Automated Objective Speech Intelligibility Assessment System
Agency / Branch:
DOD / CBD
Based on our successful experiences in automatic speech recognition, we propose a unique and promising solution for the automated objective speech intelligibility assessment system. It consists of a pair of head and torso simulators placed at the same distance as typical face-to-face communication, a power amplifier, a laptop computer, a speech recognizer, and console software. The simulator has acoustic properties similar to those of a human and can wear any kinds of masks that need to be tested. During the test, pre-recorded speech is played from the loudspeaker installed in one simulator's mouth and picked up by the microphone in another's ear. Recorded speech signals are then sent to an automatic speech recognizer in a laptop. The speech intelligibility is represented as a score associated with the speech recognition accuracy. Special techniques are proposed to address the challenges in robust speech recognition and to ensure the success of this project.
