我想學英文併聲.又唔想上課,我想問買書學得唔得嫁??

There are learning materials in the market that you can buy to learn phonology. I recommend you to go for those come with accompany CDs, so that you can listen to sample pronunciation. However, my personal experience tells me that those learning materials can only teach you theories, you do need a teacher to guide you through the process of learning. It is hard to notice one's own mistakes, this is particularly true when we come to learn phonology. It is not about being smart or not, books in the market are published at different levels, it is not easy to find one that can meet all your needs, on the other hand, a teacher is flexible, she/he can find out which areas he/she should spend more or less time on. So...I reccomend you to borrow some books from the library to learn some concepts first and then find a teacher to give you extra support. If you are willing to do some self studies, I don't think you will need many lessons.

Actually I am learning phonology at the moment. I am using the text book, 'An Introduction to the Phonology of English for Teachers of ESOL'. It is written by my lecturer, Tim Graham and his friend, Ray Parker (1994,2002,2005), published by ELB Publishing. It comes with an accompany CD. The language used is not too difficult to understand and I found it quite useful. However, I live in the U.K., so I don't know if you will be able to get it in H.K. Anyway good luck to your studies
