Real time voice analysis and method for providing speech therapy

A computer-readable storage medium containing executable code for instructing a processor to analyze a speech signal produced by a learner, said processor being in communication with an audio input and a display, and said executable code instructing said processor to perform operations comprising:

• enabling receipt of said speech signal from said audio input;
• estimating a first formant and a second formant of said speech signal in real-time in conjunction with said receiving operation;
• presenting a target on said display characterizing an ideal pronunciation of said speech signal by incorporating said target into a two dimensional coordinate graph;
• and
• displaying a data element of a relationship between said first formant and said second formant by plotting said data element as an x-y pair of said first and said second formants in said two dimensional coordinate graph for comparison of said data element with said target to visualize an accuracy of said speech signal relative to said ideal pronunciation of said speech signal.

A method for providing speech therapy to a learner comprising:

• receiving a speech signal from said learner at an audio input of a computing system;
• estimating, at said computing system, a first formant and a second formant of said speech signal in real-time in conjunction with said receiving operation;
• presenting a plurality of targets incorporated into a chart on a display of said computing system, one each of said targets representing one each of a plurality of vowel sounds, and said one each of said targets characterizing an ideal pronunciation of said one each of said plurality of vowel sounds;
• displaying a data element of a relationship between said first formant and said second formant incorporated into said chart;
• and.
• comparing said data element with a selected one of said targets to visualize an accuracy of said speech signal relative to said ideal pronunciation of a selected one of said plurality of vowel sounds represented by said selected one of said targets.
