DTW (dynamic time warping) voice recognition-based truck examining method

The invention discloses a DTW (dynamic time warping) voice recognition-based truck examining method which comprises the step of examining the truck by a training template and a voice recognition template. The method comprises the steps of: taking a DTW voice recognition algorithm as the core; forming the recognition template by training the normal voice generated when a normal truck passes through a track and the voice generated when a damaged truck passes through the track; distinguishing the condition of the damaged parts of the truck during recognition; and transmitting a result to a control center, so that an early diagnosis and forecast process can be made, and the running security of the truck can be guaranteed. The DTW voice recognition-based truck examining method has the advantages of being high in fault detection and recognition rate, and simple in operation system.
