Beginning level Mandarin learners with different L1 backgrounds received six hours of Mandarin tone training using phrases and sentences produced by multiple native Mandarin speakers. Using Kay Elementric’s Sona Speech II software with real time display of pitch contours along with speech output on a PC computer, the trainees had both auditory and visual input when they recorded and compared their own productions with the training stimuli during the training. The trainees’ productions of Mandarin tones were judged by native Mandarin listeners to be significantly better at post test than at pretest. Such improvement was not matched by a control group that received the same classroom instruction but did not take the training. The trainees also reported very positive experience with the training. The findings suggest that the training is effective for learning Mandarin tones in a larger linguistic context beyond isolated syllables.
