The objective aims to compare the speech acts of final particles in Kham Muang language which was influenced from social factors about gender. The concepts of analysis are Pragmatics and Speech acts. The result of the study shows that the final particle of Kham Muang language is divided into 4 groups; 1) Representative (30.8%), 2) Expressive (25.84%), (3) Directive (23.40%), and (4) Commissive (20.58 %) respectively. Gender has an influence on Kham Muang final particle speech act. For Female, Representative is most found (34.68%), Expressive (29.30%), Commissive (19.91%), and Directive (16.11%), respectively. For Male, Directive is most found (31.37%), Representative (25.25%), Expressive (22.06%), and Commissive (21.32%), respectively.
