"It's the language everybody can be assumed to speak, as a baseline on which to build other ideas and concepts.  All the phonemes are a minimum distance away from each other that guarantees people with slightly less acute hearing can understand it when spoken under slightly adverse conditions.  In-between phonemes that are possible to pronounce, but potentially difficult to hear correctly, are then reserved for constructing 'conlangs', constructed languages, that use 'Baseline' as a baseline.  The only one of those I know is 'Default-Conlang' which has a lot of subtle in-between syllables, so that children will hopefully grow up to be able to distinguish 'conlangs'; you can teach your child a different conlang but it has to be conlang-phoneme-complete."
