Answer: homo sapiens is the only species with a large enough oral cavity and a low enough larynx to allow for speech production.

One line of evidence that speech only possible for modern homo sapiens is the anatomy of their throat. Speech depends on certain anatomical arrangements and the Homo sapiens is the only species with a large enough oral cavity and a low enough larynx that would allow speech.
