Intelligent household system based on speech recognition

Abstract

The invention relates to an intelligent household system based on speech recognition. The system is characterized in that: the system comprises: a plurality of speech acquisition units possessing wireless data transmission functions and a host; the host comprises: a microprocessor, a speech pretreatment module which connected with the microprocessor, a 485 communication module and a storage module; the 485 communication module is connected with a household appliance entrance guard controller; the speech acquisition units transmits collected speech data to the speech pretreatment module through a wireless communication mode so as to carry out amplification, denoising and framing processing; then, a processed speech signal is compared with the speech model data stored in the storage module; the microprocessor controls the household appliance entrance guard controller through the 485 communication module according to a comparative value. The system of the invention can perform speech intelligence control to the entrance guard and the household appliance through the speech recognition. A user does not need to run to a switch position of the corresponding household appliance or the entrance guard to carry out controlling. The user can remotely control the household appliance through a telephone or a mobile phone. A user experience of the intelligent household can be increased.

Description

technical field [0001] The invention relates to a voice recognition-based smart home control technology in a smart home. Background technique [0002] With the continuous warming of the global information age, people have put forward intelligent and humanized requirements for the houses that have been living for thousands of years. Using current information technology, the continuous development of smart homes has provided people with a lot of intelligent services . [0003] Smart home has gone through the initial stage of nearly 6 years in China, and the development speed is slow. This is mainly because a lot of funds have not been invested, and the development technology is not mature in the short term. However, with the continuous provision of scientific and technological level, the products have been gradually promoted in the market, mainly focusing on the research of some scattered intelligent building intercom subsystems, such as three-meter copy and copy system, acce...

Problems solved by technology

[0005] 1. Traditional switch control: This kind of switch is the most important in the market now. There are traditional mechanical switches, semi-intelligent sensor switches and time-delayed two-state switches. This kind of switch is generally embedded in the wall. A position or a fixed button on the home appliance, when we need to control, we need to go to the position of the switch or the home appliance to operate, which is very inconvenient

[0006] 2. Remote control: Now the infrared technology is quite mature, and many home appliance manufacturers have launched their own infrared remote control, such as TV, air conditioner, etc. The disadvantage of this kind of remote control is that the remote control needs to face the home appliance to control and the distance should not be too far away. Far, and many remote controls are inconvenient to operate and store

[0007] It is precisely because of these limitations of the existing smart home system that it is difficult to meet people's human needs. More people of insight are looking forward to new technologies to solve these problems, and voice recognition technology is just a very good way to solve these problems. good plan
