Abstract:
1. A computer-implemented method for speech recognition, the computer-implemented method comprising: transmitting a spoken query to a server computer, the spoken query recorded via a client device, the spoken query recorded as input of a geographical navigation system, the geographical navigation system including a geographical navigation database that maintains point-of-interest locations; receiving, from the server computer, multiple speech recognition hypotheses of the spoken query, the multiple speech recognition hypotheses generated by a first automated speech recognition process that analyzed the spoken query as a Chinese language spoken utterance; executing a second automated speech recognition process on the spoken query based on the multiple speech recognition hypotheses received; updating the multiple speech recognition hypotheses based on speech recognition results from the second automated speech recognition process; converting the multiple speech recognition hypotheses to respective Pinyin strings; searching the geographical navigation database with each respective Pinyin string using a fuzzy matching process, the fuzzy matching process identifying a list of N-best point-of-interest results that correspond to the Pinyin strings; and in response to presenting the list of N-best point-of-interest results as selectable points-of-interest via a user interface, receiving input via the user interface that selects a given point-of-interest from the presented list of N-best point-of-interest results.
