Using The Speak Text Action; Tts Sapi Controls; Entering Xml Tags - Avaya IP Office Voicemail Pro Installation And Maintenance Manual

Using the Speak Text Action

One method of employing TTS is through adding a
spoken is entered in the action's Specific tab. This text can include combinations of:

Typed text sentences.

Voicemail Pro System Variables. For example:

Entering $KEY would be replaced when spoken by the last digits dialed within the call
flow by the caller.

If using database interaction, entering $DBD[x] would be replaced by the current value of
that database field.

Entering $CLI would speak the caller's CLI, if available, back to them.

SAPI 5 XML tags can be added to alter how the text is spoken. For example:

When 123 needs to be spoken as one two three rather than "one hundred and twenty-
three", enter <spell>123</spell>.

TTS SAPI Controls

Windows TTS engines use Microsoft's SAPI (Speech Application Program Interface). This includes the
use of XML tags in the text to change how the text is spoken. For example in the text This is the
<volume level="90">text</volume> to speak the items within < > brackets are XML tags used to
change how the speech is spoken.
The following are samples of the SAPI XML controls supported by Voicemail Pro TTS. Further
information on SAPI 5 can be obtained from Microsoft support websites.

Volume - Change the speech volume.

Rate - Change the speech rate.

Pitch - Change the speech pitch.

Emph - Add emphasis to words.

Spell - Spell out words and numbers literally.

Silence - Add a period of silence.

Partofsp - Change the usage of words.

Entering XML Tags

XML tags can be used in two ways, either nested or empty.

Nest Tags: Example = <volume level="90">text</volume>
Nested tags consist of

An opening XML tag, in the example above <volume level="90">

The text to which the opening tag command should be applied.

A closing XML tag. The closing tag use the same command as the opening tag, prefixed
with / and no other settings. In the example above this is </volume>.

Empty Tags: Example = <volume level="90"/>All following text
An empty tag is not nested, its command and settings apply to all the following text. Empty tags
are recognizable by the / before the tags closing >.
