All scripts, by author

Petra Augurzky's script

• Word Chomper (multiple files): Variant of the Word Chomper script that processes multiple files in a single directory.

Chris Darwin's scripts

• Add two sounds with variable gains
• Add dynamic
• Change F0 and duration
• Change F0 and duration (dynamic)
• Comb filter
• Create matrix of plots
• Make stereo
• Make sine-wave speech
• Produce Shannon-type AM noise
• Spectral rotation
• Saberi reversal
• Vocal tract size change
• Vocal tract size change (dynamic)

Daniel Hirst's scripts

• Analyze intervals: Analyze a selected tier for a set of files and output duration, mean pitch, intensity, F1, F2, and F3.
• Diapason: Calculate note and accuracy (in semi-tones) from Hz with respect to reference pitch.
• Draw F0 & TextGrid: Draws a sound, F0, and one tier of a TextGrid.
• Manipulate duration: Manipulate the duration of a sound to values on an interval tier.
• Plugin miscellaneous: Adds a variety of functions to Praat: printing objects, realigning boundaries in a textgrid, drawing mathematical functions, and converting between Praat, Sampa, and Unicode phonetic transcriptions.
• Plugin Sampa2Praat: Plugin to convert between Sampa and Praat codings of the IPA.
• Separate speakers: Create a sound with utterances from a single speaker with different speakers separated onto different tiers in a TextGrid.

Heidi Kent's script

• Word Chomper (pitch-based): Variant of the Word Chomper script that uses the pitch tracker rather than the intensity tracker to segment utterances. Should work better with sound files that have background noise.

Mietta Lennes's scripts

• Align boundaries in two interval tiers
• Calculate segment durations
• Change sample rate of sound files

• Draw spectrum from selection
• Draw LPC spectrum from selection
• Label from text file
• Label quickly from text file
• Mark pauses
• Make textgrid from segment data
• Make textgrid from segment data endpoints
• Open all files in folder
• Play vowels draw formant chart
• Remove all objects
• Replace part of textgrid
• Save Finnish tier to phoneme string
• Save interval data to text file
• Save intervals to aiff sound files
• Save intervals to wav sound files
• Save labeled intervals to aiff sound files
• Save labeled intervals to wav sound files
• Save selection to sound and textgrid
• Save selection to sound and textgrid
• Total duration of labeled segments

Piet Mertens' script

• Prosogram: Program for transcription of prosody

Stephanie Packard's scripts

• Segmenter: Segments non-null labelled intervals in tier 1 of TextGrids.
• TextGrids: Annotates sound files to textGrids.

Jessica Sertling Miller's scripts

• Insert F0 markers in TextGrid
• Draw Object: draws waveform, spectrogram, pitch object, and TextGrid
• F0 Value: Measure F0 values of tones labeled in a tier
• Syllable duration: Measure duration of intervals (such as syllables) in a tier
• Alignment: Measure time alignment of tones in a tier
• Extract tones: Search tones in TextGrid and extract IP interval
• Extract syllables: Search tones in TextGrid and extract syllable interval
• Search for word in LongSound and extract intervals
• Formants: Measure F1 and F2 values at given time
• Open wav files and create TextGrids

Bert Remijsen's scripts

• Automatic detection of f0 turning points using MOMEL
• Calculate & check f0 tracks
• Producing time-normalized f0 tracks
• Script to extract duration measurements: There is also a Unix formatted version of this script.
• Script to measure & check formants (based on intervaltier)
• Script to measure & check formants (based on pointtier)
• Script to open files
• Script to open files, with pattern matching

Setsuko Shirai's scripts

• Create table: measures pitch, intensity, and formants every 10ms
• Vowel duration and formants using LPC object
• Vowel duration and formants using formant file

John Tøndering's scripts

• Move all boundaries in IntervalTiers to nearest zero crossing
• Move the boundary nearest to the cursor to the zero crossing nearest the cursor
• Label.man: labels a TextGrid according to a ManPage
• Draw FFT spectrum from selection
• Draw LPC spectrum from selection
• Extract voiced intervals
• Automatically extract voiced intervals
• Open all TextGrids in a directory
• Open all sounds or pitch tiers in a directory

Joe Toscano's scripts

• Formant Draw: available locally. 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: available locally. 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. (See also this version by Petra Augurzky that will process all files in a directory, and this version by Heidi Kent that uses the pitch tracker and should be able to handle background noise better.)

Pauline Welby's scripts
