Abstract

The invention discloses a robot speech recognition method based on natural language processing. The method comprises the following steps: acquisition of speech signals, pretreatment of the speech signals, feature extraction, model training and pattern matching. By carrying out a series of processing on the natural language, a robot is allowed to carry out speech recognition on the natural language, thereby improving recognition accuracy and efficiency; through processing measures of filtering and the like, cleaning degree of the speech signal is improved, thereby facilitating recognition; and through the speech recognition method, intelligence level of the robot is improved.

Description

technical field [0001] The invention belongs to the technical field of speech recognition, in particular to a method for robot speech recognition based on natural language processing. Background technique [0002] With the development of science and technology, speech recognition technology is gradually forming a relatively complete theoretical system, and its application products have also been launched one after another. Robots with the ability to recognize self-identified speech are one of them. Adding natural language and speech recognition technology to the robot communication system can completely change the traditional robot communication service form. Using a communication network with voice processing and voice technology capabilities, the robot can easily query and extract relevant information from the remote database system. Natural language processing technology and speech recognition technology are gradually becoming the key technology of human-machine interfac...
