Improved Chinese String Matching Algorithm in Smart Home

In recent years, with the fiery development of the smart home industry, the development of smart home applications has become increasingly important. With the smart home application of intelligent software requirements, this paper aims to solve the problem of Chinese string matching accuracy encountered when developing client voice control functions. In the smart home scenario, the voice control instruction string often has a three-stage structure of the verb + key + home nouns. After comparing and analyzing the previous Chinese string matching algorithms, this paper uses the forward maximum matching algorithm to divide the word segmentation, and improve the editing distance algorithm combined with the Chinese character phonetic code and the Chinese character configuration. Finally, a Chinese string matching algorithm is proposed which is suitable for smart home voice control scenarios. The experimental results show that this algorithm is effective, feasible.
