| This article takes SPCE061 A single-chip microcomputer as the core processor and uses its characteristics suitable for digital voice recognition to design a voice question answering interactive system in a specific medical field.This article takes the common diseases and medications of cardiovascular medicine as the research theme,and combines the knowledge base and answer knowledge base of common diseases and medications to provide users with a question-and-answer interactive hardware platform.The realization of the function of the voice question answering interactive system is mainly divided into the establishment of a knowledge base,voice training and recognition,and the extraction of correct answers.The establishment of the knowledge base uses the web crawler technology to obtain common diseases and medication information to build an offline knowledge base,and As the support of the underlying data of the system;the training and recognition part of the voice trains and recognizes frequently asked questions by calling the single chip API function,and sets up the corresponding question and answer statements to establish the frequently asked question and answer library;Perform question analysis,information retrieval,answer extraction and other operations on it,and use the rules and syntax analysis methods,vector space model-based TF-IDF algorithm,and window model-based answer extraction algorithm to match the identified questions with confidence The highest answer is finally fed back to the user in the form of voice broadcast.This paper tests the function of the system through a large number of application experiments,and evaluates the performance of the system with the question recognition rate and answer matching rate.After data analysis and statistics,the system’s question recognition rate and answer matching rate reached 86.3% and 84.9%,respectively.This shows that this article finally realized the question-answer interactive function of the system "seeking medical advice and medicine". |
