Smart home control system and method compatible with non-normal voice

Abstract

The invention discloses a smart home control system and method compatible with non-normal voice. The system includes a voice analysis module, an identification module, a decision fusion module, a matching module, an interactive feedback module, a control module and an online learning module. The voice analysis module extracts the acoustic features of voice. The identification module identifies voice using a corresponding identification model. The decision fusion module carries out decision fusion using a voting strategy based on weighted grading. The matching module matches the output result of decision fusion with preset modes. The interactive feedback module gives different voice interactive feedback according to the output result of the matching module. The control module controls the working state of smart home equipment. The online learning module saves voice to a server by means of online learning. The system and the method are simple and practical. Identification and decision fusion are carried out using a corresponding voice template, and the voice template is updated by means of online learning. The voice identification rate and adaptability of the system are improved.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a smart home control system and method compatible with abnormal voices. Background technique [0002] Language is the most important communication tool for human beings and the most natural way of interaction. As a way of human-computer interaction, the purpose of speech recognition is to enable machines to "understand" human language. After decades of research, speech recognition technology has been applied to the lives of ordinary people. With the continuous improvement of living standards, the concept of smart home has entered people's daily life, using advanced computers, embedded systems and network communication technologies to provide safe, comfortable and pleasant high-grade family life. Introducing voice recognition technology into smart home control, home appliances can also be controlled through voice commands instead of manual and remote control. [0003] However, in prac...

Problems solved by technology

[0003] However, in practical application scenarios, the accuracy of the speech recognition system is affected by many factors

In real life, the user's voice changes due to physical health reasons, and the abnormal voice caused by common colds changes the distribution of the speaker's personality characteristics, resulting in a mismatch between the cold voice and the speech recognition model obtained by using normal speech training, so that speech recognition The recognition accuracy of the system drops significantly
