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 8-bit .au sound files.

• Read and write raw 8-bit two’s-complement and offset-binary sound files.

Audio:

• 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).
