maybe... Google doesn't support smaller languages for STT.
My other gripe with these tools is if there is background noise, they are pretty useless. You can't use them in a crowded room.
In most noisy contexts, a throat microphone should work [1]. A small Bluetooth one could also connect to its small earpiece(s) to make a wearable speech interface whose bigger battery could be concealed in the mic and last much longer than usual earbuds.
When I usually need a translation app is when I am traveling. I can't just ask a stranger to tape a throat mic and wear my headphones to have a conversation with me though
