Voice interaction smart home system and voice interaction method

Abstract

The invention relates to the technical field of smart home, in particular to a smart home system capable of realizing the voice interaction function and a voice interaction method. The smart home system comprises a hardware terminal and a server terminal, wherein the hardware terminal consists of a gateway, a ZigBee router and ZigBee terminal nodes; a plurality of appliance equipment or sensors can be connected to the ZigBee terminal nodes; all the ZigBee terminal nodes have Mic voice input modules for acquiring voice analog information of users and converting the voice analog information to digital information; the digital information is transmitted to a ZigBee coordinator through the ZigBee router; the gateway consists of the ZigBee coordinator, a Wifi module, a voice processing module and a control command list module. Compared with the prior art, the smart home system has the following advantages: the operating rate of voice recognition can be prominently improved under the premise that the hardware cost is slightly incresed; the smart home system has the self-learning function, so that the default programming workload of various voice service environments at the early stage is saved; the accuracy of voice recognition is improved by adopting the spectral analysis method of a voice recognition module.

Description

[technical field] [0001] The invention relates to the field of smart home technology, in particular to a smart home system and a voice interaction method capable of realizing a voice interaction function. [Background technique] [0002] With the development of science and technology, voice interaction modules are more and more applied to smart home systems. Considering the applicability, convenience and miniaturization requirements of smart homes, the voice interaction systems currently used in smart homes basically use embedded systems, and most of these embedded systems use special voice recognition chips, such as MCU, DSP and voice The identification chip has certain limitations in its storage capacity and computing speed. Among the speech recognition modules currently on the market, the non-specific speech recognition module is basically used, but this module can only store 50 entries, the storage capacity is limited, and each entry is pre-input according to the applica...

Problems solved by technology

Considering the applicability, convenience and miniaturization requirements of smart homes, the voice interaction systems currently used in smart homes basically use embedded systems, and most of these embedded systems use special voice recognition chips, such as MCU, DSP and voice Recognition of dedicated chips, its storage capacity and computing speed have certain limitations

Among the speech recognition modules currently on the market, the non-specific speech recognition module is basically used, but this module can only store 50 entries, the storage capacity is limited, and each entry is pre-input according to the application scenario For example, the sentence "turn on the light in the bedroom" can be an entry. If the user says "turn on the light in the bedroom", the voice recognition module cannot recognize it.

In addition, this speech recognition module cannot recognize some modal particles such as um, ah

[0003] At the same time, the current smart home voice interaction systems in the industry can only implement simple voice command operations. These voice commands are also preset in the embedded system in the early stage. If the voice spoken by the user is not preset by the system, the system will Can't recognize
