Pronunciation is the way word sounds are articulated. For example, American English emphasises its 'r' sounds, whereas Australian English does not. Some vowel sounds (the sounds of the letters a, e, i, o, and u) are also different.
Australian English – Will you get the car, honey?
American English – Will you get the car, honey?
Similarly, there are many Englishes around the world that will use ‘w’ like sounds in place of the ‘v’ sounds that you find in standard Australian English. Have a close listen to the following two examples, one from an Australian English speaker, and one from a speaker of Malaysian English. See if you can hear a difference in the way the speakers pronounce the first sound in the word ‘vomiting’.
Australian English – Were you vomiting last night?
Indian English – Were you [w]omiting last night?
