I have seen this thread but never really considered Jenna's voice until this week, mainly because I am sure it has been edited out. This explains why we have seen very little of her....the dreadful voice must be grating on everyone.
She sound like a 20-a-day high tar smoker, breathless with the addition of very shallow breathing, almost gasping for air in-between words. Throw in a childish, simpering tone and it's.....Jenna.
Another woman who sounds exactly like her is the dreadful winner of The Bachelor who became Gavin Henderson's girlfriend, Carine I think her name is? I couldn't stand her voice or her and only continued watching the program because it was such a high quality, thought provoking series.
Jenna needs to learn to breathe correctly and her voice will improve as will her chances of being taken seriously. But this advice is too late to help her voice being edited out of The Apprentice.
