From the application.
For example, one or more voice processing algorithms to determine whether a user has a sore throat may be selected for use on the voice data 136 based at least in part on the detection of the cough and/or the sniffle from the user.
Any number of voice processing algorithms and/or signal processing profiles may be selected and applied to the voice data 136 to determine the user's physical or emotional condition. P
reliminary determinations, such as detections of a cough or other feature, may be made at the voice interaction device 110 in some embodiments.
A current physical and/or emotional condition of the user may facilitate the ability to provide highly targeted audio content,
such as audio advertisements or promotions, to the user 130.
