¿µ¹®³»¿ë¿ä¾à This document investigates objective measures for selecting a microphone for fartalking
speech recognition.
There are two major criteria to be considered, as follows:
i) the level of voice acceptance,
ii) the level of acceptance without distortion.
These testing criteria divide into the three kinds of measures as follows:
1) measure for speech attenuation,
2) measure for speech distortion and,
3) simultaneous measure for speech attenuation and distortion.
