![]() ![]() That having been said, the inverse of the degg_oq measure computed by praatdet is usually more or less identical to the CQ_PM measure output by EGGWorks, while the inverse of the howard_oq measure is typically comparable to the EGGWorks CQ measure, depending somewhat on the threshold settings. I developed them primarily for my own use case, and in order to gain a better appreciation for the issues involved. I make no claims that the implementations here are correct, or that they will give the same results as some other set of EGG tools, etc. I haven't looked carefully at it, but it is no doubt worth exploring if you are interested in EGG. Update January 2020:Īs of version 6.1.04, Praat now includes built-in functionality for working with EGG signals. Praat comes with its own set of problems and I in no way claim it is superior to Matlab for this purpose however, I have learned a great deal about working with EGG signals in the process of developing these tools. ![]() I chose to work in Praat primarily because it provides a relatively intuitive and easy-to-use graphical interface for editing pulse trains. ![]() Eventually I decided that the easiest solution would be try and implement something similar myself. In the course of modifying their code to batch-process large numbers of files, I found myself wishing for a number of other modifications to the general peakdet workflow. This set of scripts was originally inspired by my attempts to use the peakdet tools developed by Nathalie Henrich, Cédric Grendrot, and Alexis Michaud. A suite of Praat scripts to determine the open quotient (Oq) and fundamental frequency (f0) based on the EGG waveform. ![]()
