Based on surveys of the Nakhon Si Thammarat variety, Southern Thai may exhibit as many as nine distinct lexical tones, not yet taking into account other regional varieties. By comparison, Standard Central Thai has only five tones.
This richer tonal inventory contributes to a high degree of phonological complexity and dialectal diversification, which in turn supports a remarkable preservation of lexical variation across the region.
