Something to write into Danny Wier's guestbook ;-) It has been observed that in natlangs, there is about 50% redundancy in the number of phonetic features (place and manner of articulation, voicing, etc.) that are used to distinguish phonemes. For example, with six features one could distinguish up to 64 phonemes, but languages which actually use six distinctive features usually only have about 30 phonemes or so. The remaining combinations simply don't occur. English, for example, has /b/, /p/ and /m/, but no /m_h/ (that's a voiceless /m/). And so do lots of other languages in the world. This means that if a listener gets just one feature wrong, chances are that he ends up with a non-phoneme which he can easily correct from the context, and doesn't blunder into the other half of a minimal pair.

Looks like a primitive electronic display device, or a holy or magical symbol... neat idea to derive characters from such a template.

What does the last figure represent? Jörg. .
