## What is it?

On-device speech models for Dictation, Siri and other speech features, one per language, kept in a protected system folder so speech can be recognised without a network connection.

## What happens if you delete it?

macOS downloads a model again whenever its language is enabled for dictation or Siri.

## How to remove it properly

Do not delete them by hand. Remove dictation languages you no longer use in System Settings › Keyboard › Dictation, so macOS can drop their models.
