Problems solved by technology

However, with the above method, since the user is required to speak a speech signal that conforms to specific grammatical rules, the user is restricted in expressing control instructions and cannot express freely. Instructions, due to a certain error rate in the speech recognition process, the resulting text is not guaranteed to still conform to specific grammatical rules. Therefore, the designed system lacks flexibility and stability, and the user experience is poor

Embodiment Construction

[0045] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the inventive concept. These all belong to the protection scope of the present invention.

[0046] Various embodiments of the present invention are directed to the method for identifying user control intentions in the prior art of intelligent voice control. The user control intentions are extracted from text information according to established grammatical rules through phonemes, syntax trees or fixed sentence formats, and then converted into corresponding user control intentions. The user's control intention expression is limited, and the error of the speech recognition process will also lead to the p...

Abstract

The invention provides an intelligent voice control oriented intent recognition method and device. The method comprises the following steps: acquiring text information input by a user; performing character segmentation processing on the text information so as to obtain a first character sequence of the text information; inputting the first character sequence into an intent recognition model to generate a second character sequence, wherein the intent recognition model comprises an encoder-decoder model combining with an attention mechanism; and merging the second character sequence, and formingan instruction sequence to determine the user intent. According to the method and device disclosed by the invention, the attention mechanism and the encoder-decoder model in in-depth learning are innovatively applied onto user intent recognition, the novel intent recognition method and device are realized, and the flexibility and fault tolerance of the intent recognition are improved.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, and in particular, to an intention recognition method and device for intelligent voice control. Background technique [0002] With the rapid development of speech recognition, natural language processing and deep learning, intelligent voice control technology has gradually been applied to various fields of people's lives, such as the field of smart homes, the field of voice-controlled intelligent robots, and smart speakers. The intelligent voice control system generally includes core technologies such as voice recognition, natural language processing, and hardware underlying intelligent control. [0003] In the intelligent voice control system, the natural language processing process mainly recognizes the user's control intention on the control object into a series of instructions that the control object can execute. However, the language itself is full of diversity a...
