Is voice recognition safe to use?

Voice recognition is safe to use when you know where the audio goes. On-device processing, which covers iPhone dictation in supported languages and Voice Control entirely, means your speech never leaves the phone. Cloud dictation sends audio to servers, which is where privacy policies start mattering.

Is iPhone Voice Control always listening? It listens locally while enabled, processes on-device, and uploads nothing; the battery cost is the honest downside, not surveillance.

Sensible rules: check whether a dictation tool processes locally or in the cloud, read what cloud vendors retain, and keep dictation of sensitive content, medical, legal, financial, on tools that state their handling plainly. Safety comes in degrees, and on-device sits at the calm end.

For the calm end, offline voice to text keeps every word on the device.
