Africa has 2,000+ languages.AI understands almost none.

Echo helps African organizations and communities build the native voice datasets AI has been missing.

The Problem.

2,000+

African languages

< 20

have usable AI voice data

1B+

speakers excluded from voice AI

Our Solution.

A platform for collecting, reviewing, and exporting voice data in African languages. Organizations create campaigns, communities record, and you get a clean dataset.

Campaign creation

Upload your sentence list and configure your campaign in minutes.

Browser recording

Contributors record directly in their browser. No apps needed.

Built-in QA review

Every recording reviewed by a human before it enters your dataset.

Export-ready datasets

Download in Common Voice format. Reviewed, licensed, ready to train.

For communities. For the teams that need them.

For language communities

Your language has been excluded from AI long enough.

  • Record in your language, directly in your browser
  • Every submission is reviewed before it counts
  • See your language represented in AI for the first time
  • Earn recognition for every approved recording

For organizations and AI teams

Get the datasets you need without building the collection infrastructure.

  • Create campaigns in any African language or dialect
  • Consent flow and QA review built in
  • Datasets export in Common Voice format, ready to train
  • Commission exactly the data your model needs

How it will work.

01

Set up a campaign

Organizations upload a sentence list, set the language and dialect, and configure consent terms. The campaign goes live.

02

Community records, reviewers check

Contributors record through their browser. Every submission is reviewed. Approved recordings count, rejected ones return to the pool.

03

Export a dataset you can trust

Download WAV files and full metadata in Common Voice format. Every recording in the export was human-reviewed.
