What was new in 3.5?

## 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).
  • Keyboard shortcuts, text editor, help under question mark, etc.
