haha i know these following sentences is the pronunciation of cantonese, cuz i am cantonese:)
nay hoh =hello =你好
nay hoh mah?=how are you?=你好吗?
And these are the pronunciation of manderin
Nee Hau Mah?=how are you?=你好吗？
i think the sentenses（pronunciation）can help you speak Chinese ,it`s convenient. But if you want to learn Chinese systematically, you may need to start with pinyin
