Praat scripts

Praat is an excellent program for linguistics research that lets you make acoustic measurements of speech patterns. Check out the Praat website. Below are some scripts that automate several tasks that can be done with Praat. (Katherine Crosswhite also has some great Praat scripts on her site.)

Formant Draw: Formant and pitch extracter that draws burg and sl formant tracks in the Praat picture window. This allows you to determine which method is best for your particular set of recordings.

Formant Extracter: Gets the pitch and formant tracks (burg or sl method) from a specified list of sound files and saves them to text files. Useful for synthesizing words with KlattWorks.

Word Chomper: Takes a single wav file and splices it into individual files based on the divison between utterances in the file. This is accomplished by analyzing the spectral intensity at precise intervals within the file. It is useful if you have a speaker read a list of words and then want to analyze each word individually. Decibel level of "silence" between words can be configured to suit your needs.
