You want to use Clicker in the Welsh language.
To do this, first download and install the Welsh synthetic voices from Welsh synthetic voices for text to speech I RNIB | RNIB. These voices can be used by educational professionals to support learners and by learners on their school and home devices.
Tips:
You do not need to include content in the Clicker Set – setting the language in the Clicker Set determines the language of Clicker’s Predictor and Spell Checker. The Clicker Set can be minimised using the show/hide Clicker Set button.
