Abstract
A method and system for providing immediate diagnostic feedback on speech samples of non-native speakers are disclosed. A scoring model is generated based on speech features extracted from one or more training speech samples. An evaluation speech sample is received and speech features of the evaluation speech sample are determined. Based on the scoring model and the speech features, diagnostic feedback is provided to the speaker. In an alternate embodiment, speech features are extracted from an evaluation speech sample. The speech features are then compared with optimal values, ranges of values, or norms for those features. Based on the result of the comparison, diagnostic feedback is provided to the speaker.
