Effects of low pass filtered input on adult non-lexical intonation in second language acquisition
by Harvey, T. Neal, M.A., California State University, Long Beach, 2016, 90; 10241066
Abstract (Summary)

This study examined the effect of a Low Pass Filter (LPF) on the accuracy of language learners producing intonation contours. Visualization technologies have proven useful in intonation instruction, and increasing pitch movement height and magnitude, while also spectrally limiting the speech stream may provide ways to raise the salience of intonation for learners as well. Nineteen participants were provided a pre and posttest between which they received either LPF training, Non-Filtered training, or no training. All input was given using the characteristics of Infant Directed Speech, providing, among other features, increased pitch movement height and magnitude. It was predicted that the LPF training would increase the accuracy of learners. The LPF did not significantly increase accuracy in intonation contour production, although focused training on intonation showed a significant increase in accuracy over no training at all.
