How to implement
TrueSpeech

Step 1: Create
a WAV file.

If you already have a wav file that you wish to use, skip to
step 2.

Create PCM-encoded WAV files at an 8KHz sampling rate with
16-bit resolution, mono.

Any multimedia board which is SoundBlaster(tm) 16 compatible
will support this format. To achieve the best quality, record
with these settings. If your audio equipment does not support
this format, use a conversion utilities such as Cool Edit or
SoundForge for converting to the necessary format.

Step 2: Convert
to TrueSpeech.

To convert PCM-encoded WAV files to TrueSpeech WAV files, use
the Microsoft Sound System in Windows 95 or NT.

In Sound Recorder:

1. Select Open from the File menu. Select the desired WAV
file, and click OK.

2. Select Save As from the File menu.

3. Click Change to display the Sound Selection dialog box.

4. Select DSP Group TrueSpeech(TM) from the Format list box, and
click OK.

5. Specify a new Filename, if desired, and click OK.

The new file is encoded in the TrueSpeech format with a
compression rate of 15x.

For those who are using Windows 3.11 or a Macintosh, a href="http://www.dspg.com/player/dwnld.htm">TrueSpeech conversion
utility may be downloaded from this site. This conversion
utility will accept PCM-encoded WAV files only if sampled at
8KHz/16-bit PCM format.

Step 3: Create
a Text File.

Use a standard text editor such as Notepad and give this file
a TSP extension. This is done so the browser launches the
TrueSpeech Player when a TrueSpeech-encoded WAV file is about to
be transmitted. The TSP file associated with a TrueSpeech-encoded
WAV file should contain the following (case-sensitive) HTML line:

TSIP>>URL/*.wav

The URL above should not include the "http://"
characters. For example, www.dspg.com would be appropriate and
http://www.dspg.com would not.

Let's suppose you create a PCM-encoded WAV file and convert it
to TrueSpeech. Give this file the name test.wav. Next, suppose
that this file is located at your server in the directory
www.home.com/audio. It is now necessary to create a one line .tsp
text file. This file should contain the following line:

TSIP>>www.home.com/audio/test.wav

You can simply name this file test.tsp

Step 4: Link.

Link the *.tsp text file to any image or text you specify on
your page. When a visitor clicks on this link, the TrueSpeech
Player starts. Upon spawning the player, the TrueSpeech Player
reads the location of the TrueSpeech *.wav file from the *.tsp
file. The Player then accesses and plays the file as it is being
downloaded, in real time.

To Listen to TrueSpeech files you can download the player from
the TrueSpeech
home page.
