Till 2 years my daughter spoke only few words. And she started talking later. So, I don't think you need to worry.

Hi Anita nothing wrong it getting him tested. Early interference is good.

Recognise things but speak don't meaningful word

Anita, as the baby is already 2 years old you should take him to the speech therapist. And if there's some recognising issue that too needs evaluation. Don't worry at all...These things are verry normal.
