Hear2Read NG NVDA Addon Release Notes
| Date | Description |
| Apr 19, 2024 | * Added volume setting to control Hear2Read NG voice volume separate from the system volume * Spell out (NVDA Key+Shift or Ctrl+. key twice) and typing volume is also scaled just like the synthesised output volume * ASCII text with numbers is read completely in the English voice, numbers in ASCII context are no longer spoken in the regional voice * Updated support for NVDA 2024.1, as well as raised minimum supported NVDA to 2022.1 |
| Date | Description |
| Mar 19, 2024 | * Added support for spell out mode(NVDA Key + Ctrl + double tap '.') and typing. Note this is not the same as cursor movement. Currently, there is full support for Kannada, other languages will be added soon. * Corrected a bug where changing voices in NVDA could cause a crash |
| Feb 21, 2024 | * NOTE: The changes in this release are significant. Therefore, earlier versions of the Hear2Read NG Manager (1.1 and older) must first be removed (uninstalled) using Add-Remove function under Windows settings. * Starting with this release (1.2), the Voice Manager has been renamed to simply Manager and it manages all aspects of the Hear2Read NG Addon. * When you install 1.2, two icons are added on the desktop: -- Hear2Read NG Manager, and -- Hear2Read NG.nvda-addon (The naming convention is dictated by NVDA) * The Hear2Read NG Manager now updates all 3 parts of Hear2Read NG software for Windows: -- TTS Engine DLL (Dynamically Linked Library used by Windows OS), -- Language specific phonetic data, and -- NVDA Addon python module * When of any of these modules are updated, a prompt to restart NVDA is displayed so that changes come into effect * Because the DLL cannot be updated when it’s in use by NVDA, i.e. the selected synthesizer is Hear2Read NG, the Manager checks to find out if NVDA is using Hear2Rerad synthesizer. If so, the user is prompted to change to a different synthesizer temporarily, i.e. while the DLL update is installed. Once the DLL update installation is complete, the user is prompted to restart NVDA, and change back to the Hear2Read NG synthesizer. * The phonetic data and the addon python module can be updated while Hear2Read synthesizeris in use. Once the update is complete, the user is prompted to restart NVDA for the updates to come into effect. |
