Praat 3.5, 27 May 1997

New editors:

•  TextGridEditor replaces and extends LabelEditor: edit points as well as intervals.
•  AnalysisEditor replaces and extends PsolaEditor: view pitch, spectrum, formant, and intensity analyses in a single window, and allow pitch and duration resynthesis by overlap-add and more (would be undone in 3.9.19).
•  SpectrumEditor allows you to view and edit spectra.

Praat shell:

•  History mechanism remembers all the commands that you have chosen, and allows you to put them into a script.
•  ScriptEditor allows you to edit and run any Praat script, and to put it under a button.
•  All added and removed buttons are remembered across sessions.
•  ButtonEditor allows you to make buttons visible or invisible.

Evaluations:

•  In his 1996 doctoral thesis, Henning Reetz compared five pitch analysis routines; Sound: To Pitch (ac)... appeared to make the fewest errors. H. Reetz (1996): Pitch Perception in Speech: a Time Domain Approach, Studies in Language and Language Use 26, IFOTT, Amsterdam (ICG Printing, Dordrecht).

Documentation:

•  140 more man pages (now 330).
•  Tables and pictures in manual.
•  Printing the entire manual.
•  Logo.

New types:

•  Labelling & segmentation: TextGrid, IntervalTier, TextTier.
•  Analysis & manipulation: Analysis.
•  Statistics: TableOfReal, Distributions, Transition

File formats:

•  Read and write rational numbers in text files.
•  Read 8-bit .au sound files.
•  Read and write raw 8-bit two's-complement and offset-binary sound files.

Audio:

•  16-bit interactive Sound I/O on Mac.
•  Record sounds at 9.8 kHz on SGI.

New commands:

•  Two more pitch-analysis routines.
•  Sound to PointProcess: collect all maxima, minima, zero crossings.
•  PointProcess: set calculus.
•  TextGrid: extract time-point information.
•  Compute pitch or formants at given time points.
•  Put pitch, formants etc. in tables en get statistics.
•  Many more...

Macintosh:

•  16-bit interactive sound I/O.
•  Fast and interpolating spectrogram drawing.
•  Phonetic Mac screen font included in source code (as a fallback to using SIL Doulos IPA).
