Quantitative Methods for Analyzing Second Language Lexical Tone Production

The production of L2 lexical tone has proven difficult for learners tonal languages, leading to the testing different training techniques. To test validity these techniques, it is first necessary capture differences between L1 and datasets. current study explores three analyses designed compare tone: (1) using a single deviation score, (2) score calculations specific regions productions, (3) applying complexity-invariant distance measure two time series These were tested datasets sampled from previous effects visual feedback paradigm on Mandarin tone. Results suggest analyses, although useful providing an overall evaluation how speakers’ pretest versus posttest productions speakers, lose critical information about tone, namely pitch height, contour, timing production. third analysis, datasets, can provide pertinent lost in more robust manner.
