Which language(s) has the most phonemes?

…and which has the fewest?

Most phonemes: Khmer (spoken in Cambodia)
Fewest phonemes: Rotokas (a language spoken in Papua New Guinea)

Sad thing is, I didn’t even have to open a book for that one. However, I cannot give you exact numbers.

An interesting tidbit is that Quebecois French has among the largest number of vowel phonemes (or was it allophones?) of any language in the world.

I thought Hawaiian had the fewest with 13. Anyone know how many Rotokas has?

Probably allophones. Just compare the ‘o’ in Québécois “comme” and “alors” and “coquin” etc. And there are some languages that have a lot of vowel phonemes (German and English are two good examples).

Québécois is notorious for being a very rapidly spoken language. For instance, one can express the phrase “I am at John’s house” in 3 syllables “Chu chez Jean” compared with, say Spanish “Yo estoy en la casa de Juan” which has 9 (although most Spanish speakers will omit the initial “yo”). It is because of this efficiency that I like to speak Québécois.

I did a little research. Rotokas has 6 consonant phonemes and 5 vowel phonemes, making just 11 phonemes.

How many phonemes does Khmer have? !Kung is supposed to have 96 consonant phonemes, and I don’t know how many vowel phonemes.

I like it too. The other day I realized the following:

Qu’est-ce qu’il y a? (What’s the matter?) = /kEskij@/

/k/ = que
/E/ = est
/s/ = ce
/k/ = que
/i/ = il
/j/ = y
/@/ = a

One phoneme per morpheme. Seven morphemes in three syllables. Câlice!

I think you’re thinking of number of letters in the Hawaiian alphabet.(?)

I am highly skeptical of this alleged efficiency. Though I don’t have a cite at the moment, I distinctly recall from my undergrad linguistics classes that spoken language conveys, on average, a certain number of ideas per second. The difference between the averages for any two languages is negligible – that is, there is very little deviation from a universal mean. Thus, while you may slur out “Chu chez Jean” in time t, a native Spanish speaker will fire off his corresponding nine-syllable monstrosity in time t plus or minus epsilon. It may seem rapidly-spoken to us, but for the Spanish speaker it is his normal pace.
