A voice processing system comprises a processing device that processes and
receives a stream of voice input as a user is speaking. A software
program executes program steps for determining a predetermined pattern of
speech and silence during processing of stream of voice input so as to
play or present the predetermined backchannel response to the user. A
method provides an audible backchannel response between the voice
processing system and the user, while the user is speaking, in
particular, recording a message. The method includes monitoring the
message to determine a predetermined pattern of speech and silence based
on timing between the speech and silence periods. Then, the method
produces the audible backchannel response based on the predetermined
pattern. An audible user interface includes a speech processor that
processes or classifies an audio message in the telecommunication device
as speech and silence frame while a calling party is speaking, in
particular, recording the audio message to a called party. A control
circuitry cooperates with the speech processor and responds to a
predetermined pattern of the speech and silence segments so as to play
the preset backchannel response in audible form to the calling party.
