发明名称 METHOD FOR PROVIDING VISUAL FEEDBACK FOR VOWEL QUALITY
摘要 A method for obtaining visual feedback for vowel quality is disclosed. By filtering and decomposing audio signals in formants, one or more software modules and/or applications may determine the type of phoneme in an audio signal that corresponds to a vowel. First and second formants may be measured in their frequencies; subsequently frequencies values of first formant and second formant may be assigned as X and Y coordinates, respectively. These (X, Y) coordinates may be used for graphing points and trajectories of the points in a Cartesian coordinate system while the user is pronouncing a vowel. Thus, graphic feedback for vowel pronunciation may be obtained.
