Startling the baby ?

Meagan
Ok so my husband like to lay and and talk to our baby girl, well yesterday he put his face to my stomach and made a light roaring sound and she moved.. I just figured she was just moving to move. Well tonight she was really close to the surface and he did the same thing again and the same thing happened except more intense then before, I'm 17 weeks is it possible for him too be startling the baby? Or just responding to vibrations?
