COMPARE
 
Compare /f/ with /v/:
 
 
 
/f/…/v/…/f/…/v/…/f/…/v/...

Both /f/ and /v/ are labiodental fricative consonants. However, /f/ is voiceless and /v/ is voiced. When you pronounce /f/, your vocal cords should not vibrate. At the end of a word, the vowel before /f/ will be shorter than the vowel before /v/.
 
 

You can hear the difference between /f/ and /v/ in these words.
 
1. A. face, B. vase
2. A. fan, B. van
3. A. surf, B. serve
4. A. leaf, B. leave
5. A. shelf, B. shelve
6. A. safer, B. savor
 
 

Now, compare /f/ with /θ/:
 
 
 
/f/…/θ/…/f/…/θ/…/f/…/θ/…

Both /f/ and /θ/ are voiceless fricative consonants. However, /f/ is a labiodental consonant, and /θ/ is an dental consonant. You should pronounce /f/ with your upper teeth rubbing against your lower lip.
 
 

You can hear the difference between /f/ and /θ/ in the words below.
 
1. A. fought, B. thought
2. A. first, B. thirst
3. A. free, B. three
4. A. deaf, B. death
5. A. reefs, B. wreaths
6. A. whiff, B. with
