Acoustic analysis: What can the physical properties of the speech signal tell us about a person’s spoken communication? Are certain acoustic parameters deviant compared to otherwise healthy speakers? Can these acoustic differences help to explain the differences noticed by the speaker or by listeners?.Different aspects of spoken communication can be measured in multiple ways. That is, atypical speech production that arises due to abnormalities in the brain (for example, changes in the brain associated with Parkinson’s disease). In my research, I work with people who have neurological speech disorders. Come along for the joy of learning where the heck the backspace key lives in Praat, and other fun discoveries. Future posts in this series will introduce a script that allows for a listener to transcribe speech in Praat, rather than (or in addition to) rating it along a VAS.An upcoming post will provide a step-by-step of how it was written in Praat (in large part as a reminder to future me, in the inevitable case that I eventually forget what I did).This post will walk through the motivation for automating listener tasks like this and a demo of how it works. It was designed to be used for administering speech intelligibility tasks in our lab, whereby participants hear an audio clip of somebody speaking, and must rate how intelligible (i.e., understandable) it was to them along a scale, for example, from “low” to “high.” It is adaptable to any perceptual experiment designed to be delivered in VAS form. I wrote a little script that runs a computerized visual analog scale (VAS) through Praat.This is Part 1 of a series of posts on writing a set of scripts to administer perceptual rating scale listening tasks using Praat software.
