These may not exist in 4.13. Your speech synthesizer has to support these characteristics. The preset voices may be a way to change these parameters. Leave the note. I've not seen defined in any synthesizer.
Speech synthesizers do have a concept of richness.
I share Mickey's concern. It would be nice to copy the glossary reference into our own glossary. Should we copy the terms in UAAG 1.0. These checkpoints are for designers choosing which speech technology to include in their product. Solution for repair text should not be minimal requirement.
