Thank you for bringing this up.

Indeed Common Voice is not for everyone. We try to make it clear in our Privacy Policy [1] what pieces of data we collect and why. We do not publish email address or names with the data, and we even strip speaker identification info (so that a speaker's recordings are not grouped but instead everyone's recordings go into one giant bucket). That said, if this still makes you feel uncomfortable, we understand. And if you would like to contribute without donating your voice, you can always validate the recordings of others.

I won't contribute because speech interfaces are imo terrible and against the proliferation of Echo and Duplex like services, but the data collected is listed here

speech interfaces are developed by large corporations and there is nothing you can do about that. With Common Voice you are helping to create open-source alternative, which is a positive thing, I guess

Speech interfaces have some limited usecases where they are much better than alternatives. For example in situations where you need your hands for something else, like in a car.
