Portable Voice Messaging System

      Disclosed is a portable device capable of checking phone
messages on a periodic basis, and of downloading such messages from a
remote telephone system.  This portable voice messaging system has a
speech-driven, hands-free interface, together with an ability to
forward and answer messages on other systems.

      Fig. 1 is an isometric view of a handheld version 1 of the
messaging system, which includes a four-position sliding switch
button 2 and a microphone 3.  Button 2 selects a Record/Action mode
in its first, or uppermost, position, a Stop/Interrupt mode in its
second position, a Play mode in its third position, and a Rewind mode
in its fourth, or lowermost, position.  The messaging system also
includes a microphone 3 and a speaker 4.

      Fig. 2 is a schematic diagram showing the major internal
components of the messaging system of Fig. 1.  An RJ11 jack 5 is used
to connect the messaging system to the standard wired telephone
network.  Alternatively, the messaging system may include cellular
receiving and transmitting capabilities, or the system may be
connected with a cellular network by attaching a cellular telephone
to RJ11 jack 5.  An internal audio storage unit 6 may be implemented
as solid state device, a miniature disk drive, or a miniature tape
drive.  The tape drive has an advantage of easily storing as much as
120 minutes of audio messages.  Data memory 7 includes non-volatile
storage of speech recognition application software, speech
compression software, and portable voice agent software.  The
messaging system additionally includes an Analog to Digital Converter
(ADC) 8, converting analog signals from microphone 3 and RJ-11 jack 5
into a digital form, a microprocessor 9, and a battery 10.  A power
jack 11 allows the system to be run with 12-volt current supplied
from an automobile battery, through a cigarette lighter connection,
or from a transformer connected to an external alternating current
source.  A Digital Signal Processor (DSP) 12 is optionally included.
The messaging system also includes Digital to Analog Convertor (DAC),
not shown, means for providing analog signals to RJ-11 jack 4 and
speaker 4.

      Providing output signals through the RJ-11 jack 4, the
messaging system periodically checks the telephone answering system
of the user, using the remote operating capability of the answering
system.  The portable voice agent mimics the push button tones of a
telephone to enter the telephone number, password, and other data if
required, eliminating a need to implement changes in the telephone
answering system.  The portable voice agent recognizes the various
me...
