pitaWiSa
This is my most recent conlang. I began inventing it in February 2003. It is spoken by humans and a thinking, speaking species of birds who live on an isolated island. The island is fairly large, and for the most part humans live in the western half and speak human-only languages, while the birds (called WiSaWiSa - more about the capital letters later) live in the eastern half and speak their own languages. However, there is a region in the middle inhabited by both humans and WiSaWiSa, and that is where this language is spoken.
Phonology
The phonology of this language is a sort of compromise between the possibilities of human articulation and WiSaWiSa articulation. One of the most notable properties of this language is that it contains whistles as part of its sound system. The phonemic inventory of the language is as follows:
Consonants:
Stops (voiceless): p t k
Continuants (normal): w s
Continuants (whistled) W S
The two whistles are: W, a "normal" labial whistle produced by rounding your lips, and S, an alveolar whistle. It doesn't involve lip-rounding, and is very close to an s in the way it is made, though the tongue is perhaps a bit more forward.
Vowels: u i a
Syllable structure:
Only very simple syllables are allowed. Every syllable must have an onset (consonant at the beginning), and codas (consonants at the end of syllables) are not allowed. Diphthongs and long vowels are not allowed. The only combinations of two consonants that are allowed at the beginning of a syllable are a stop followed by a continuant (normal or whistled). This gives a total of 57 possible syllables.
