Thank you, but I still have a few questions about French pronunciation.

1. What is the correct pronunciation of stion? Our teacher pronounces Si jiong (Chinese Pinyin), shouldn’t it be Si tong?

question [k?stj?~]

gestion [?stj?~]

It is indeed "Si qiong". In fact, I think it is more like si qiong in Chinese Pinyin when I read it well. Really, believe me.

2. Is it necessary to distinguish the unvoiced and voiced consonants such as b and p? Is there any way?

Yes, it must be distinguished, otherwise it will be a joke.

For example

bus [bys] bus **** car

puce [pys] flea

If you can’t tell the difference, there is Ambiguity.

b is a voiced consonant that is separated by friction between the lips.

p is a voiceless consonant, but it is pronounced the same as b in Chinese Pinyin. For example, papa, you can directly pronounce it as "dad"

But the pronunciation of b in French, we are I have never cared about it in English or Chinese. The focus is on the friction of the lips, you can feel the trembling of the lips.

As for distinguishing these two sounds by hearing, it depends on practice. Listen more and practice more~

I hope it can help you~
