I am doing some research on a manuscript which I need to identify the language. My hypothesis is that it is written in phoneme by someone who does not understand the language. Spoken aloud, one that does understand it can guess context and meaning of sounds. Akin to Marcel Duchamp's LHOOQ paintings with its title written in "French phoneme"...
Is there such a thing as a database of phoneme's (x-axis) occurrence (y-axis) across many languages (old French, Occitan, old English, Gaelic, etc) ???
upsid or phoible are close but they do not show occurrence of individual phoneme for a given language, only total number of phoneme.
Any hints will be appreciated.
ps. I was able to get a distribution of phoneme for English and French. Processing corpus of text such as in Gutenberg.org would provide words in many languages but not the phonemes (or sound within the words)... syllables might be more appropriate that phoneme... but then there is no list of syllables for languages... or is there ???
