Wavelet analysis is a newly developed theory , which overcomes the disadvantages of traditional fourier analysis . it has good localized features in both the time domain and the frequency domain and has important application value in the fields of signal processing , image processing , speech analysis and so on 小波分析是一門新興理論,它克服了傳統(tǒng)fourier分析的不足,在時(shí)域和頻域都具有良好的局部化特性,在信號(hào)處理、圖像處理、語(yǔ)音分析等領(lǐng)域有重要的應(yīng)用價(jià)值。
According to commonly steps of speech recognition , the key methods of speech recognition is discussed : a ) firstly , preprocessing and feature extraction in speech recognition is studied . we studied two important speech analysis methods and extracted two key features for speech recognition : mfcc and lpcc . on the base of the research we improve the algorithm and experiment with new method 論文根據(jù)語(yǔ)音識(shí)別的一般流程,主要針對(duì)語(yǔ)音識(shí)別系統(tǒng)的關(guān)鍵技術(shù)進(jìn)行探討: ( 1 )首先對(duì)語(yǔ)音信號(hào)的預(yù)處理和特征提取問(wèn)題進(jìn)行討論。分析了當(dāng)前最常用的兩種特征參數(shù), mfcc和lpcc ,在此基礎(chǔ)上對(duì)語(yǔ)音識(shí)別系統(tǒng)預(yù)處理和特征提取作了一些改進(jìn),并給出相應(yīng)的實(shí)驗(yàn)驗(yàn)證。
