Development and Standardization of Speech Material in Rajasthani Language

Abstract

The purpose of the present study was to develop and to standardize the speech material (SRT & discrimination test material) in Rajasthani language. The methodology included collection of the polysyllabic and monosyllabic (CVC) words and familiarity, construction of lists of 'most familiar' polysyllabic and monosyllabic words and finally, standardizing the speech materials with the Rajasthani speaking adult subjects. Using thu procedure, two monosyllabic word lists and three polysyllabic word-lists were developed. There was agreement between the SRT levels and PTA of the subjects. The speech identification scores increased with the increase in presentation levels and reached maximum at around 40dBSL. Thus, these lists can be used reliably on Rajasthani speaking population in speech audiometry.
