SpeechSynthesizer: repaired an old bug whereby Get phonemes from text... could increase the duration of a subsequent Play (or To Sound...). SpeechSynthesizer and TextGrid alignment: repaired a bug (existing since 6.4.18) whereby clause and word tiers would be empty. TextGrid window: disambiguated Command-F5 (now Option-F5 for Get minimum pitch; likewise, Option-F8 for Get minimum intensity). Calling Praat from command line: reenabled --pref-dir= option. |

SpeechSynthesizer and TextGrid alignment: solved an eSpeak-internal bug that caused some rare long phoneme codes to be handled incorrectly. Scripting: padLeft$(), truncateLeft$() and padOrTruncateLeft$(), and their Right counterparts. |
| Praat 6.4.17 Aug 9, 2024 |
Spectrogram: Paint: solved a bug that could cause Praat to crash if the time domain was smaller than that of the Spectrogram. ScriptEditor: Run selection can call procedures outside the selected text. Audio files: can open Polyphone (Shorten) files. |
| Praat 6.4.16 Jul 29, 2024 | Windows: make command-line output visible (new on ARM64, was lost in 6.4.14 for Intel64 and Intel32). |
| Praat 6.4.15 Jul 27, 2024 | Distinguish between pitch ceiling (flat) and pitch top (curved ceiling), mainly because of their different meanings. |
| Praat 6.4.14 Jul 24, 2024 |
Pitch menu (in e.g. Sound or TextGrid window): separate settings for four pitch analysis methods. Formant analysis: faster on all systems. ARM64 Windows: worked around a compiler bug that caused incorrect window sizes. Pitch analysis: faster on Windows (Intel64 and Intel32). Windows: better fonts and background colours (perhaps dependent on language settings). TextGrids: Concatenate: guard against some incorrect TexGrid files. |
