I'm searching for languages which use a lot of different tones. The one with the most tones I found was Thai which has 5 tones. Are their tonal languages with use more distinct tones than thai?
Depending on how you analyze it, Trique may have as many as 15 tones, built from 5 pitch levels.
Lao has five tones (like Thai) in the south.
But Lao has six tones in the north.
... In the capital, Vientiane, which is supposed to set the standard for the Lao language, there has been an ongoing debate about whether the local spoken variety has five or six tones. I encountered teaching materials bluntly stating five, others bluntly stating six, and others mentioning the debate before arbitrarily choosing one analysis or the other before continuing.
