Problems solved by technology

[0005] In addition, some systems cannot support 2833 signaling in this way
[0006] Therefore, with the continuous development of the intelligent customer service system, the 2833 signaling method can no longer meet the actual needs under certain application conditions, and we need to explore other processing methods

Abstract

The invention relates to the technical field of speech technology, and discloses a method and a system for processing users' speech signals. The method includes the steps of, by a server, receiving users' speech signals which are mixture of external speech received by a speech terminal through a microphone and double-tone multi-frequency key tone of the speech terminal; subjecting the received users' speech signals to spectral analysis by the server; judging whether the preset key is pushed or not during talking according to double-tone multi-frequency target frequency component corresponding to the preset key in the frequency spectrum; if the key is pushed, then determining that current user speech input is over. By the method and the system for processing users' speech signals, whether speech is over or not can be determined accurately effectively.

Description

Technical field [0001] The present invention relates to the field of intelligent customer service voice, in particular to the technology of voice signal processing. Background technique [0002] With the continuous development of the intelligent customer service system, allowing customers to describe the problem to be consulted in one sentence and automatically dispatch orders based on the robot has become an important part of the system and an important way to improve user experience. Therefore, the automatic detection of the end point of the customer's voice becomes an integral part of the system. [0003] The traditional customer service system uses a combination of key operation input information and customer and manual customer service language interaction. Currently, RFC2833 signaling is commonly used. [0004] In this method, the # key in the key operation stage is used as the end sign of the key operation, and the client sends 2833 signaling to encode the customer voice and ...
