FAQ

Speech & Audio, answered

35+ languages, including rare and low-resource ones, recorded by native speakers who capture regional dialect and natural code-switching. Because the speakers live in the language, the data reflects real pronunciation and mixed-language speech rather than a studio approximation of it.
