Abstract:
1. A voice data transferring device which intermediates between a terminal device and a voice recognition server, in which the terminal device: records a voice of a user when the user is speaking; transmits the speech voice as a voice data; receives a recognition result of the transmitted voice data; and outputs the recognition result to the user, and in which the voice recognition server: receives the voice data from the terminal device; recognizes the voice data; and transmits the recognition result of the voice data, the voice data transferring device comprising: a storage unit that stores therein a first parameter value used for performing a data manipulation processing on the voice data and a voice data for evaluation used for evaluating voice recognition performance of the voice recognition server; a data processing unit that performs a data manipulation processing on the voice data for evaluation using the first parameter value, synthesizes a first voice data from the voice data for evaluation, performs a data manipulation processing on the voice data received from the terminal device using the first parameter value, and synthesizes a second voice data from the voice data received from the terminal device, a server communication unit that transmits the first voice data to the voice recognition server, receives a first recognition result from the voice recognition server, transmits the second voice data to the voice recognition server, and receives a second recognition result from the voice recognition server; a terminal communication unit that transmits the second recognition result of the second voice data to the terminal device; and a parameter change unit that updates the first parameter value stored in the storage unit, based on the received first recognition result of the first voice data.
