同大家分享L的发音 - 读“Pronunciationshop”有感

1
"Been" 中的元音，我一直认为是发长音/i:/，但应该是发短音/i/.
2
'l'在词尾及音节末时，其发音方式同'l'在词首及元音前的发音方式一样，发音位置不变，只是把舌前部上抬，舌尖抵住上齿龈，注意嘴唇要保持不变，尽量不要随着"l"的发音变小(Your comments are welcome)。

I've recently listened to the audios of a DVD recording from the pronounciation training program by Paul Gruber (http://www.pronunciationworkshop.com/)

Two points stood out in my mind, one is the pronunciaiton of the word "been", the other is the pronunciation of sound "L".

"Been" should be sounded as /bin/ based on Paul and it seems like this from the dictionary, but I thought that it was sounded as /bi:n/。 What do you think this word should be labled, /bin/ or /bi:n/ ?

For the sound of "l" at the end of a word, the pronuncition manner is the same as when sounding "l" at the beginning of a word, but rise up the tip of the tongue and put behind your top teeth, the mouth(lips) positions remain unchanged.

Manner when sounding "l" at the beginning of a word:
Mouth should be wide open;
Jaw should be down.
Tongue should rise up and push behind your top teeth.
