<p>
If introduction is set, Tropo plays the TTS string using voice or plays the
audio file if a URL is defined (same behavior as say) during this wait.
Tropo will not return until introduction is done playing, even if it has
determined a human voice or machine response before the introduction is
complete.

<p>
For the most accurate results, the "introduction" should be long enough to
give Tropo time to detect a human or machine. The longer the introduction,
the more time we have to determine how the call was answered. If the
introduction is long enough to play until the voicemail "beep" plays, Tropo
will have the most accurate detection. It takes a minimum of four seconds
to determine if a call was answered by a human or machine, so introductions
four seconds or shorter will always return HUMAN.
