Does the singin gibbon study inform debates on sasquatch vocalisation?

Has anyone seen the above. Google 'singing Gibbon study' and see what you think. I know there are some debates around bigfoot language and vocalisation so do people think this is evidence in support or Not? Presuppositions bigfoot exists of course. I would have pasted a link but I don't know how to do it on my mobile.. It's on BBC and reuters etc.

Other that the propensity of primates to vocalize in general, I don't see much of a relation other than supporting that statement.

Primates Vocalize

Language is altogether different, a key ingredient for culture, progressive intelligence.

I view Sasquatches as far beyond these creatures as we are, just in a different capacity.
