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).
