Development and standardisation of the sentence identification test in the Kannada language

Abstract

Background: The present study aimed to develop and standardise the sentence identification test in the Kannada language. This study used a normative research design that included development and standardisation of sentence tests. Material and methods:A total of 700 sentences in the Kannada language, selected from various sources, were evaluated for naturalness, predictability, and equivalency by 33 participants. Sentences considered to be natural, low in predictability, and equivalent were used to construct 30 lists of 10 sentences each. Standardisation of the material and list equivalency were assessed on 100 listeners with normal hearing ability.Results: Based on ratings of naturalness and predictability, 564 sentences were considered as highly natural and of low predictability. Of these, 316 were found to have equal difficulty based on a performance-SNR function and were used to construct 30 lists. Repeated measures ANOVA and Bonferroni post hoc tests revealed Lists 1, 3, 15, 16, and 30 to be significantly different from at least one of the other lists. After removing these lists, the mean identification score for the final 25 lists at -5 dB SNR was 54%. Conclusions:The sentence identification test in Kannada for adults consists of 25 homogenous lists. The normative for the same is also given in the study. Its application is being assessed for hearing evaluation in the clinical population.

Validation and cross‐linguistic adaptation of the Frenchay Dysarthria Assessment (FDA‐2) speech intelligibility tests: Hebrew version

“…Second, predictable sentences, those which had keywords that could be easily guessed, were excluded. This was important since highly predictable sentences may improve intelligibility scores relative to sentences with low predictability (Geetha et al., 2014). Indeed, for speakers with dysarthria, high semantic predictiveness improved sentence intelligibility (Garcia & Dagenais, 1998).…”

“…Sentence's order was randomized for each participant. Predictability ratings were used to exclude highly predictable sentences because these may elevate intelligibility scores compared with sentences with low predictability (Geetha et al., 2014).…”

“…The final word of each sentence was deleted and replaced by a fill‐in blank space. Participants were asked to write the word that, in their opinion, best fits the blank space (for a similar procedure, see Geetha et al., 2014). Sentence's order was randomized for each participant.…”

“…The standard Kannada sentence lists, developed by Geetha et al, 12 were used for the study. Each list consisted of 10 sentences, and each sentence consisted of 4 keywords so that a maximum score of 40 could be achieved.…”

“…Lists from the Kannada sentence bank 12 were used in this part of the study too. The sentences were recorded in an acoustically treated recording room by an adult female and male speaker who were native speakers of Kannada.…”
