language to a crowdsourced voice dataset platform
- self-host a voice donation collection platform
- find multilingual speech data for machine learning

## When to choose
- you need large-scale, openly licensed speech data across many languages
- you want to run or contribute to a crowdsourced voice collection platform

## When to avoid
- you need a ready-to-use speech recognition engine rather than training data
- you need proprietary or commercially licensed voice datasets

## Facets
- artifact type: application
