Pronunciation: Assimilation of /d/ and /b/

Tim’s back in his pronunciation workshop. This time he’s finding out what happens when one word ends in /d/ and the next begins in /b/ - and talking speed boats with some Londoners...

Now, do you know the word speeb? No, of course not because it’s not a real word. Or is it? Listen to some people in London talking about this. Voxpops It’s a speed boat. Speed boat. Speed boat. Speed boat. Speed boat. Tim Now, the word speed ends in the sound /d/, doesn’t it? Well not always. Watch and listen again, what sound can you actually hear? Voxpops It’s a spee? boat. Spee? boat. Spee? boat. Spee? boat. Spee? boat. Tim In everyday speech, when we’re speaking fluently, if one word ends in a vowel sound followed by a /d/ and the next begins in a /b/, then the /d/ changes to a /b/ and then merges with the /b/ from the following word. So ‘speed boat’, becomes ‘speebboat’. Watch again, this time in slow motion. Look at the mouth shape. Can you see /d/ or is it just /b/? Voxpops Speeb boat. Speeb boat. Speeb boat. Speeb boat. Speeb boat. Tim This is another case of assimilation. Here are some more examples. Examples My son is a really good boy. I’m sorry if I was rude before. My car had to be towed back to the garage. You should buy him a present. Tim So, you’ve heard the examples, and now it’s your turn. You know the drill. Listen and repeat. Examples My son is a really good boy. I’m sorry if I was rude before. My car had to be towed back to the garage. You should buy him a present. Tim Well done. And remember, if you want to learn more about pronunciation, then please visit our website, . And that is about it from the pronunciation workshop for this week. I’ll see you soon. Bye bye! Aah – you know, one day I’m going to get one of these. Not a toy, obviously, but the real thing. My dad promised. He said if I was a good boy he’d buy me a boat. That was quite a long time ago actually. I think I was five years old – and I have been a good boy. Maybe he’s just forgotten. I’m never going to get my speed boat, am I?
