When you listen to spoken English, it very often sounds smooth, rather than staccato. One of the ways we achieve this is to link sounds between words.
Using a /r/ sound
For example, we use a /r/ sound between two vowel sounds (when one word ends with a vowel sound of 'uh' (as in the final sound of banana); 'er' (as in the final sound of murder); and 'or' (as in the final sound of or). The /r/ sound happens when the next word starts with a vowel.
A matter of opinion = "A matte - rof opinion"
Murder is a crime = "Murde - ris a crime"
For example = "Fo - rexample".
Using a /w/ sound
We use a /w/ sound when the first word ends in a 'oo' sound (as in you); or an 'oh' sound (as in no) or an 'ow' sound (as in now)
Who are your best friends? = "Who - ware - your ....."
No you don't = "No - wyou don't"
Now I know = "No - wI - know"
Using a /j/ sound
If you say the words "I" and "am" quickly, the sound between is a /ya/ sound. You can probably feel the sound at the back of your mouth, as the bottom of your mouth comes up to meet the top. The /j/ sound can link words which end with an /ai/ sound (I) or an /ey/ sound (may).
I am English = I - yam English
May I go? = May - jI go?
Consonant and vowel
When one word ends with a consonant (and the next begins with a vowel sound) use the final consonant to link.
An + apple sounds like a - napple.
Don't add an extra vowel after that consonant. So it's a - napple, rather than a - n - a apple.
Here are some more examples of consonants linking to vowels:
At all = "A - tall"
Speak up = "Spea - kup"
Right away = "Righ - taway"
Leave it = "Lea - vit"
School again = "Schoo - lagain"
