PORTABLE ACOUSTIC INTERFACE DEVICE, SYSTEM, AND METHOD FOR REMOTELY ACCESSING AUTOMATIC SPEECH/SPEAKER RECOGNITION SERVER |
摘要 |
<p>PROBLEM TO BE SOLVED: To permit an accurate speech recognition communication between a portable sound signal preprocessor(SSP) device and an automatic speech/ speaker recognition(ASSR) by converting feature vector data produced from digital signals into acoustic signals and communicating through a communication channel. SOLUTION: A ciphering device 130 ciphers data preprocessed by a digital signal processor(DSP) 120, and guarantees a safe exchange of the signals through a telephone line. A compression device 140 compresses the preprocessed data before transfer, and increases the data in the quantity forwarded and transmitted by audio signals when a band width of the line is narrow. And, the preprocessing of digitized data from a microphone 10 generates a sequence of a feature vector representing a speech pattern spoken to the microphone 100. Further, a receiver part of an acoustic coupler 150 converts audio signals from an ear pad of the receiver into digital signals to process them with DSP 120.</p> |
