Twenty-nine consonants in the initial position and 31 final of CVC syllables were studied for perceptual confusions. The error matrices positions showed significant differences response. A quantitative procedure was adopted to ascertain which features most listeners, whether or not these similar positions. amount information transmitted bits per stimulus calculated all each feature separately. data indicated that rank order is two comparison with observations made by earlier workers a recent...

Pakistan has a high incidence of breast cancer in Asia, where annually 16,232 deaths are reported. There many exogenous and endogenous risk factors that affect the tumor suppressor genes oncogenes. The p53 gene is it role to protect whole genome from external internal stresses, which causes damages genome.The aim current study was investigate expression by using real-time PCR technique different grades as compared normal tissue.Fresh Modified Radical Mastectomy (MRM) samples (grade1-grade3)...

Perceptual confusions of 29 initial and 31 final consonants, embedded in nonsense CVC syllables, have been studied infinite peak clipping. It is found that the consonants (t∫, t∫h, dȝ, dȝh, k, kh, gh, s, ∫, j, r, l, w) are better recognized than (p, ph, b, bh, m, t, th, d, dh, n, .t, .th, .d, .dh, .r, .rh, ň, g, h). The effect clipping on intelligibility degradation features has observed both positions average graded as follows: (1) place, (2) nasality, (3) flapped liquids, (4) (5)...

Antibiotic-resistant bacteria have become the predominant etiology of endometritis and thus require effective treatment approaches. We used ultrasonography coupled with clinical signs presented complaints reproductive issues to investigate epidemiology, phylogenetic analysis, antimicrobial resistance, development novel therapeutics against Escherichia coli isolated from in bovine (n = 304 10 commercial dairy farms). The prevalence this study was 43.75%, while among these, 72.18% samples were...

The structure of perceptual confusions among 10 Hindi vowels /i, I, e, ɛ, a, ʌ, ɔ, o, U, u/ was studied in clipped speech. Front were recognized better than back vowels. It has been found most the cases that first and second probable incorrect have either openness vocal tract or place articulation common with corresponding correct vowel. This finding supports view can be perceived by these two distinctive features only. same (dimensions) used Wickelgren [J. Acoust. Soc. Amer. 38, 583–588...

AbstractAn experiment was done to study the effect of consonantal context on vowel perception in normal and infinitely clipped speech. In this experiment, 10 Hindi vowels | i, e, ∈, a, Λ, ɔ, o, U, u were placed hΛj—J |hΛw—w| contexts, recorded by two male speakers a tape. The recordings presented six well-trained listeners with or without infinite peak clipping. Listeners' responses summarized confusion matrix for each condition testing. Thus, four matrices formed. Study reveals that does...

This study presents some results of an experiment conducted to determine the effect on perception deleting different numbers 10-msec segments from initial and final parts VCV syllables. Eight stop consonants /p,t,t,k,b,d,d,g/ two affricates /ts,dz/ were combined with three pure vowels /i,a,u/ produce 30 stimulus words. An electronic gating apparatus was developed present sequential portions these The VC CV stimuli so obtained used for separate listening tests responses analyzed individual as...
