i dont know in praat itself, but many scripts are available online given by scientists working in different phonetic -phonology labs

1. The GSU Praat Tools package is available for free down-

Mayada Nageeb Al-Maktary

Thank you very much

Leônidas Silva Jr.

Hello Mayada Nageeb Al-Maktary !

Suresh Thontadarya suggested nice material.

Considering a number of different statistical methods and purposes, what are you working with more specifically? I mean, what is your research about?

Thank you for your consideration of my inquiry. I would like to know how different Praat statistical techniques can be used to investigate speech disorders.

Hello!

Maybe the best way to run test statistics such as, Analysis of variance (ANOVA, a family of tests widely used), is from specific softwares like MS Excel, SPSS amog others, and languages such as, R or Python (which particularly I use).

Praat is widely used for acoustic analysis. Once you have the acoustic features (for instance, shimmer, jitter, HNR, H1 - H2 among others - commonly used to investigate speech disorders) returned from Praat, then it is time to choose a statistical technique the fits your analysis (like mean comparison between groups with/without disoreders for example).

This is a praat script that extracts a great number of acoustic characteristics from speech (there are speech disorders researches in development using this code: https://github.com/leonidasjr/SpeechRhythmCode)

If you have questions about these measures or how to run the script, please just let me know.

I hope that this could help.

Good luck!

I appreciate you sharing this information.

Is the "https://github.com/leonidasjr/SpeechRhythmCode" link intended to give users access to a specific GitHub repository? I was unable to understand how I could profit from it.

Yes. As you click, go to my repository and you may download the files (see attached).

Just let me know if you could access

Could you please tell me how to create a username that meets the requirements of your platform? I tried several times, but it was never accepted.

Excuse me, another question: is there a video that shows how to use this platform effectively?

If the platform you mean is the "GitHub", yes. Here: "Downloading Files from GitHub on Windows - Step by Step Tutorial" https://www.youtube.com/watch?v=N_bDcwL-R04

You just need to download the files (please, see them in the attached screenshot I sent above) and run them on Praat:

1. the script - '.psc' file;

2. the audio - '.wav' file, and

3. the TeixtGrid - '.TextGrid' file)

By the way, I have made some updates and did not tell you in the last message (sorry for that). Now the files are "fresh" in the repository. Please, re-download them.

If you need some help to run the script, you can either:

4. Read the User manual in the repository, or,

5. check the videos on this YouTube channel caalled "Liaten Lab" : https://www.youtube.com/@listenlab_umn

Good luck (let me know if things are working)

Thank you very much.
