I disagree. Their tone higher and many terms they use are uniquely Malaysian. ie. such 几夠力, 几多錢, 几有空。one can distinguish a Singaporean from a Malaysian from the way they talk.
their accent sound funny,its like they forgot how to speak Chinese,only learn how to speak malay,then like the old fart at 25 years old learn how to speak Chinese,then sound like malay trying to speak Chinese.
