Woodstitch LLC  ·  Colorado, United States

Woodstitch is a human-evaluation platform for speech AI: paid listeners judge audio in blinded studies, and the results are published as research or returned to clients through an API. Everything below reaches a person.

1. Support

Raters (payments, account, a clip that would not play): support@woodstitch.com. Please include the email address you sign in with.

API clients (keys, quotes, a study that is not progressing, billing): support@woodstitch.com with your evaluation id. The API documentation and rate card answer most questions first.

2. Research, data and press

Requests for the per-judgment data behind a published study, questions about a method, corrections, or a request to be notified when a study is updated: support@woodstitch.com, naming the study. Each report's data section says what is available. Press and interview requests go to the same address.

3. Run a study

If you make or buy text-to-speech and want listeners to judge it, start at Human evaluation for text-to-speech. The first step prices a study without charging anything.

4. Company

Woodstitch LLC is a Colorado limited liability company. It operates woodstitch.com, the rating platform and the client API, and publishes Woodstitch Research.
