  • Patent number: 10839789
    Abstract: An acoustic coprocessor is provided. The acoustic coprocessor may include an interface for receiving at least one feature vector and a calculating apparatus for calculating distances indicating the similarity between the at least one feature vector and at least one acoustic state of an acoustic model read from an acoustic model memory. The acoustic coprocessor may also include an interface for sending at least one distance calculated by the calculating apparatus.

  • Patent number: 9509545
    Abstract: A method at a mobile device, the method comprising: receiving one or more data symbols; determining reduced symbols for each of the data symbols, the reduced symbols corresponding to each of at least two orthogonal components of the data symbols; and, storing the reduced symbols in a symbol buffer.

  • Patent number: 9425826
    Abstract: A method of generating an interleaved symbol sequence location from a symbol location of a symbol sequence comprises determining the interleaved symbol location based on an interleaver sequence function which relates a linear symbol location to the interleaved symbol location. This is done by acquiring values of the interleaver sequence function in quotient and remainder form and then calculating the interleaved symbol location by performing operations of the interleaver sequence function in quotient and remainder form.

  • Patent number: 9076441
    Abstract: A speech recognition circuit comprising a circuit for providing state identifiers which identify states corresponding to nodes or groups of adjacent nodes in a lexical tree, and for providing scores corresponding to said state identifiers, the lexical tree comprising a model of words; a memory structure for receiving and storing state identifiers identified by a node identifier identifying a node or group of adjacent nodes, said memory structure being adapted to allow lookup to identify particular state identifiers, reading of the scores corresponding to the state identifiers, and writing back of the scores to the memory structure after modification of the scores; an accumulator for receiving score updates corresponding to particular state identifiers from a score update generating circuit which generates the score updates using audio input, for receiving scores from the memory structure, and for modifying said scores by adding said score updates to said scores; and a selector circuit for selecting at least o
