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 [pv, ti] = note2pv(note, pvTimeStep, pvTotalDuration, plotOpt)
%note2pv: note to pv conversion
%	Usage: [pv, ti] = note2pv(note, pvTimeStep, pvTotalDuration, plotOpt)
%		note: note vector of [pitch1, duration1, pitch2, duration2, ...], where the unit of duration is second
%		pvTimeStep: duration of each element in PV
%		pvTotalDuration: total duration of the returned PV (inf for the whole note vector)
%		pv: pitch vector
%		ti
