Method for improving voice recognition rate of automobile voice control system

Abstract

The invention discloses a method for improving the voice recognition rate of an automobile voice control system. The method comprises the following steps of: (1) configuring a voice prompt module for the automobile voice control system to output a voice prompt signal to perform time-sharing control on entertainment signals played by an automobile sound system; (2) configuring a process of voice instruction classification method using classifying input and classifying recognition for the voice recognition module of the automobile voice control system; and (3) configuring a process using classified voice instruction robustness recognition method for the voice recognition module of the automobile voice control system. The method provided by the invention can effectively improve the voice difference factors influencing the recognition rate of the automobile voice recognition system, thereby keeping the expected accurate recognition rate and improving the voice recognition reliability and stability of the automobile voice recognition system. The method can be also applied to electrical appliance voice control systems of automobiles of different grades.

Description

technical field [0001] The invention belongs to the technical field of automobile electrical control, relates to a speech recognition system for automobile voice control, in particular to a method for improving the speech recognition rate of the automobile voice control system, which is used for the speech recognition of the automobile voice control system. Background technique [0002] At this stage, the methods used to improve the recognition rate of speech recognition systems often focus on algorithms or hardware devices. With the rapid expansion of the auto market and the continuous expansion of the car consumer group, the structure of the car consumer group has undergone tremendous changes, from bustling cities to vast countryside, from ECO white-collar workers to civilian workers, from high education to low compulsory education Education, this consumer group has the same desire for the pursuit of car performance. However, the pronunciation is not very standard among ...

Problems solved by technology

Although this control method has a strong ability to suppress the noise in the car driving environment, it has the following deficiencies: (1) There is an impact of the driver's voice on the recognition rate of the car speech recognition system

(2) The voices of multiple occupants other than the driver cannot be recognized

(3) Selecting the word whose pronunciation is most similar to the driver's voice from the phonetic vocabulary does not substantially improve the reliability of identifying the driver's speaking intention

Among them, there are many problems in the identification and determination of the keywords of voice commands. Taking the air conditioner as an example of voice-activated electrical appliances, the two basic keywords are "turn on the air conditioner" and "turn off the air conditioner". words are the same, which will greatly reduce the reliability of system recognition, and even cause misoperation.
