resthandle.m

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 outputPv=restHandle(inputPv, useRest)
% restHandle: Rest handling for melody recognition
%	Usage: outputPv=restHandle(inputPv, useRest)
%		inputPv: input PV (pitch vector)
%		useRest: 0 ===> remove rests, 1 ===> replace a rest by its previous non-rest pitch

outputPv=inputPv;

% ====== Cut out leading/trailing rests
while outputPv(1)==0; outputPv(1)=[]; end
while outputPv(end)==0; outputPv(end)=[]; end

% ====== Handle in-between rests
if ~useRest
	outputPv(outputPv==0)=[];		%
