The present invention (110) permits a user to speed up and slow down speech
without changing the speakers pitch (102, 110, 112, 128, 402-416). It is
a user adjustable feature to change the spoken rate to the listeners' preferred
listening rate or comfort. It can be included on the phone as a customer convenience
feature without changing any characteristics of the speakers voice besides the
speaking rate with soft key button (202) combinations (in interconnect or
normal). From the users perspective, it would seem only that the talker changed
his speaking rate, and not that the speech was digitally altered in any way. The
pitch and general prosody of the speaker are preserved. The following uses of the
time expansion/compression feature are listed to compliment already existing technologies
or applications in progress including messaging services, messaging applications
and games, real-time feature to slow down the listening rate.
