The Speaking of One's Own
message here is quite clear: a person's
hearing his own voice is a characteristic
of the End Times. For this to become a reality,
one's voice first has to be recorded. Such
recording and reproduction technology was
developed during the twentieth century.
This turning point in the advancement of
science enabled the birth of the communications
and media industries. Voice recording has
now reached its apogee via the latest developments
in computer and laser technology.
In short, such electronic devices as microphones
and speakers have made it possible to record
and listen to a person's voice, and thus
have fulfilled the above hadith.
