Keyspoken / Offline dictation that works in airplane mode

Offline dictation that works in airplane mode

Keyspoken is offline speech to text for iPhone. After a one-time model download it works without internet, uses no data and sends no audio anywhere.

How it works offline

Keyspoken runs its speech model on your iPhone itself. Once the model is on the phone, turning voice to text needs no connection at all: not Wi-Fi, not mobile data. It works in airplane mode, on a plane, underground or abroad.

The one thing that needs a connection

The speech model is downloaded once, when you set the app up. The English model is about 440 MB. The app tells you the size first and can wait for Wi-Fi. After that, nothing.

Why offline matters

  • It works where the signal doesn't.
  • It uses none of your data allowance.
  • There is no server to be slow, busy or down.
  • Your audio has nowhere to go, because nothing is sent.

Does the iPhone's built-in dictation work offline?

For many languages, yes. Apple says dictation is processed on the iPhone in many languages and needs no internet connection. Dictating into a search field is different: the text may be sent to the search engine.

Keyspoken works the same way for every language it supports: once the model is on the phone, nothing is sent anywhere.

What you trade for it

An offline model lives on your phone, so it takes storage: about 440 MB for English. That is the whole cost.

Questions

Does voice to text use data?

It depends on the app. Keyspoken uses no data to transcribe, because the speech model runs on your iPhone. The only download is the model itself, once, at setup.

Can I dictate without internet on iPhone?

Yes. Keyspoken transcribes on the device, so it works with no connection once its model is downloaded.

Does iPhone dictation work in airplane mode?

For many languages, yes. Apple says built-in dictation is processed on the iPhone in many languages with no internet connection. Keyspoken also works in airplane mode once its speech model is downloaded.

Do both voice models work offline?

Yes. The English model and the multilingual model both run on the device.
