Problems solved by technology

[0003] The current speech recognition function, due to the diversity of use scenarios, such as at home, in a car or in a shopping mall, etc., the recognition effect will inevitably be affected by environmental noise during the recognition process, but users do not know how the current noise environment affects the recognition effect How much impact will it cause, often after the user sends out a voice command, after the voice recognition process, and obtains the voice processing result, it is found that there are a lot of errors in the voice recognition, and the voice command needs to be re-entered, resulting in the recognition efficiency of the voice recognition function. low accuracy

Abstract

The embodiment of the present invention discloses a voice interaction method and device. The method includes: acquiring voice input information when it is detected that the voice input function is awakened; and separating the voice input information according to the pre-stored first noise spectrum information Operation, generating vocal spectrum information and second noise spectrum information; determining the first volume amplitude according to the second noise spectrum information, and determining the average vocal amplitude according to the vocal spectrum information; according to the first volume The amplitude relationship between the amplitude and the average amplitude of the human voice provides matching voice reminder information. According to the technical solution of the embodiment of the present invention, through the obtained noise information of the surrounding environment, the voice information input by the user is separated, and the spectrum information of the human voice is generated, so as to realize the volume guidance of the voice input by the user and ensure that the voice of the user conforms to the The recognition requirements of the voice input function have improved the accuracy of voice recognition.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent recognition, and in particular to a voice interaction method and device. Background technique [0002] With the continuous advancement of software technology, various applications (Application, APP for short) appear in people's field of vision, speech recognition function as an invisible link between users and applications, has become a extremely important component. [0003] The current speech recognition function, due to the diversity of use scenarios, such as at home, in a car or in a shopping mall, etc., the recognition effect will inevitably be affected by environmental noise during the recognition process, but users do not know how the current noise environment affects the recognition effect How much impact will it cause, often after the user sends out a voice command, after the voice recognition process, and obtains the voice processing result, it is found tha...
