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 invention discloses a voice interaction method and device, and the method comprises the steps: obtaining voice input information when a voice input function is detected to be awakened; performing separation operation on the voice input information according to pre-stored first noise frequency spectrum information to generate human voice frequency spectrum information and second noise frequency spectrum information; determining a first volume amplitude according to the second noise spectrum information, and determining a human voice average amplitude according to the humanvoice spectrum information; and providing matched voice reminding information according to the amplitude relationship between the first volume amplitude and the average human voice amplitude. According to the technical scheme provided by the embodiment of the invention, voice information input by a user is separated and human voice frequency spectrum information is generated through acquired noise information of surrounding environment, so that the volume guidance of the voice input by the user is realized, it is ensured that the speaking voice of the user meets the recognition requirement ofa voice input function, and the voice recognition accuracy is improved.

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...
