Hear2Read Indic Language Synthesizer is available in NVDA Add-on Store

If you have installed other NVDA Add-ons from the NVDA Add-on store then use the same process. The process is documented in NVDA User Manual section 13.

Following is a brief overview of the installation process:

  1. Select Add-on store under Tools through NVDA menu (NVDA key+N, or clicking the NVDA icon in the taskbar tray).
  2. On the Add-on store screen, select “Available add-ons” tab. It will display a long list of all add-ons available in the store.
  3. Type hear2 in the search box. It will now display only Hear2Read Indic Speech Synthesizer in the Available add-ons list.
  4. Right click anywhere on the line displaying Hear2Read Add-on to brings up a drop down menu. We recommend positioning the cursor in the status column.
  5. Click on the first entry (Install) in the drop-down menu. If the cursor is in status column, it will quickly change to Downloading and then to “Downloaded, pending install”.
  6. Close the Add-on Store window. NVDA will start installing the Add-on with a message and a short beep. The installation will complete pretty quickly. It will then display (and speak) the message advising that NVDA needs to be restarted for the Add-on to be active.
  7. After NVDA restarts and displays the welcome message, it will display a message indicating that no Hear2Read voices are installed and asking if you want to install a Hear2Read voice.
  8. Once you select Yes (for installing Hear2Read voices), it brings up Hear2Read Indic Voice Manager that lists all the languages supported by Hear2Read. You can download one or more Hear2Read voices by double clicking on the language name. After each voice is download, the Voice Manager will ask if you want to restart NVDA. Select Yes, if you do not want to install anymore voices. Select No, if you want to install another voice.
  9. After NVDA has been restarted, you can use Hear2Read synthesizer to read Indic text by selecting the language under speech settings just as you do for any synthesizer.

Note: Users updating to new version published in the Add-on store from an older version downloaded from this website, should uninstall the older version using Windows Add/Remove program. This will remove both Hear2Read shortcut icons (NG Manager and NG.nvda-addon) from the desktop.
