Sound control accelerator mistaken stepping prevention system

The invention relates to a sound control system for preventing an accelerator from being stepped on mistakenly. Data and instructions of a voiceprint recognition module, a scream recognition technology module and an accelerator angular acceleration detection module are exchanged through Bluetooth communication; wherein the voiceprint recognition module uses a Mel frequency cepstrum coefficient (MFCC) and vector quantization to generate a speaker identification code book to verify a driver identity; the squeal recognition technology module uses the mean value and variance statistics of each frame of voice signal as input vectors of a support vector machine (SVM), and uses a polynomial kernel function for training so as to recognize squeal sound with high accuracy; the accelerator angular acceleration detection module is used for monitoring possible accelerator stepping by mistake in real time; based on the comprehensive judgment of the modules, the execution module uses a push-pull type electromagnetic spring
