Step-by-step instructions on how to create voice segments
are given later in this section, but there are different approaches
to this, so it is worthwhile taking some time to plan what you are
going to do:
- Decide whether to store voice segments in compressed format, uncompressed
format, or both.
- Decide on the source for your voice segments. You have the following
options:
- Record directly into Blueworx Voice Response using
the telephone.
- Record high-quality voice data, by one of the following methods:
- Recording directly into Blueworx Voice Response using
a microphone (needs audio capability on the planar of the Power System).
- Using a recording studio.
- If using a recording studio, decide how to transfer the voice
data into the Power System. You
can use either direct file transfer (recommended), digital audio tape
(DAT), or analog tape. Note that you may have to convert the format
of the voice data after transfer.
- If using a microphone directly or transferring voice data from
a recording studio, decide how to import segments into the Blueworx Voice Response voice
segment database. There are two methods:
- The Voice Segments window (select the voice segment in the Application
window and open it)
- The Batch Voice Import command-line process (a set of command
line utilities, with a control file).
Note that you can use both the voice segment editor and the Batch
Voice Import (BVI) utility to import voice data created on another
system. The voice segment editor supports only ‘raw’ unformatted
voice data files, the BVI utility supports Windows .wav files and
Apple Macintosh audio interchange file format (AIFF) files. Table 1 shows you which tool to use.

Notes:
- Although the voice segment editor can be used to import multiple
voice segments, depending on the number of voice segments, you might
find it quicker to use the BVI utility.
- The voice segment editor and the BVI utility both
require an integrated Micro Channel audio adapter to be present for
direct input of voice from microphone, tape recorder, or similar.
Note that if you don't have this audio capability on the planar of
your Power System,
there is currently no PCI plug-in audio board available.
If you
do not have audio capability on your computer, you can record voice
segments in one of the following ways:
- By using the telephone.
- By using another Power System with
audio support.
- By using a separate personal computer with an industry-standard
audio card (for example, Soundblaster) and import standard audio files
(such as .wav) using the Batch Voice Import facility.
- To import audio files from other computers, use either the TCP/IP
file transfer program (FTP) over a LAN or other network, or use a
removable storage device, such as a tape. You might find tape more
convenient to move bulk voice data to your Power System.
- For top-quality audio segments, we recommend that you record your
voice segments in a professional recording studio, then either import
a digital file (.wav or .aiff) or use digital audio tape.
