If you experience that some words in LiterAACy are stuttering (e.g. you want would be pronounces as you w-want) then you need to uncheck read as you type in the Tobii Communicator sound settings:
-> Sound Settings
-> Read As You Type
-> Uncheck "Read each letter" and "Read each word"
As of LiterAACy version 184.108.40.206 you can choose this in the LiterAACy settings instead.
