Lately, I have been working on the way a group of humanoids vocalizes. In the anatomy of vocalization, I have recently asked about and explored some variation in vocal cords.
The hyoid bone typically ossifies in six places in humans; in lesser cats, studies have shown it is fully ossified and this may be what allows them to purr. What is observed in big cats shows that they do not have a fully ossified hyoid.
How would having a hyoid more like that of a big cat expand the humanoid's vocal range? Would this prevent them from using human languages understandably? Would they be able to roar?
