Run
http://translate.google.com/translate_tts?tl=en&q=hello in both firefox and chrome and you will see the problem.
HTML Code:
<embed type="audio/mpeg" src="http://translate.google.com/translate_tts?tl=en&q=hello" autostart="True"></embed>
This works in Firefox but not Chrome.
Is my only true alternative to run the audio through a flash file?
