Acoustic Analysis: openSMILE ™

A part of the features analyzed for the acoustic analysis were pauses, rhythm and articulation. Speaking is not only unconsciously shaped on the basis of these characteristics, but can also be consciously designed. The way of speaking is an important part of delivering information and leading an audience through it in the context of a speech.
