# Praat Signal Analysis

Some utility scripts that could be useful in signal analysis with Praat.

Download the scripts of this page via [GitHub](https://github.com/liri-uzh/svt/tree/main/praat_signal_analysis).

Check out [Praat script guide](/svt/general-info/praat-script-and-plugin-guide.md#praat-scripts) for the tips of using Praat scripts.

This script measures speech rate by calculating the number of amplitude envelope peak points per second.

Select a Sound object and run this script. A Praat Info window will pop up showing the result.&#x20;

## function\_measureSpeechRate

This script measures speech rate by calculating the number of amplitude envelope peak points per second. The script is based on `function_createPTPtier.praat` to show the peaks.&#x20;

Select a Sound object containing speech and run the script. A Praat Info window will appear showing the result, and a TextGrid will be created and viewed together with the Sound object to show details of the peaks.&#x20;
