Specifies whether the device will receive updates to the speech recognition and speech synthesis models.

A speech model contains data used by the speech engine to convert audio to text (or vice-versa). The models are periodically updated to improve accuracy and performance. Models are non-executable data files.

If enabled (default), the device will periodically check for updated speech models and then download them from a Microsoft service using the Background Internet Transfer Service (BITS).
