This block adds text to speech functionality to Moodle
It can be configured to use either the Google speech engine or the Microsoft speech engine. When added to a resource such as a page, it reads the contents.
There is also a lexicon to add pronunciations for words that it pronounces improperly. For example, it could possibly say I.V. for the text IV. It should, however, say 4. You could add in the lexicon IV = four and it willpronounce it properly.
A special thank you to Ryan Thomas who is the original author of this block.
