Does Win Phone 8 use internet for speech recognition?

Question

Windows phone

Question for Windows Phone 8 users. There is such a wonderful feature as voice control of the phone. Does this feature need internet? Does voice recognition happen locally or is it sent to a Microsoft server?

Answer 1

The official documentation says that you can additionally agree to send data to the Internet:

When you first start Speech, we ask you if you want to enable the speech recognition service. If you accept, the words you speak and supporting data, including recent contact names, will be sent to Microsoft to provide and improve the service.

I agreed, and, subjectively, the accuracy of recognition became amazing.

Answer 2

I just checked on the emulator, the Note command without the Internet was executed by Call and I can’t check the Russian language, although I recently held wp8, called the subscriber. There was definitely no 3G on the device, but I'm not sure about Wi-Fi

Answer 3

Yes maybe. Works even in an elevator, where neither WiFi nor GSM signals penetrate.
As for the transfer of data and speech to the server, I think the point is that during the time of recognizing a phrase on a relatively weak phone hardware, the Microsoft online service manages (or does not have time) to give out its assumption, which is used in correcting the final hypothesis. Although, I'm not a speech recognition expert.

Answer 4

Checked on a live phone. WP8 Switched it to the "on the plane" mode - speech recognition works fine, including on tricky surnames like "call Landensman" :)
Conclusion - the Internet is not needed.
Does anyone know if SMST can be taught to recognize and write from a voice?
