Voice prompts?

Hi - I have used Alyson (Digium) for all of my IVR menu prompts but I see they put their prices up and reduced the number of words per prompt. Therefore, can anyone recommend any other good voice artists or companies that offer high quality recorded prompts? I see some of these virtual office sites offer 250 words for like $50 but you have to use it only on their services.

Thanks!

it’s so tempting to persuade my wife to do voice recordings. she’s not as perky as The Voice, but before we were married she was “forced” to record all the prompts where she worked.
