Voice command recognition method and vehicle voice command recognition device

摘要

The present invention provides a voice command recognition apparatus in consideration of the noise of a vehicle so that a situation in which the voice command cannot be recognized according to the state of the noise does not occur even when the noise changes during driving of the vehicle. The purpose is to increase the.;The present invention is a means for realizing this object, in a method for recognizing a voice command of a vehicle comprising a voice input step, a preprocessing step, a feature vector extraction step, and a voice pattern classification step, the current speed of the vehicle and the current engine. The driving noise estimation step, which is a step of estimating the current driving noise based on the RPM value, and based on the result estimated by the driving noise estimation step, is performed. The present invention provides a method for recognizing a voice command of a vehicle and a method for recognizing a voice command using the method, comprising: selecting a codebook designed for a noise state and selecting a codebook for classifying voice patterns.
