What is accent neutralization?

Answer 1

A 'neutral accent' can be defined as a way of speaking (tone, intonation etc) where people from any geographical location is able to understand you, provided they know the language themselves! The 'neutral accent', in speech training refers to the module in which the participant is taught how to get rid of his/her MTI (Mother Tongue Influence). This kind of training is mostly used in businesses where interaction with over-seas customers/clients is a prerequisite.
