Yeah, two ways, lol. I have a big mic button on the bottom that I hold to speak, but I also type into an input field rather than the terminal and can use the mic on the phone keyboard.

FUTO has a superb Android keyboard with on-device voice transcription using a fine-tuned Whisper model, which is quite performant for me (and actually does fairly impressive text autocorrect and prediction too): https://keyboard.futo.org/

They also do a pure play voice input keyboard, if that's your jam or you want to use it with other keuboards: https://voiceinput.futo.org/

You could always just use whisper as a keyboard on the phone: https://github.com/woheller69/whisperIME
