基于MatlabGUI语音识别推箱子的设计

摘要

Based on the brief introduction of the core algorithm of the game, the paper presents a new method for the design and implementation of a real time speech recognition based on Matlab GUI. The purpose is to realize the communication between the computer and the computer in more ways.The main problem of the problem of speech input, filtering, feature extraction, signal and template matching, etc. Speech input and endpoint detection rely on energy and zero crossing rate detection, can make use of data is real voice signal data, thereby reducing the amount of data and computing and reduce processing time. After the MFCC feature extraction of speech signal, and then DTW algorithm and the database template comparison, can maximize the efficiency of recognition.%Matlab，是国际上使用最为广泛的科学与工程计算软件工具。其具有强大、丰富的内置函数和工具箱。在简要介绍推箱子游戏核心算法的基础上，给出一种基于Matlab GUI的能进行实时语音识别的推箱子游戏设计与实现方法，目的是用更多的方式实现与计算机的交流，属语音信号处理的范畴。主要解决的问题有语音的录入、滤波、特征值提取、信号与模版的匹配等。语音录入和端点检测依赖于能量和过零率的检测，可使采用的数据真正是语音信号数据，从而减少数据量和运算量并减少处理时间。后将语音信号的MFCC特征参数提取，再用DTW算法与数据库中模版对比，可最大化提高识别效率。本文能成功识别语音输入信号，并在游戏中实时反馈。在非特定人声识别时，需建立的语音数据库足够大，才能有很高的识别率。基于本文，语音识别可与现实生活中更多的事物相结合，不局限于游戏。
