Geo-linguistics is the study of language in relation to geography. Geo-linguistics is used to differentiate the areas where different varieties of the language are used. Geo linguistics has also been used to differentiate between the type of sounds found in the languages of different area. This new technology has allowed for easier linguistic research.

This new area of improvement in technology has been helpful to researchers and policy makers by helping to answer critical questions regarding language at International, national and urban levels (Cartwright, 2006). It has been helpful in media marketing as well. Knowing the different variations of languages spoken in different areas, advertisements could be created, catering to those varieties (Altman, Portilla, 2004).
