He, or she, might take exception to the term "boys voice"
13200 kHz is one of the US Air Force HF-GCS frequencies (any military branch can use it, but it is an USAF system). The format you describe is roughly correct for an HF-GCS message. So most likely what you heard was, indeed, an HF-GCS message, possibly what is called by hobbiest an "EAM", or Emergency Action Message (not all coded messages on the HF-GCS system are EAMs, but people tend to lump them all together). And if this is what you heard the voice was that of an active duty US military member, probably US Air Force.
Other frequencies to watch for this type of activity are 4724, 6739, 8992, 11175, and 15016 kHz, in addition to the 13200 kHz you noted. Most often all frequencies will be transmitting the same message at the same time, and you can generally find one with good propagation to you. That is why the system is designed like it is, GCS stands for Global Communications System, and I don't think I have ever been someplace that I could not receive these messages.
