Akat Amnuai district, Sakon Nakhon province, Thailand as well as Laos. Yoy has a decimal system. Counting in Yoy is similar to what in Thai and Lao. It is done in decimal system with basic terms /nɯŋ1/ ‘one’, /sɔ:ŋ3/ ‘two’, /sa:m3/ ‘three’, /si:5/ ‘four’, /ha:5/ ‘five’, /hok2/ ‘six’, /tɕet2/ ‘seven’, /pæ:t5/ ‘eight’, /kaw5/ ‘nine’, /sip2/ ‘ten’, /saw2/ ‘twenty’, /hoj4/ ‘hundred’, /pan2/ ‘ thousand’. Please note that the number /nɯŋ1/ ‘one’ can be replaced by /-ʔet2/ in a final unit of the number of complex number that is larger than one unit; for example, /sip2ʔet2/ ‘eleven’, /sa:m3sip2ʔet2/ ‘thirty one’, /hoj4ʔet2/ ‘one hundred and one’.
