| Praat 6.4.55 Jan 15, 2026 |
Plug-ins: fixed a problem introduced in 6.4.52 by which menu commands with pause forms didn’t work. Scripting: fixed some problems introduced in version 6.4.52 concerning the interaction between pause windows and the Demo window. Opening TIFF files with Read from file..., as well as Insert picture from file...: rid a bug that would show monochrome TIFF files in four vertical stripes. Scripting: in pause forms, allow vector expressions as defaults in vector fields. Backslash trigraph for apico-postalveolars: ṣ (s.v), following Ladefoged & Maddieson (1996), who wanted to distinguish them from the more extreme retroflexes, i.e. apico-palatals such as ʂ (s.). |
| Praat 6.4.54 Jan 12, 2026 |
Windows: fixed a problem introduced in 6.4.52 by which Ctrl-mousewheel wouldn’t zoom in or out. Windows: better dotted or dashed lines. |
| Praat 6.4.53 Jan 10, 2026 |
Windows: support horizontal scrolling in three ways (two-finger swiping on the touchpad; left and right tilting of the mouse’s scroll wheel; turning the mouse’s scroll wheel while keeping the Shift key pressed). Sound: To PowerCepstrogram... now averages the power over channels instead of taking only channel 1. Scripting: fixed some problems introduced in version 6.4.52 concerning the interaction between pause windows and editor scripts. Scripting: runSubprocess and runSystem now support asynchronous, with which you can spawn a subprocess without waiting for it to finish. |
| Praat 6.4.52 Jan 3, 2026 | Windows: switch back to the faster version (version 6.4.50 was deliberately slower, so as to support Windows 7 and 8.1 for the last time). |
| Praat 6.4.51 Dec 31, 2025 | Windows: switch back to the faster version (version 6.4.50 was deliberately slower, so as to support Windows 7 and 8.1 for the last time). |
| Praat 6.4.50 Dec 30, 2025 | A bit of speech recognition via Whisper.cpp (adapted to Praat by Anastasia Shchupak), such as Transcribe interval in the TextGrid window. This works after you install one or more Whisper-cpp models, such as ggml-base.bin in the models subfolder of the preferences folder. |
| Praat 6.4.49 Dec 24, 2025 |
Open without error messages or warnings Kay files that have one sample too few or too many. EditDistanceTable: made readable and writable. |
| Praat 6.4.47 Nov 7, 2025 |
Sound: To LPC...: channel averaging by default. runSystem and runSubprocess should not divert a terminal window’s standard output. Repaired a bug from November 2014 by which writing a BarkSpectrogram to a binary file used an incorrect format. |
| Praat 6.4.46 Oct 21, 2025 |
ScriptEditor: made Run selection work again on Windows and Linux (bug since 6.4.44). Made pause windows (and perhaps Demo window) compatible with macOS 26 (Tahoe). |
| Praat 6.4.45 Oct 13, 2025 |
Made Picture window 60×60 inches (instead of 12×12). Windows: repaired a crashing bug in runSystem introduced in 6.4.44. Made progress bar writing compatible with macOS 26 (Tahoe). Repaired an old bug that could crash Praat when viewing a Table with 0 rows. |
