Edit and evaluation of Mandarin sentence materials for Chinese speech audiometry

TLDR: The sentence lists for mandarin speech test materials should also get used for hearing impaired subjects, hearing aid users and cochlear implant recipients in different stages of the intervention and rehabilitation.

Abstract: Objective To edit the sentence list for mandarin speech test materials （MSTM） and to test their equivalence in order to use the list as routine clinical speech tests for evaluation of cochlear implants and hearing aids in different stages of the intervention and rehabilitation. Methods Firstly, two groups of professionals were set up ： one for establishing the principles of the edit, another for experiments. The criteria to guide the selection of spoken sentences were as following：①suitable for everyday speech audiometry, esp. clinically usage;② a normal sampling of everyday spoken sentences in mandarin. Totally, 300 sentences were selected in 30 lists for the experiment. The record cassette was used by a male speaker. The college students （54 persons, 54 ears） with normal hearing participated in the equivalence test. Two statistic methods were used for equivalence analysis. Results Through speech tests and statistic analysis, 2 sets with 29 lists （290 sentences） were selected as our equivalent lists for further evaluation and clinical trial. Conclusions By setting up the strict criteria of selecting sentences, speech test method and statistic analysis, 2 sets of 29 lists （290） sentences were chosen as our speech evaluation materials, but it was necessary for further analysis in different laboratories and clinics. The sentence lists should also get used for hearing impaired subjects, hearing aid users and cochlear implant recipients. Key words: Speech audiometry; Chinese; Mandarin; Equivalence
