Thanks, good to know. I was thinking a little more about the ending, it sounded a little cut off to me - more an 'uh' sound than an 'o' (English sounds) - if that makes sense? I wish I knew and could remember the IPA.
For me the ending is a very short o sound kind of like in pot, very different from the "oh" sound as in poke.
Thanks again! Your description is much better. It seems, therefore, that the TTS is accurate with this and I was hearing it correctly. That's good. I didn't want to attempt to perfect the sound if it might be inaccurate.
