video delivery speed

I have a hearing problem that manifests itself in speech that is delivered to quickly doesn't get processed. I am a veteran and have had hearing problems for 40 years. Youtube works because I can slow the delivery speed to 0.75 (usually where I set it) or even slower if the speaker has an accent that makes word distinction difficult for me. I have found no way to reduce the speed on any of the Onshape tutorial videos. Is there a way to do that which I have missed?
