This section describes how to set up the ZENO
®
-3200 and the speech and modem interface for robust
communications. This interface can also be used with a cellular modem; however, because of the noisy
and intermittent nature of cellular communications, some performance degradation of speech quality will
result, as well as limiting data rates on the data modem.

If you have purchased the ZENO
®
-3200 and
the speech interface as a part of a complete system, then everything is probably already configured for
your particular application. At most, you are likely only to create messages, or modify existing messages.
More details of the modem setup are given in Section 6.4 covering modem communications. This section
concentrates on speech.
6.11.1. Overview
The ZENO
®
-3200 Speech Interface allows for a single spoken message to be delivered via a standard
telephone connection. You can only program one message.
Ordinary text such as “the air temperature is…” will be converted to speech
using American English pronunciation rules.
146
A caller will be prompted to press a touch-tone key. If a tone is detected within about 5 seconds of the
prompt, the caller will hear a spoken message. If no tone is detected within this time, the ZENO
®
-3200
will begin handshaking to set up a modem (data) connection. So, a single phone line and a single serial
port on the ZENO
®
-3200 can be used for both voice and data communications (e.g., to download logged
data, or to reconfigure the ZENO
®
-3200).
The spoken message will normally contain a combination of fixed strings (such as “the air temperature
is…”) and data fields (such as “seventy-two”).
The following sections describe how to set up such a message.
6.11.2. Creating A Spoken Output Message
Creating a spoken output message within the ZENO
®
-3200 is very similar to creating any other output
message. Coastal Environmental Systems recommends that you read Section 10.6 before attempting to
configure a spoken message. This section only describes those aspects of the configuration that are
specific to the speech interface.
To designate which communications port is to be used for the spoken message, enter the Output Message
Timing Menu. The Output Message Timing Menu is accessible from the Zeno Program Menu by typing
the command O{ENTER}.

On occasion, it is necessary to change the spelling to accomplish a more understandable pronunciation, but this is
rare.

Refer to Section 10.7.
