The program can play both pre-prepared sound files (*.WAV)
and text files (*.TXT or *.MIX), via the modem in the telephone
line or the computer's sound device. In the latter case
what is known as 'text-to-speech' (TTS) translation takes
place. The translation is performed by a TTS engine that
must be installed independently of the program. After the
engine is installed, one or more TTS Voices appear in the
system, as 'Microsoft Sam' for example. Venta4Net supports
SAPI version 4 and 5.1 engines. The standard Windows XP
package includes the SAPI version 5.1 engine (English language
only). Version 4 engines can be downloaded from the Microsoft
web site:
SAPI 4 programming interface: http://www.microsoft.com/msagent/downloads/user.asp#sapi
Various engines: http://www.microsoft.com/msagent/downloads/user.asp#tts
Other companies also provide TTS engines.
Enabling the TTS mode
Open the Text-To-Speech Translation (TTS) - General
tab. If speech engines (voices) have been installed in the
system, they will appear in the Voice selection drop-down
list. Select the voice you wish to use.
Playing back caller information
After a caller's phone number is delivered (by means of
Caller ID), it can be played back via the computer's sound
device. The Voicing number via sound device setting
under the Caller ID - Displaying and Voicing tab
must be enabled for this purpose. When using TTS, certain
other information about the caller (in addition to his or
her phone number) can also be reproduced. The program searches
for the delivered phone number in all available phonebooks.
If the search is successful, the caller's name and/or the
contents of the phonebook's Comment field can be
played back.
In order to use TTS for playing back caller information,
check the Use for voicing caller information box
under the Text-To-Speech Translation (TTS) - General
tab. By default, the caller's delivered phone number and
name - if the number is found in one of the phonebooks -
are reproduced. The information to be played back can be
customized. To do so, open the Text-To-Speech Translation
(TTS) - Advanced tab. The Caller information
field can contain variables that specify what exactly will
be played.
Before the phone number is given, the text from the Number
field is played back. In the event the caller's number is
not delivered, the text from the Not-delivered field
is played back.
Using TTS for voicing via modem
With TTS, all announcements to be played back in the telephone
line, such as the answering machine greeting message, can
be specified by text files (*.TXT). Check the Use for
voicing via modem setting under the Text-To-Speech
Translation (TTS) - General tab. To select a text announcement,
open the Folders and Files - Service Files tab, and
select the desired announcement files. Selected announcements
can be played back and edited, if necessary, in the same
tab.
In addition, a text file can be transmitted as a voice message,
including a scheduled delivery option. To prevent the text
file from being converted to facsimile format, enable the
Send text files (*.txt) as voice messages setting
under the Text-To-Speech Translation (TTS) - General
tab.
Special text files (*.MIX)
Files with an *.MIX extension are treated differently by
the program. These files may contain both text lines and
links to both text (*.TXT) and sound (*.WAV) files. Text
lines must be placed in double quotation marks (e.g., "text
line"). If file names do not contain the full path,
it is assumed they are located in the same folder as the
*.MIX file. Text lines can also contain variables. This
version of Venta4Net does not support TTS text file playback
in the remote control scripts.
Playing back answering machine remote control
phrases
You can also redefine some phrases used in an answering
machine remote control session, under the Text-To-Speech
Translation (TTS) - Advanced tab. These phrases are
used when the PLAY_REP_INFO X operation is performed.
In addition, the Extended information setting can
contain several variables that specify which data are to
be played back for various answering machine playback operations
if the settings of these operations [PA] are not set to
zero.
