Scratchy voice

I've been using a CPAP machine Philips Dreamstation (until the recall) and then Resmed AirSense 10. I've used humidity (hate the condensation) and not used humidity, but inevitably have a scratchy voice for most of the morning and sometimes all day. Any suggestions or insights would be greatly appreciated. BTW, I do sleep great and my throat does not feel dry when I wake up.

Many thanks in advance. I am a newbie so my apllogies if I have violated protocol.

Not sure how you think you could have violated some protocol (very few) but have you seen an ENT MD? Not everything's about Cpap (unfortunately .

Thanks! I have seen a couple. Everything checks out ok and they weren’t particularly helpful.
