US Patent 9947322 Systems and methods for automated evaluation of human speech

Systems and methods for evaluating human speech. Implementations may include: a microphone coupled with a computing device comprising a microprocessor, a memory, and a display operatively coupled together. The microphone may be configured to receive an audible unconstrained speech utterance from a user whose proficiency in a language is being tested and provide a corresponding audio signal to the computing device. The microprocessor and memory may receive the audio signal and process the audio signal by recognizing a plurality of phones and a plurality of pauses and calculate a plurality of suprasegmental parameters using the plurality of pauses and the plurality of phones. The microprocessor and memory may use the plurality of suprasegmental parameters to calculate a language proficiency rating for the user and display the language proficiency rating of the user on the display associated with the computing device.
