A field test of the SiVo aid with a profoundly hearing-impaired listener who has a left comer audiogram had been carried out in China. The testing materials were Chinese intelligibility test lists including syllable lists and word lists which are all phonetically balanced. The speech intelligibility tests were conducted under three different conditions:!, without the SiVo aid; 2. With the SiVo aid; 3. with the SiVo aid but no lip-reading. The testing results show that: L The SiVo aid is good for transmitting the pitch contours and for increasing the tone intelligibility of Chinese; 2. Lip-reading can contribute to lexical tone perception and the duration information of tonemes may be used by the listener; 3. Polysyllabic words gain higher intelligibility increment than monosyllabic words by using ISiVo aid. 4. Some interference between the SiVo aid channel and the lip-reading channel at word level was observed, and the training of continuous speech is' emphasized for Chinese.
