Pronunciation measurement device and method

A method of measuring pronunciation, comprising:

• receiving voice input;
• performing a look-up operation to obtain a predetermined model for the voice input;
• applying the voice input to the model to provide a score, including providing a first output providing measurements of durations of sub-words and a second output providing measurements of correlations between sub-words in the voice input and sub-words in the predetermined model;
• analyzing the score with respect to a score for a predetermined speaker, thereby providing a result wherein the step of analyzing the score comprises performing statistical analysis of the first output with respect to predetermined measurements of durations of sub-words for the predetermined speaker;
• and
• indicating the result, including indicating a confidence measure for durations of sub-words in the voice input.

A device for pronunciation measurement comprising:

• a speech modeling element having an input to receive a signal representing a voice of a speaker and an output;
• a speaker database;
• an analysis element having a first input coupled to the speaker database and a second input coupled to the output of the speech modeling element and having an output;
• and
• a graphic user interface indicator device coupled to the output of the analysis element, including an indicator of confidence measure for a duration of a phoneme of the voice of the speaker and an indicator of a confidence measure for quality of a phoneme of the voice of the speaker.
