[Development and equivalence evaluation of monosyllable lists of mandarin speech test materials]

To find a good speech material in audiology routine tests and cochlear implant evaluation, the monosyllable lists which were a part of mandarin speech test materials (MSTM) were edited and recorded. The equivalence test was done for all the lists.

The professional group was set up at first, which composed of specialists of Chinese, mandarin teaching, linguistics and statistics. The principles of word selection were established according to the coherence with international speech test materials and mandarin. Ten Monosyllable lists, each of which has 50 mandarin words according to phonemic balance and criteria of speech audiometry, were edited. The balance was 3-dimension: vowels, consonants and four Chinese tones. One cassette was recorded by a male speaker (radiobroadcaster). The 72 normal hearing subjects were tested monaurally with ten monosyllable lists and the materials were presented by the earphone. The equivalence evaluation was done at the level of about 50% correct scores.

Statistic analysis shows that 7 lists were equivalent in difficulty. They were ready for future research and clinical trial.

The mandarin monosyllable lists were edited in terms of international standard and Chinese 3-dimension phonemic balance. Seven of them met the demands for research and clinical application.
