Last versions key changes:

16/12/2025

• Created (replaced) a git repository with the chatterbox code from scratch.
• Updated most of the git repository code, syncing with the official 1.0.6.
• Completely replaced the voice tempo (speed) adjustment code:

• Processing is now performed with local sox (downloaded and unpacked locally into the neural network folder).
• No echo, no metallic voice feedback.

• The update no longer updates configuration files (they are simply missing from the update).

11/12/2025

• Added a local ffmpeg. Downloaded during a full installation or this update, it no longer depends on the system ffmpeg.
• Switching between language emotion presets will no longer replace the text with the example text.

9/12/2025

• Fixed stress placement using the built-in Ruaccent mechanism (using the RUStress button). More accurate stress placement. - Added processing of additional dictionary files from the /dicts folder. Automatic file encoding detection. WARNING! LARGE DICTIONARIES LEAD TO LONG LOADING AND STRESS PROCESSING!!! NO CLAIMS AGAINST ME!!!
• Changes have been made to the language emote presets - they no longer switch languages, but stay with the one you generate.

08/12/2025

• Reference audio is now up to 10 minutes long
• All 24 languages ​​are already enabled and available
• Automatic saving of the last used language for the next engine launch (no need to re-select the last used language)
• Stress marks in Russian can now be added directly in the neural network using the RUStress button
• Added a local dictionary of stress marks for Russian and other languages. Simply edit the accent_fixes.yaml file, which already contains examples, as the Ruaccent dictionary I use is the best available, but not perfect. Ease of use.
• Automatic saving of output audio files to the /outputs folder. Changing the audio compression format changes the audio file format. There is no local cache of audio files.
