Blankpaige wrote an interesting piece about some radio presenters whose voices she liked and disliked.
I've tried to think of 10 male and 10 female voices that I've liked listening to over the years. Note that I'm purely judging the sound of the voice, I'm not necessarily a fan of the person. They are also not in any particular order of favourites, nor have I put long thought into this (I'll probably think of others afterwards or regret some of the ones I've chosen!).
1. Vincent Price - I loved his unique clear, haunting, slightly aristocratic mellow tones.
2. Anthony Hopkins - great clear distinct poetic voice. "I ate his liver with some fava beans and a nice Chianti...fffhhh fffhhh fffhh".
3. Richard Burton - similar reasons as for Hopkins. They are both Welsh of course.
4. Gay Byrne - great intonation and expression, impossible to lose interest in what he is saying.
5. Ian Paisley - a passionate and decisive voice. I love mimicking him (I'm told I do it well!).
6. John F. Kennedy - nice positive delivery, smooth and easy to listen to Boston accent.
7. Ronald Reagan - could inspire and move in his speeches with his soft yet passionate voice
8. John Cleese - great stiff upper lip voice with so many interesting characteristics.
9. Pat Kenny - probably has the clearest diction and best delivery of all Irish broadcasters
10. Terry Wogan - distinctive, laid-back and easy to listen to.
1. Hilary Clinton - clear and positive.
2. Mary Robinson - throaty and deep, but pleasant and distinctive.
3. Meryl Streep - soft and wide ranging in expression.
4. Julia Roberts - good clear and pleasant American accent.
5. Audrey Hepburn - sophisticated, friendly, fragile, nice mixture of English/Continental tones.
6. Barbara Stanwick - a bassy voice with good delivery.
8. Jodie Foster - slightly nasal, distinctive and easy to listen to.
9. Grace Kelly - soft and regal.
10. Jennifer Lopez - quite smooth and warm NY accent.
If I was to pick a voice I've personally loved more than any other...it would be that of my spouse. She has a nice soft blend of her parents Derry/Donegal accents peppered with south east Dublin tones. But I'm biased!
