Abstract
A system for and method of providing feedback information relating to characteristics of the oral presentation to a speaker while giving a real-time oral presentation by analyzing representations of the audio signal corresponding to the oral presentation. The feedback information can then be provided to the speaker during the real-time presentation to assist the speaker and improve the oral presentation.
Claims26
A system comprising:
- signal processor for processing an audio signal corresponding to and during a real-time oral presentation to generate at least one representation of the audio signal including at least an energy function representation and a zero-crossing rate function representation;
- analyzer for analyzing at least the one representation to generate at least one characterizing indicator corresponding to the oral presentation;
- output device for providing feedback information characterizing the oral presentation in response to the at least one characterizing indicator.
A method comprising:
- processing an audio signal corresponding to and during a real-time oral presentation so as to generate at least one representation of the audio signal including at least an energy function representation and a zero-crossing rate function representation;
- analyzing at least the one representation to obtain at least one characterizing indicator corresponding to the oral presentation;
- determining feedback information from the at least one characterization indicator;
- providing the feedback information characterizing the real-time oral presentation.
A computer readable medium for causing a processor in a computer system to perform processing instructions comprising:
- processing an audio signal corresponding to and during a real-time oral presentation so as to generate at least one representation of the audio signal including at least an energy function representation and a zero-crossing rate function representation;
- analyzing at least the one representation to obtain at least one characterizing indicator corresponding to the oral presentation;
- determining feedback information from the at least one characterization indicator;
- providing the feedback information characterizing the real-time oral presentation.
