/f/ vs /v/



/f/ and /v/ are two labio-dental fricative sounds.

A) DESCRIPTION: the lower lip makes light contact with the upper teeth, so that the escaping air produces friction. For /f/, the friction is voiceless, whereas for /v/, the friction is voiced.

B) SPELLING:
/f/: "f, ff, ph, gh". For example: fork, off, physics, enough, nephew.
/v/: "v, f". For example: very, of, leave.

C) IDENTIFY THE SOUNDS:
C.1. Open this chart, click on FRICATIVE, then click on /f/. Play the video with the mouth picture. Then play the video on the right.
C.2. Watch this video:

Now answer the following questions about these two sounds:
C.2.1. What's the same in both sounds?
C.2.2. What is the difference?

D) PRACTICE:
D.1. Open this chart again, click on FRICATIVE, then click on /f/. Play the video with the mouth picture. Then play the video on the right. Listen and repeat the sound and words. Do the same with /v/.
Now watch the video again in order to practice and repeat the sounds and words.
D.2. Finally, try these tongue twisters:
-"My wife gave Mr Snipe's knife a wipe".
-"Violet bet a bat her best vest".
Hope you enjoy it!
