DEVICE FOR PROVIDING VOICE PROCESSING SERVICE, AND MICROPHONE

摘要

PROBLEM TO BE SOLVED: To provide a system surely eliminating illegal use without forcing a user of pronunciation evaluation service to take complex authentication procedures.

SOLUTION: A student's terminal 10 uses a microphone array 30 to receive a service. A sound collecting property control part 37 of the microphone array 30 controls a sound collecting characteristic on the basis of a sound collecting characteristic control parameter stored in a parameter storage memory 36. A DSP server device 40 produces the sound collecting characteristic control parameter of each student, and registers the produced sound collecting characteristic control parameter as an authentication key.
