Abstract

The invention relates to a voice recognition method and system for correcting a noise text, and a storage medium, and the method comprises the steps: obtaining an audio signal; performing voice recognition on the acquired audio signal to obtain an initial recognition text; performing word segmentation operation on the initial recognition text to obtain decomposed phrases; recombining the decomposed phrases to obtain a plurality of recombined statements; calculating a probability value of each recombined statement by utilizing an N-Gram model; calculating a weight value of each recombined statement by utilizing a TF-IDF model according to a pre-constructed service dialogue corpus; and calculating a weighted probability value of each recombined statement according to the probability value and the weight value of each recombined statement, and selecting the recombined statement of which the weighted probability value meets a preset condition as a result recognition text. According to theinvention, the noise text mingled with the voice of other people can be filtered to obtain the voice recognition result conforming to the current dialogue scene, the voice recognition accuracy is improved, and the interaction efficiency and experience are improved.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a speech recognition method, system and storage medium for correcting noise text. Background technique [0002] With the continuous development of artificial intelligence technology, artificial intelligence technology is used in more and more scenarios to interact with users and provide various services. Among them, speech recognition plays an important role in human-computer interaction because it is more suitable for people's normal communication habits. [0003] Scenes such as bank halls or business halls are relatively noisy environments. During the dialogue between the intelligent robot and the user, the intelligent robot will not only acquire the user's voice, but also pick up a lot of environmental noise. These ambient noises could be other people's conversations, or machines, or the sounds of the street outside. Due to the interference of these environmental...
