Offline Voice Typing Keyboard

I made Sotto because I got tired of thumb-typing long messages I could have just said out loud. I wanted a voice typing keyboard that didn't send my voice anywhere, so that's what I built. It's a keyboard with a microphone key. You tap the mic and talk, and the words get typed into whatever app you've got open. A text, an email, a search bar, your notes, some form you're filling out at the doctor's office.

The speech to text part is done by your phone's own offline voice model (Android's on-device speech recognition). Sotto doesn't have servers and it doesn't upload anything. Once the offline voice language is downloaded on your phone, dictation works in airplane mode too, which I still think is kind of neat.

Which languages you can dictate in comes down to the offline voice languages your phone offers. There's an "Offline voice model" button in the app that opens your phone's voice input settings so you can add or update languages.

It's also just a normal keyboard with letters, numbers, symbols, shift, backspace and enter. The typing keys are a Latin QWERTY layout. If you write in another script, Sotto can still do the voice to text for you, but to type in that script you'd tap the globe key and switch to another keyboard. Not ideal, I know.

In settings you can turn on key preview, a number row and clipboard history. The clipboard only holds your last few copies in memory and never writes them to disk.

If you dictate in English, there's a switch that drops "um" and "uh" from what you say. That one is English only.

Setup happens inside the app: enable the keyboard, switch to Sotto, then allow the microphone.

About money. Typing is always free. Dictation is free for the first week, and after that it's a single in-app purchase to unlock it for good. I'm not doing a subscription. You don't need an account, and I don't show ads.
