Hi Agentzero,
I chose 9 letters based on research that has been done on what sounds are most common to the most people and languages (see: https://en.wikipedia.org/wiki/Phoneme and http://web.phonetik.uni-frankfurt.de/upsid_info.html). I also consulted with several linguists on this point. The consensus was that the 9 letters I chose were probably the right ones, with the possible addition of 's'. I debated adding 's', but did not in the end (or yet), since different people/languages tend to say 's' somewhat differently, people with lisps have trouble with it, and in general, I have the (possibly misguided) impression that it is a somewhat negative sound (like if you just say 'ssss' at someone - it sounds like a snake hissing. With just thirty words, 9 sounds should be enough to create words that are different enough from each other to be identifiable. I hope that makes sense. But I might add s at some point if more people feel as you do.
Hi Lushlala,
Thanks! I was going to call the language Mika, and then discovered its the name of a popular UK singer. I was looking for a name that was short and included some of the 9 sounds in the language. My wife suggested Kipi, and I liked the sound of it. Kipi is meant to be used by anyone anywhere. It can be used by two people who have no common language, or even by people who speak the same language, for fun. It can be used as an alternative for English in cases where one person is a native speaker and the other is not. It puts everyone on equal footing, since Kipi is no one's native language or everyone's (depending on how you look at it) I hope that answers your question.
Best,
Eli
