Page "Tone (linguistics)" Paragraph 4

There are numerous tonal languages in East Asia and South East Asia, including all the Chinese languages ( though some such as Shanghainese are only marginally tonal ), Vietnamese, Thai, and Lao.

Some East Asian languages, such as Burmese, Korean, and Japanese have simpler tone systems, which are sometimes called ' register ' or ' pitch accent ' systems.

However, some languages in the region are not tonal at all, including Mongolian, Khmer, and Malay.

Of the Tibetan languages, Central Tibetan ( including the dialect of the capital Lhasa ) and Amdo Tibetan are tonal, while Khams Tibetan and Ladakhi are not.
