Abstract

This paper presents results of research on isolated connected and continuous Farsi ‎number recognition over telephone. Effect of selecting basic recognition unit (phoneme or ‎word) is investigated and statistical neural and hybrid approaches are compared. In ‎Farsi digit and number recognition continuous density hidden markov models with ‎word and phoneme models embedded reestimation after baum-welch NN and hybrid ‎methods were used Experimental results show that in noisy and telephony conditions ‎the system employing cepstral vectors derived from Mel frequency filter-bank ‎analysis outperforms the system employing cepstral vectors derived from linear ‎prediction ana11sis. also it was observed that performance of HMM system is more ‎than that of both the NN and hybrid systems. The best performance of digit ‎recognition in isolated and connected Farsi digit recognition (with word models) over ‎Farsdigits1 telephony database was %99.1 and %83.7 respectively and the best ‎performance of word recognition in unconstrained Farsi number recognition (with ‎phoneme models) over Farsnumbersl telephony database was %91.1‎‏.‏
