Patent Document ID: 5562453
Application ID: 08016981

Base Claim:
1. A prompt-providing adaptive biofeedback speech tutor system for voice response to a programmed sequence of prompts and related responses by the user, characterized by: a) a user input transducer (2); b) an audible transducer (6); c) memory means (8, 9) including partition memory respectively for frequency domain and time domain information; d) a microchannel analyzer (7) connected to said user input transducer (2) for input so as to provide outputs to said memory means (8, 9); e) pattern comparator means (10) having memory means for frequency domain information of a user pattern against frequency domain information of a standard pattern and also of a time domain user pattern against a time domain standard pattern, to achieve a comparison score; f) means responsive to the comparison score in said pattern comparator means (10) to calculate overthreshold and underthreshold values and to provide respectively related overthreshold and underthreshold signals; f) biofeedback configuring means responsive to said overthreshold signal; and g) sequencing means responsive to said overthreshold signal and to said underthreshold signal to control the sequence of prompts.
