SPEECH ESTIMATION SYSTEM, SPEECH ESTIMATION METHOD, AND SPEECH ESTIMATION PROGRAM

摘要

A speech estimation system includes: a transmission unit (2) which transmits a test signal; a reception unit (3) which receives the test signal; and a speech estimation unit (4) which estimates a speech from the received signal. The transmission unit (2) transmits a test signal toward a speech organ. The reception unit (3) receives the test signal reflected by the speech organ. The speech estimation unit (4) estimates a speech or a speech waveform according to the waveform of the reflected wave of the test signal received by the reception unit (3).
