Baby Thallasodromeus low broadcast

The hatchling-late juvinile thallasodromeus low broadcast sounds really weird.
It sounds like the adult low broadcast, but extremely low-pitched.

Doing low-broadcast, or R on pc, makes the baby thal do an animation and sound.
But the sound is extremely low-pitched and unnatural sounding.

When doing low-broadcast, i expect to hear a baby thal, not an adult low tuned.
