A system pattern-based speech recognition, e.g., a hidden Markov model (HMM) based speech recognizer using Viterbi scoring. The principle of minimum recognition error rate is applied by the present invention using discriminative training. Various issues related to the special structure of HMMs are presented. Parameter update expressions for HMMs are provided.read more

Patent
Automated Response to and Sensing of User Activity in Portable Devices
TL;DR: In this paper, various methods and devices described herein relate to devices which, in at least certain embodiments, may include one or more sensors for providing data relating to user activity and at least one processor for causing the device to respond based on the user activity which was determined, at least in part, through the sensors.
Patent
Using context information to facilitate processing of commands in a virtual assistant
TL;DR: In this article, a virtual assistant uses context information to supplement natural language or gestural input from a user, which helps to clarify the user's intent and reduce the number of candidate interpretations of user's input, and reduces the need for the user to provide excessive clarification input.

Rapidly training a speech recognizer to a subsequent speaker given training data of a reference speaker
TL;DR: In this article, label output probabilities for subsequent speakers are re-parameterized based on confusion matrix entries having values indicative of the similarity between an lth label output of the subsequent speaker and a kth output for the reference speaker.

Method of optimizing a composite speech recognition expert
TL;DR: In this article, a method for adjusting the relative weighting to be applied to those scores employing training data utilizing the words to be recognized in multiple word phrases is disclosed, where multiple word test phrases are applied to the acoustic expert to determine, for each phrase, plural multi-word hypotheses each having corresponding cumulative scores.
