Filed:
Jul 27, 2012
Appl. No.:
13/560254
Inventors:
Nicolas Scheffer - San Francisco CA, US
Yun Lei - Palo Alto CA, US
Douglas A. Bercow - Menlo Park CA, US
Assignee:
SRI INTERNATIONAL - Menlo Park CA
International Classification:
G10L 15/00
US Classification:
704236, 704E15001
Abstract:
A system and method of verifying the identity of an authorized user in an authorized user group through a voice user interface for enabling secure access to one or more services via a mobile device includes receiving first voice information from a speaker through the voice user interface of the mobile device, calculating a confidence score based on a comparison of the first voice information with a stored voice model associated with the authorized user and specific to the authorized user, interpreting the first voice information as a specific service request, identifying a minimum confidence score for initiating the specific service request, determining whether or not the confidence score exceeds the minimum confidence score, and initiating the specific service request if the confidence score exceeds the minimum confidence score.

US Patent:
20190197187, Jun 27, 2019
Filed:
Dec 27, 2017
Appl. No.:
15/855521
Inventors:
- Menlo Park CA, US
Yun Lei - San Francisco CA, US
International Classification:
G06F 17/30
G06Q 50/00
G06N 3/08
Abstract:
In one embodiment, a method includes receiving a video file. The video file includes a corresponding audio stream. The method further includes accessing the audio stream, and generating, based on the audio stream, a representative vector. The vector has a particular number of dimensions. The method further includes accessing a label-embedding space, which has the same particular number of dimensions, and includes a number of regions that each correspond to a respective label. The method further includes determining a region of the label-embedding space that corresponds to the vector, the determined region corresponding to a particular label. The method further includes associating the particular label with the video file.
