Automatic speech recognition measures havebeen investigated as scores of segmental pronunciationquality. In an experiment, contextindependenthidden Markov phone models weretrained on native English and Swedish readchild speech respectively. Among various studiedscores, a likelihood ratio between thescores of forced alignment using English phonememodels and the score of English or Swedishphoneme recognition had the highest correlationsto human judgments. The best measureshave the power of evaluating the coarse proficiencylevel of a child but need to be improvedfor detailed diagnostics of individual utterancesand phonemes.
