Standard English voice (Ivona) does not seem to be responding to new TTS requests

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use WebAnywhere with the Ivona voice. config.php should have the URL:
    http://webanywhere.cs.washington.edu/cgi-bin/ivona/getsound.pl?text=$text$&cache=1&mtts=1
2. Navigate to a page that does not have frequently requested text. (i.e. a 
random Wikipedia page)
3. New phrases that have not been cached will be skipped over without being 
converted to speech.

What is the expected output? What do you see instead?
All text requests should be converted to speech.

What version of the product are you using? On what operating system?
Trunk (Mar. 24, 2011)
OS X 10.6

Please provide any additional information below.
Switching to the standard espeak URL for the locale EN will temporarily work 
around the issue albeit in a different voice. Change the English config.php 
local entry to the following:

  $voices["en"] = 'http://webanywhere.cs.washington.edu/cgi-bin/espeak/getsound.pl?lang=en&text=$text$'; // English
