Is this really true in Modern Herew that there is a change in pronounciation of sounds for the sake of fast speech, if so, it's killing me! Even though the sentence didn't make sense to me, I thought I was clearly hearing "עוד" (more). I am ok with working on learning how vowels blend into each other as diphthongs, but to change a consonant with a "t" sound in to a "d" sound for the sake of pace, now that's painful to my soul. (sorry for the dramatic response here)
Thank you. English does something similar, I guess, when a written t gets pronounced more like a d. For example, I would pronounce "little bottle" more like "liddle boddle." But I wouldn't talk about "thad zebra." It's interesting how different languages have different natural sound morphing.
