The recognition of sine-wave Mandarin Chinese in normal-hearing listeners
摘要
Abstract
Objective To study the mechanism in recognition of sine-wave Mandarin Chinese tones and sentences in normal-hearing listeners.Method The testing involved recognition of tones and sentences processed with sine-wave replica. A practice session was given to all 45 normal-hearing subjects before formal test. Feedback was provided to the subjects during the practice session (but not during the formal test) to familiarize the subjects with the sine-wave replica. In tone recognition, the subjects were forced to choose from four tone tokens displayed on the screen when he/she heard a sine-wave tone token. The aine-wave tone tokens were presented only once. The correct percent was recorded from each subject. The Mandarin hearing in noise test (MHINT) was adopted for the sentence recognition of sine-wave replica. The subjects could listen to the sine-wave replica as many times as he/she wanted. The correct percent was recorded.Results The mean score for tone recognition of sine-wave replica was 32.6% which was only slighdy higher than the chance level (25%). The scores ranged from 23.5% to 42.3%, with most scores ranging from 25% to 35%. In the tone recognition, tone 1 scored the highest (42.3% correct), followed by tone 3 (34.9% correct). Tone 2 and tone 4 scored 23.5% and 29.6% correct, respectively. The mean score for sentence recognition of sine-wave replica was 92.3%. The scores ranged from 78% to 100% correct, with most scores above 80% correct. Paired t test indicated that the difference between tone and sentence recognition of sine-wave replica was statistically significant (P<0.05). Conclusion The recognition of sine-wave Mandarin Chinese tones was poor but the recognition was nearly perfect for sentences. The top-down processes must play an important role in sine-wave Mandarin sentence recognition.关键词
