Common Voice – Mozilla's initiative to help teach machines how real people speak
It's going to be tricky.I did some of the "listen" exercises to validate how people pronounced some sentences, and I got a few people who spoke with very strong (Indian, Nigerian, UK, ...) accents. How would you take these things into account? Just average all of them and hope for the best? Not sure how to approach that. I don't think it's very straight-forward. Interesting problem though.However, you can't do anything if you don't even have the data, so props to Mozilla for starting this.
