Problems solved by technology

When the correct rate of speech-to-text information is high, the accuracy of intent recognition is high; when the recognition rate of text information is low, a large amount of useful information is discarded by speech recognition during the recognition process, resulting in the user's intent of text information transmission also varies. lost

Embodiment Construction

[0031] Reference figure 1 The invention discloses an end-to-end speech intention recognition method, which includes the following steps:

[0032] S1. Input the voice to be recognized, perform noise reduction and feature extraction processing on it, and convert the voice to be recognized into a feature vector containing sound information;

[0033] S2. Input the feature vector into the speech intention recognition model, and output the speech intention.

[0034] In step S1, the noise reduction and feature extraction processing of the input speech includes a preprocessing process and a feature extraction process. The preprocessing process first cuts off the mute at the beginning and the end to reduce the interference caused to subsequent steps. The operation of mute cut is generally called Voice Activity Detection (Voice Activity Detection, VAD). Then the sound is divided into frames, that is, the sound is cut into small segments, and each small segment is called a frame, which is real...

Abstract

The invention discloses an end-to-end voice intention recognition method, and relates to the technical field of voice intention recognition. Most of existing voice intention recognition applications firstly acquire texts through voice recognition and then perform intention recognition, the accuracy of the intention recognition mode based on the texts seriously depends on the accuracy of translating the texts through voice recognition, and texts and pictures with inaccurate voice intention recognition exist. In order to solve the problem, the key points of the technical scheme are that the method comprises the steps: inputting a to-be-recognized voice, carrying out the noise reduction and feature extraction of the to-be-recognized voice, converting the to-be-recognized voice into a featurevector containing sound information, inputting the feature vector into a voice intention recognition model, and outputting a voice intention. The voice intention recognition model adopts a pre-training model thought of a deep learning network. According to the invention, the effects of reducing information loss caused by voice recognition and improving the voice intention recognition accuracy areachieved.

Description

Technical field [0001] The present invention relates to the technical field of speech intention recognition, and in particular to an end-to-end speech intention recognition method. Background technique [0002] With the rapid development of artificial intelligence technology in academia and its widespread use in life, voice interaction has become an important bridge for communication between humans and machines. The robot system needs to talk to the user and complete specific tasks. One of the core technologies is the determination of voice intent, that is, after the robot system receives the user's voice, it can determine the user's intent through the voice. [0003] Voice intent recognition technology refers to the recognition of the corresponding intent or feature of the input voice (the intent here includes single intent, multiple intent, slot value, emotion and other types of questions), and provides effective support for specific back-end service goals , High-performance voi...
