ABSTRACT
Objective To compile the basic disyllable vocabulary lists of the Hakka dialect speech in the Huizhou region,and basic materials for speech evaluation,according to requirement of speech audiometry and Hakka dialect phonology.Methods Based on the distribution of deaf patients and subareas of Hakka dialect in Guang dong Province,the Meihui dialect was selected as the major target.Meanwhile,several relevant pieces of literature,dictionaries and local chronicles were also studied as the reference in the process.Results A set of disyllable vocabulary,consisting of 5 lists,were compiled.Each list was made up of 40 words,and divided according to the principle of balance,high frequency and universality.The words in the lists were frequently used by local citizens(retelling rate＞91％).An analysis showed that there were strong correlations between each other.However,they were not equivalent,and could not be replaced by each other.Conclusion The compiled vocabulary lists are primarily verified to be suitable for Hakka citizen in the Huizhou region.Further adjustments,revision and research on their equivalence are also required.
ABSTRACT
Objective To compare the results of manually -tested speech recognition threshold (SRT ) with automatically software -recorded SRT in the trial of Mandarin disyllabic test ,exploring the significance to the clini-cal applying .Methods 128 normal people of different ages without hearing loss and 57 workers exposed to noise in an automobile manufacturing was selected .These two group of volunteers speak mainly Mandarin in their daily life . MADSEN Conera (Danmark) clinical audiometr was applied .A group of double syllable word list with the same dif-ficulty of equivalence was used as test material .The initial presentation level was 20 dB HL higher than PTA .Then compared the results of manually -tested SRT with automatically software -recorded SRT .Results In the normal group ,the automatic value SRT was 7 .84 ± 3 .98 dB HL ,the manual value was 9 .19 ± 4 .47 dB HL ,and the average value of speech frequency threshold was 7 .63 ± 5 .78 dB HL .In the noise group ,the automatic value SRT was 6 .10 ± 8 .40 dB HL ,the manual value was 18 .81 ± 9 .52 dB HL ,and the average value of language frequency threshold was 27 .18 ± 19 .13 dB HL .There was significant difference between the values of SRT tested manually and recorded automatically (P<0 .01) .Conclusion There are differences between SRT valued manually and automatically .The SRT in people with normal hearing can be tested using automatic -recorded method .This method is convenient for screening in people without hearing loss .To exam in people with hearing loss ,the manual test is more appropriate .
