  • Patent number: 10971140
    Abstract: A speech recognition circuit comprises an input buffer for receiving processed speech parameters. A lexical memory contains lexical data for word recognition. The lexical data comprises a plurality of lexical tree data structures. Each lexical tree data structure comprises a model of words having common prefix components. An initial component of each lexical tree structure is unique. A plurality of lexical tree processors are connected in parallel to the input buffer for processing the speech parameters in parallel to perform parallel lexical tree processing for word recognition by accessing the lexical data in the lexical memory. A results memory is connected to the lexical tree processors for storing processing results from the lexical tree processors and lexical tree identifiers to identify lexical trees to be processed by the lexical tree processors.

  • 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.
