Do you have a problem with these sounds? How do you say these words 'good' and 'would'? Are they the same?

/v/ & /w/

How to make the sounds :

To make the /v/ sound, put your upper teeth onto your lower lip. Use your voice as your breath passes 

through the teeth and lower lip. To make the /w/ sound, push the lips forward and say /u/, then let the tongue 

and lower lip drop. When you let the first sound glide into the second (usually a vowel follows), /w/ is 

produced. In this Unit, /w/ is not distinguished from /h/ (wail vs. whale)
