Tim: Hi. I'm Tim and this is my pronunciation workshop. Here, I'm going to show you how English is really spoken. Come on, let's go inside. You see this? This is my lunch - well, either that, or it's some cat food. Anyway, do you know what we call this container? It's a can, right? Now this has the same spelling as the modal 'can', and the same pronunciation, hasn't it? Or has it? Listen carefully when we ask some people in London how many languages they speak.

Tim: In fluent everyday English, when the modal auxiliary 'can' is unstressed, its pronunciation changes to /kən/. 'I /kæn/ speak four languages' becomes: 'I /kən/ speak four languages'. This is what's known as a weak form and it can occur in questions as well. Here are some more examples.

Examples
Can you help me bring in the shopping, please?
I can swim further than I can run.
You can succeed if you work hard.
How far can you throw a tennis ball?

Tim: Right, so you've heard the examples, and now it's your turn. Are you ready? Listen and repeat.

You know what? That is not bad. Salmon? Rabbit? Mouse?
