      ICSLP unites researchers, developers, and clinicians for an 
exchange
      on a wide variety of topics related to spoken language processing 
by
      humans and machines. Conference presentations range from basic
      acoustic phonetic research to clinically oriented speech training
      devices to speech-based natural language interfaces for man-
machine
      interaction. ICSLP 96 will feature technical sessions in both oral
      and poster format, plenary talks, commercial exhibits, and daily
      special sessions. In addition, satellite workshops will be held in
      conjunction with the conference in the areas of interactive voice
      technology, spoken dialogue, speech databases and speech I/O, and
      the integration of gestures and speech.  A new emphasis for ICSLP 
96
      will be on the clinical applications of speech technology, 
including
      the use of speech technology based applications for persons with
      disabilities.

      integration of gesture and spoken language in intelligent
      human/computer interfaces, advanced assistive technology for
      individuals with disabilities, telemanipulation and robotics 
systems,
      and human conversation. Gestures including hand postures, dynamic

I would like to use the Internet to bridge two hybrid PBX systems. The
PBX's have two wire E&M capability, but a real tie line would cost a


                                                                           

fortune.  I was thinking that if I could convert the E & M circuit to
Async RS-232 I could write an application to do a full-duplex ftp
operation (on demand if possible).

Does anyone know of such a converter or perhaps a more suitable 
solution?

You need to isolate the 48 volt battery on the phone line from what
ever you are using as an audio source.  You also need to balance the
line from ground as your tape deck/ stereo might have a ground on the
jack -- if it is plugged in.

I'd recommend that you get a small transformer from someplace like
Radio Shack.  They used to cost a couple bucks.  Look at the winding
impedances.  You should see something between 200 and 2000 ohms for
one side and something between 3.2 ohms and 1000 ohms on the other
side.  You'll also need a 2 to 5 microfarad  (uF) capacitor that is
NON-ELECTROLYTIC.  

The lower impedance side of the transformer goes into your radio,
cassette, etc.  The higher impedance side goes to the phone line with
the capacitor in series with one of the leads.

This arrangement will NOT hold the phone line, so you will have to
stay off hook while you are playing your tape.  If you want it to hold
the line you'll need a 200 to 800 ohm resistor across the phone line.
Use the biggest value that will hold the line.

You could get fancier, but that'll do it without damaging either the
phone line or your audio sources.

You might try tracking down a "music-oh-hold" device, if such a beast
exists.  Please be aware that FCC and Industry Canada rules prohibit
the sale of devices that don't limit the energy sent out over the
telephone line.  As such, the line-level audio from your RCA output
can't be legally connected to the phone line without something to
limit its output power.  This said, it is certainly possible to
"illegally" connect your RCA jack to a telephone connection.  

I believe some of the devices used to *record* telephone conversations
(sold in the "back" sections of many electronics magazines) could be
pressed into service to provide this function.  You might consider
using this setup with a telephone having mute capability to prevent
your telephone from adding unwanted signals and distortion to your
RCA-jack audio signal.  An isolation transformer capable of carrying
the telephone line's DC current is also recommended.  I can provide
information on such transformers if you like.

Coincidentally, I am in the process of helping develop a product that
allows (among other things) the playback of sound card audio out to
the telephone line.  This device *has* been approved in accordance
with FCC rules (soon Industry Canada) and we hope to have it available
early in 1996.  Send me a private e-mail for more information.

Just a thought ...

Some phones give a short burst of tone, others send it for as long as
the button is pressed. I've had this problem interogating my answering
machine. If your phone is the former, perhaps the tone burst is too
short (or too quiet).

Hey, at least you got a letter -- a few years ago my SPRINT calling
card stopped working.  Fortunately I had a business calling card, so I
was able to make my calls on that trip.  When I got home I called
SPRINT; they said that my card had shown calls "outside my normal
pattern" and that they had thus cancelled the card.  In fact, the call
in question was from NYC to my parents, in Canada.  When I pointed out
that I call that number regularly, and that the odds of someone
stealing my card so they could call my parents were, shall we say,
low, they said "We don't have access to that kind of information" (so
how do they determine what a "normal" pattern is?).

The bottom line seemed to be that I had used the calling card from --
gasp! -- somewhere I don't live (what a concept), so they cancelled
it.  I asked why they hadn't notified me; they said "We always try to
call".  I pointed out that I got no message on my answering machine,
and they said they don't leave messages on answering machines!  Must
be too high-tech for them.

I suggested they send me 50 calling cards, so I could use each one
once, and then they would presumably cancel it; they didn't like that
much, but did send me a new card.  And actually haven't cancelled it.
Perhaps there's a red flag on the account ...
