This list of phonemes are the only letter combinations the TTS engine will recognize.
Notice all vowel phonemes are immediately followed a number (0 or 1). These
numbers are emphasis values, where the 0 de-emphasizes that phoneme, and a 1 em
-
phasizes that phoneme. Every vowel phoneme must contain an emphasis value (0 or 1)
for the TTS engine to work properly.
Sample Text Section
Below the Lexicon Table is the Sample Text section. It is in the section where individual
words and sentences can be sampled by the TTS engine. This section also includes the
speed and pitch settings for this specific voice, along with saving/viewing the lexicon
table files.
1. To sample a word, sentence or paragraph, enter the text into the
Sample Text
field.
If this field is not large enough to accommodate the text in one view, click and drag
the bottom right corner of the field to make it the appropriate size.
2. Next, click the
Make TTS Sample
button. This action will create a sample of the text
you entered that can then be played within the web browser application.
3. To play the newly created sample, click the hyperlink
Listen to this sample of
Allison on the Browser
, and the web browser will play the latest TTS sample. The
date found to the left of the hyperlink represents the date and time of the last TTS
sample file that will be played.
4. After you have sampled the TTS file, click the
Back
button on the web browser to
return to the Edit Voice screen.
The speed of each Premium Voice can be adjusted by entering a new numeric value
into the
Words per minute
text field. The default value is 170. Lower numeric values
slow down the voice, and higher values increase its speed. The pitch of each voice can
be adjusted with the
Pitch factor percent
text field. The default value is 100 (or 100%).
The value can range from 50-150; any entered value that is above or below this range
will default to the nearest acceptable value. A lower value decreases the pitch, and a
higher value increases the pitch.
Attention
Make sure to click
the
Apply Changes
button after making
any changes to Word
Definitions, Words per
minute, and Pitch factor
values. This applies to
both the
Enable
check
box and
Delete
button
.
Note
The TTS engine is
not
case sensitive.
Word definition fields
will not allow upper
case letters, and will
properly pronounce
words that are received
with upper case letters,
such as proper names.
