Praat: baixar versions anteriors

- Corpus: extract TextGrid, Sound, speakers Table.
- CGN Corpus: extract components, education regions.
- Sound: To CPP...

- MacOS Tahoe: support making menu choices or turning windows to full screen if a script is paused (by the Demo window or the Pause window), as on earlier MacOS versions and on Windows and Linux.
- 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).
- Windows: better dotted or dashed thick lines.
- Sound: To PowerCepstrogram... now averages the power over channels instead of taking only channel 1.
- 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.
- Mac and Linux: made Insert picture from file... work for PDF files again (bug since 6.4.28).
- 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.).
- Linux: prevented a crash when a “barren” edition tried to run runAllTests_batch.praat.
- Scripting: runSubprocess and runSystem now support asynchronous, with which you can spawn a subprocess without waiting for it to finish.
- Scripting: randomImax.
- Scripting: in pause forms, allow vector expressions as defaults in vector fields.
- Scripting: syntax check against duplicate procedure names.
- Scripting: no longer any limits on the number of labels and procedures.

- 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).

• 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 (from https://huggingface.co/ggerganov/whisper.cpp) in the models subfolder of the preferences folder.

- Open without error messages or warnings Kay files that have one sample too few or too many.
- Linux: the standard Linux edition now runs equally well on Ubuntu, Fedora, Debian and Centos.
- EditDistanceTable: made readable and writable.

- Linux audio: recognize JACK devices (next to the already recongized ALSA devices).
- Linux fonts: support for the Charis 7 font, as on macOS and Windows.
- OTGrammar: non-negative maximum entropy learning.
- Debug option at start-up from command line, e.g. --debug=58.

- 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.

- Made pause windows (and perhaps Demo window) compatible with macOS 26 (Tahoe).

- Made Picture window 60×60 inches (instead of 12×12).
- Windows: repaired a crashing bug in runSystem introduced in 6.4.44.

- Made Info window writing compatible with macOS 26 (Tahoe).
- Made demoShow compatible with macOS 26.
- Made ScriptEditor menus reachable on macOS 26 when the script is paused.

- Calling Praat from the command line: the new switch --send-or-form sends a script to a different already running GUI instance of Praat, like --send does, but takes no arguments (except for the name of the script file) and presents a form on the screen if the script has a form in it.
- More detailed manual page for fileNames$# ().

- Recognize more OGG sound files.
- Recognize the pre-2025 sendpraat message on Windows again (compatibility with Elan 7.0).

- Removed a bug that caused Praat to crash on Sound: To Formant (robust)....

- Faster computation of spectrograms and formants (because of multithreading).
- Full awareness of processors with up to 400 physical threads (i.e. 200 or 400 cores).

- Backslash trigraphs for tone symbols: a᷄ (a\-'), a᷇ (a\'-), a᷅ (a\`-), a᷆ (a\-`), a᷈ (a\rf), a᷉ (a\fr).
- Other backslash trigraphs: d̼ (d\mv), d̫ (d\wv).

- Read Sound and adjacent annotation files (TIMIT)...: if you open any sound file from the TIMIT corpus, the annotation files with the same name in the same folder are interpreted as a TextGrid and opened as well.
- Read Sound and adjacent annotation files (Buckeye)...: if you open any sound file from the Buckeye corpus, the annotation files with the same name in the same folder are interpreted as a TextGrid and opened as well.

- Backslash trigraphs for diagonal arrows: ↗ (\NE), ↘ (\SE), ↙ (\SW), ↖ (\NW); the first two of these double as tone symbols.

• EEG window: repaired a bug that caused Praat to crash when clicking View & Edit.
• Windows Demo window: made Escape key available to demoKey$() (this had been a bug since the beginning of the Demo window, i.e. since May 2009).
• Read TextGrid from ESPS label file...
• Repaired a bug that could cause Praat to crash on pitch analysis when a part of the sound was constant.
• Insert picture from file...: the picture is now embedded into Praat picture files; this also solves a problem with file paths that surfaced when a script called another script that inserted a picture.
• Photo: Save as PNG file...: repaired a bug that caused a crash on the Mac.

- Graphics text: better pipes and slashes.
- Windows for ARM64 processors: removed a bug whereby dynamic menu deletion could crash after a sound was played in the Demo window.

- Scripting: fixed a bug that could cause Praat to crash when an unknown choice was given to an option menu.
- MelSpectrogram: fixed a bug that could cause Praat to crash if a mel value was negative.
- DataModeler: improved confidence limits on estimated model parameters.

- The command Sound & Pitch: To PointProcess (cc), which is also used when computing the times of pulses in the Sound window, could cause Praat to freeze when the pitch ceiling (and the measured pitch) were very high; this problem existed since at least 2001.
- eSpeak: new version, with e.g. Tigrinya.
- Support for 119-dpi graphics on Windows.
