Introduction The data here are from Lao spoken by majority groups and minority groups in contact with the other Lao dialects. 1.1 Background When Lao dialects have long been in contact with each other, it is It has been generally accepted that worthwhile to investigate whether tone change is one property of language. variation and change have occurred. Some linguists working within particular linoui0 stic theories have therefore Gedney's concept of the tone box is attempted to accommodate the fact adopted. The tone data are analyzed that language changes and to find auditorily and acoustically. The explanations of the nature and causes typical distinctive tonal patterns of the of such change.

To determine how well these distinctive The fact of language change was tones have been preserved in Lao widely recognized in the eighteenth dialects in contact, they were then and nineteenth centuries when the compared to the ones in the Lao Neogrammarians among the historical dialects in this study. The tonal linguists attempted to explain the systems of the Lao dialects are also sound changes in Indo-European compared to the ones in the available languages. Such sound change was literature in order to find explanations said to have been motivated by for language variation. internal factors, i.e., mechanical and physiological factors like ease ?f The findings here reveal tonal articulation or simplification, that IS, variations and changes in both majority the movement toward what have been and minority Lao induced by both referred to as more "natural" or " less internal and external factors.

In the present paper, though language families and between one external factor, language contact, languages in different language has been emphasized, internal factors families, such as Tai, Mon-Khmer, have also been considered.3 Austronesian, Sino-Tibetan, and Mong-Mien. The present study aims to Language contact has been recetvmg describe tone variation and change in more and more attention (cf. , Weinreich, the Lao dialects4 spoken in some 1953; Clyne 1975 cited in Salmons, areas of Thai land where they are in 1992: 6; Ureland and Clarkson, l984; contact.
