April Meeting Notice

April 2005 Meeting Notice

Mei Wu will describe how speech intelligibility requirements are different for
teleconferencing than local conferences, how speech intelligibility can
be tested and predicted, how speech intelligibility is affected by the
sound system, signal to noise ratio and reverberation time, and how
these factors change during teleconferencing when speech is transmitted
to a remote location.  She will present a case study to show speech
intelligibility at various seats in a typical room, the change of speech
intelligibility due the change of talker's voice, microphone position
and acoustical treatment to the room.  She will also give a check list
for improving speech intelligibility in teleconference rooms.
