  • Rank-reduced token representation for automatic speech recognition
    Patent number: 10593346
    Abstract: The present disclosure generally relates to processing speech or text using rank-reduced token representation. In one example process, speech input is received. A sequence of candidate words corresponding to the speech input is determined. The sequence of candidate words includes a current word and one or more previous words. A vector representation of the current word is determined from a set of trained parameters. A number of parameters in the set of trained parameters varies as a function of one or more linguistic characteristics of the current word. Using the vector representation of the current word, a probability of a next word given the current word and the one or more previous words is determined. A text representation of the speech input is displayed based on the determined probability.

  • Navigation system with location adaptation and method of operation thereof
    Patent number: 8483959
    Abstract: A method of operation of a navigation system includes: receiving a request for a destination; establishing a predetermined time period based on the destination; calculating a user generated address associated with the destination and filtered with the predetermined time period; generating a comparison between a destination address of the destination and the user generated address; and generating a travel route to the user generated address for the destination with the comparison as the non-match for displaying on a device.
