IIRC every browser that supports the Web Speech API does so via cloud services. Mozilla being the only major browser engine maker without it's own "cloud" and having slightly fewer phone-home features than many of the others didn't want to do that. Mozilla has been doing quite a bit of work in the area though (for example https://github.com/mozilla/DeepSpeech https://github.com/mozilla/DeepSpeech), hopefully to enable these features locally in the future. IMO it's good if we don't make web platform features unfeasible to implement locally, so I think mozillas stance makes sense. A new browser should not have to have the backing of a massive cloud provider willing to give away compute for free.
