Question: My stem's planted firmly where I am allotted.
My tail is wavy and my face is quite blotted.
I relay much emotion though flatly I'm spotted,
And I grow half my size whenever I'm dotted.
I can speak any language, yet utter no words.
I'm no seed, yet I am well known among birds.

I can say deaf but not red, bed but not sled.

I live on a highway that's structurally sound,
Where you might see my friends accidentally bound.
It has many lanes, and also long lines.

The key is to measure before you've begun.

What am I?
