Hello,
Part of the efforts of the community support desk is the activation stage, once a language in CV has enough data to train a usable STT model, then the language should go live on one of the major platforms at least.
In this light, there are Firefox Android, Firefox OS and Firefox Reality (deprecated). Looking at Firefox Android, it supports several search engines, the one that seems to support search by voice is Google, it’s also open to add new search engines. For endangered and vulnerable languages, this could be the lifering for them.
What do you think of this idea? If it is interesting enough, how can we realize it? (I think this can be officially supported by Mozilla or a community extension.)
Here is a screenshot for Firefox Android search settings:
