Robust voice command in high ambient noise level

A robust voice command recognition system for environments with high ambient noise levels was developed. The influence of noise is very important because the commands are usually used in situations like hand-free voice dialing in a car during operation, system-assisted production lines in a factory, and in airplane cockpits. The equipment which was developed is able to recognize commands in a high level ambient noise environment in which the noise level may be as high as 120 dB. Furthermore, this high recognition rate is guaranteed even for modified data, such as bone-conduction voice commands
