Can’t set up account

I’ve been trying to confirm my account, but seems impossible. I’ve tried everything I can think of to make it work, but this is all that comes up when I click the link emailed to me {"message":""} I made sure everything was done through the same browser. Then I tried with different email addresses and accounts on other browsers just in case it didn’t like my .edu email, or the browser I originally tried to set it up through, or whatever. Uninstalled the app then tried it all over again being very careful to do it right. But yeah, no success ☹️ What a bummer, this seemed like a way I could donate my time to help. I still would like to contribute, if anyone has figured out how to get it to work, or knows where I messed up, please let me know.

Fix the login process

It’s impossible to log in through the iOS app since the process relies on clicking a validation link that’s emailed to you, and the link cannot be opened inside of the embedded browser inside of the app. Instead, you just got logged in to Safari, which the platform doesn’t support to contribute to recordings. You can still contribute in the app anonymously, but what’s the fun in that?

Donate your voice for a good cause

The big companies that own speech recognition technology right now don't care about disabled users because they are a small fraction of their user base. But these users rely on this technology and have greater demands than anyone else. By contributing your voice to this effort, you will help build open source speech recognition that can be tailored to the people who need it most.
