回複：回複：有沒有有效的口腔肌肉訓練法？

Quite agree with Palmtree's recommendation.
The two links in BJ#2's for phonetic transcription practice are really useful -- keep practising the consonants and vowels will be good excercise for mouth musceles -

Below are some some words on mouth muscle practise (I don't have the source any more, sorry), but I didn't excersie it at all. Just for your reference (as said before, if you've mastered the English vowels/consonants, your mouth muscles are already well trained).

1、口的開合練習

張嘴象打哈欠，閉嘴如啃蘋果。開口的動作要柔和，兩嘴角向斜上方抬起，上下唇稍放鬆，舌頭自然放平。做這個練習，克服口腔開度的問題。

2、咀嚼練習

張口咀嚼與閉口咀嚼結合進行，舌頭自然放平。

3、雙唇練習（這個練習還有助於女孩子美唇啊，嗬嗬）

雙唇閉攏向前、後、左、右、上、下，以及左右轉圈

雙唇達響

4、舌頭練習

舌尖頂下齒，舌麵逐漸上翹

舌尖在口內左右頂口腔壁，在門牙上下轉圈

舌尖伸出口外向前伸，向左右、上下伸

舌在口腔內左右立起

舌尖的彈練，彈硬齶、彈口唇

舌尖與上齒齦接觸打響

舌根與軟齶接觸打響
