Embodiment Construction

[0035] In order to properly handle user interruptions and conduct friendly interactions, the accuracy of speech recognition must first be ensured as much as possible. The traditional speech system has poor tolerance for the special noise situation of speech echo, so better methods and technologies are necessary. When the recognition result is accurate and credible enough, the dialogue control center can be designed based on this to detect and manage user interruptions, and decide when and what to speak, so that the machine can communicate naturally with other people like a normal person . In order to solve the above problems, the present invention proposes a human-machine voice interaction method and system.

[0036] figure 1 It shows a schematic flowchart of the human-machine voice interaction method provided by an embodiment of the present invention, as shown in figure 1 As shown, the method includes the following steps:

[0037] 101. In the system state, the recording si...

Abstract

The invention discloses a man-machine voice interaction method. The method includes the following steps: dividing a recording signal and reference signal echo cancellation process into multiple sub-processes in a system state, splicing the sub-processes, and obtaining an output result of recording signal and reference signal echo cancellation, the reference signal being a voice signal emitted by a machine player; inputting the output result of recording signal and reference signal echo cancellation to a VAD model, and outputting a voice recognition result in real time when a user voice signal is detected; stopping a system from playing the voice signal when determining, based on the real-time output voice recognition result, the intention of a user and interrupting output of the system voice signal, entering a user state, and monitoring and recognizing the user voice signal; and sending feedback to the user according to the final voice recognition result when detecting that the output of the user voice signal is finished, and completing the interruption and responding process of one round of users. Interruption behaviors of users during an interaction process can be effectively detected, talking opportunities and contents of a machine can be decided, and thus the machine becomes smarter.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice interaction method and system. Background technique [0002] With the gradual development of voice core technology and application environment, voice interaction is being accepted and used by more and more users around the world. At present, the human-computer voice interaction process is alternately performed by "system speaking" and "user speaking". However, this voice technology does not support voice interaction perfectly, and there are certain limitations. The system does not allow the user to intervene (or interrupt) during the voice interaction with the user. The predictable result leads to poor flexibility and stability of the human-machine voice interaction system. [0003] Obviously, the above-mentioned human-computer voice interaction method is different from ordinary human-to-human communication, and normal people may interrupt each other when they...
