Abstract
Our technology can support a speech command and hand-free communication even in noisy environment such
as road noise without any stresses. Clear speech can be picked up from the noise-mixed sound in order to realize
speech command with high accuracy. A lot of computational complexy and memory was required to keep speech
quality and reduce only noise so far. This problem can be solved by using our acoustical knowhow, moreover, low
latency was able to be also achieved. In addition, a sign of howling was able to be detected rapidly by combining
multiple microphone array. Our goal is to improve an in-car acoustical environment by reducing noises which are
road noise, engiine noise, and any sound from other cars. We will also try to establish an event detection
technology in order to help a driving assistant or an early maintenance by detecting emergency car or anomalous
in sound.
