Problems solved by technology

[0008] However, due to the ever-changing traffic sounds, different types of sounds have very similar characteristics; and the same category of sounds will also have large differences, such as horn sounds, different models of horns, or the same horn installed on different vehicles, the other Acoustic characteristics are also very different, so it is very difficult to accurately identify these typical traffic sounds
When the unified characteristics of each type of sound cannot be determined, the theoretical mathematical model of sound recognition is also difficult to establish

Abstract

The invention provides a method and a system for voice recognition. The method includes acquiring a sound in real time, the sound including traffic noise; Converting the sound into a discrete digitalsignal and a feature quantity; Real-time optimizing a depth learning neural network model according to the discrete digital signal and the feature quantity. The sound is recognized using a depth learning neural network model. The voice recognition method and system of the present invention can accurately recognize the voice type appearing in the road and automatically improve the recognition accuracy in the recognition process.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to a voice recognition method and system. Background technique [0002] In road traffic, there will be many different sounds. With the rapid development of intelligent transportation technology, it is particularly important to identify different types of sounds in a timely and accurate manner. For example: [0003] (1) The recognition of the honking sound of motor vehicles and the engine roar of illegally modified sports cars is conducive to correcting illegal acts and creating a quiet and civilized urban traffic environment. [0004] (2) The identification of special vehicles with sirens is beneficial to realize the intelligent traffic control. [0005] (3) The identification of the driving noise of trucks, passenger cars, buses and motorcycles is beneficial to the study of traffic noise distribution. [0006] (4) The identification of emergency braking sound ...
