[Ashvini]

Hi Teacher,

is this sentence is correct?
>>I tried to listen CNN.

In MS word, I am getting verb confuse error at word "listen".

One more question,
I heard from my friends and colleagues that my articulation is not good. I want to improve my articulation in english sentences.

can you please guide me what should I do to improve this?

Regards,
Ashvini

I tried to listen to CNN.

As for your articulation, Demosthenes famously practiced oration with a mouthful of pebbles.
