To improve your device’s ability to correctly recognize your pronunciation and handwriting, Microsoft collects speech, inking, and typing information when you interact with your Windows device by speaking, writing, or typing. If you’ve allowed Cortana to do so, Microsoft also collects information about your Calendar and People (also known as contacts) to help personalize your experience and helps Cortana better recognize people, events, places, and music when you dictate messages or documents.
Whenever we collect data, even when it’s to make your device work better for you, we want to make sure you have all the information to make the right choices about how and when that data is used. That’s why we provide the info and controls described on this page.
To use voice input in Cortana, Getting to know you (the privacy setting for Speech, inking, and typing) must be turned on. This is because Cortana and speech services exist both in the cloud and on your device. And the info Microsoft collects from these services in turn helps to improve them. Speech services that don’t rely on the cloud and only live on your device, like Narrator and Windows Speech Recognition, will still work when this setting is turned off; but Microsoft won’t collect any speech data without your consent.
