Dictum vs FUTO Voice Input

FUTO Voice Input is a free, open-source offline speech-to-text for Android that plugs into compatible keyboards. If you want free and are comfortable configuring it, it is a good choice.

Dictum (pre-release) aims at people who want a ready-to-use voice keyboard with text clean-up, recording and transcripts, and a verifiable privacy model, for a single payment.
