@jesalrajdev: It appears to have already gone through!
First off, thank you so much for taking my suggestion and immediately implementing it. Best customer service I've received in months! Secondly, I notice that changing the playback speed to anything faster than 1.0x gives all the voices a grainy, robot-like tone. I notice that even YouTube sounds more metallic (sorry for my descriptions, best I can liken them to) when sped up past 1.0x, so this might just be an issue with the feature and not the app. If you want or are able to tweak it to sound clearer, that's up to you, but again, thank you for bothering to add the feature in the first place.
