Intrigued by an article wherr they keep telling you to use AAC but never say what AAC means? Unless I missed it? Easy to work out from context I guess. Anyway expensive IS a great word.
Jamie And Lion (aka, SpacedOutSmiles)‘Expensive’ is such a great word for speech. In many situations I can make words work, but the energy cost can be catastrophic. Places with loud background music or other people talking nearby are good examples. Zoom meeting with audio lag etc.
