I apologize for the answer to a different question that was posted inadvertently here
Speaking can be very variable in different children.
However at this age, some amount of speech including specific discrete words should be present
I would recommend a hearing evaluation
Most likely this would be a normal variation
BUT I would urge a hearing screen.
If that is normal and there is a family history of speech delay, then it would be appropriate to wait for at least a few more months
Please let me know if you need more inputs
