汉语单音节和双音节词感知清晰度的测算方法研究

o assess the equivalence of clinical speech audiometric materials, we need to calculate the perceptual articulation of usual language units (monosyllable, disyllabic word, short sentences, etc). This paper investigates the independent contribution of initial and final based on ZHANG's conditional probability model, emphasizing the effect to the perceptual articulation of monosyllable, disyllabic word, which is resulting from the factors of tone, junctures and word frequency. We organized a monosyllable and a disyllabic word audiometric tests to get data base just as the phonematic perceptual confusion matrix and the measured value of articulation in some transfer conditions (all-pass, LP1600, HP1600, etc). These test help to determine the frequency coefficient of the perceptual definition model. Compared with the existing independent probability model and conditional probability model, the new perceptual model has a lesser deviation degree and a better correlation with the measured value.
