自动语音识别源码对非特定人的孤立词语音识别算法 进行研究。考虑到语音识别技术在嵌入式系统处理能力较弱、存储空间有限的问 题上进行算法的选择和优化

function songData=songDbRead(dbName, encoded)
%songDbRead: Read .txt and .db file into a songData structure
%	Usage: songData=songDbRead(dbName, encoded)
%		txtFile: index file name.
%		dbFile: binary database file name.
%		encoded: 1 if dbFile is xor-encoded
%		songData: a structure contains fields specified in .txt file
%			In particular, songData(i).track is a vector containing (pitch, duration) pairs read from dbFile.
%			pitch is in semitone, duration is in 1/64 seconds
%
%		For example:
%			songDb=songDbRead('childSong', 0);
%			dispStructInHtml(songDb);
