Project DetailsIn this work we design a tool that is going to assist people with becoming more professional presenters. The tool will be based on an algorithm which will receive a presenter's audio recording as input, extract features out of it, and bestow the presenter with recommendations and advice to improve the quality of their presentation, based on the extracted features. Examples for those features are pitch, pace, sentences and breaks lengths, technical quality measure of the recording, etc. Those are parameters which will serve as reliable indicators to the quality of the presentation. Finally, we will design a user-friendly graphic interface which will include the feedback in verbal, numerical and graphic manners. In our solution the GUI shows the technical quality measure of the recording (based on Signal-to-Noise Ratio), and the pace as a function of time. Additionally, the algorithm tries to identify melody in the narration, and the GUI shows audio frames in which the speaker sounds stressed. Moreover, the GUI shows histograms of the lengths of the sentences and breaks of the speaker. Alongside each numeric or graphic result, an appropriate verbal message appears which either praises the presenter, or bestow them with a concrete way to improve.
