ReadingBar Supported Control Codes

There are many possibilities that can be created using VXML Tags. Web Pages can be customized to control playback for a greatly improved experience. Simply add a tag in the appropriate location on your site, and ReadingBar will skip over the tag, performing the specified action.

Volume Control

Volume control allows for adjustments in the overall volume and scales from 0 - 200, with 0 being a whisper and 200 being very loud.

<volume level="50">
This text should be spoken at volume level fifty.
</volume>

<volume level="100">
This text should be spoken at volume level one hundred.
</volume>

<volume level="80" />
All text which follows should be spoken at volume level eighty.

Speed Control

Speed can be adjusted using two different methods. The first is absspeed. Absspeed is able to adjust the overall rate (speed), while the second method adjusts the rate in relation to the users preference. We recommend using the "Preferred Method."

<rate absspeed="5">
This text should be spoken at rate five.
</rate>

<rate absspeed="-5">
This text should be spoken at rate negative five.
</rate>

Speed Control **Preferred Method**

<rate speed="5">
This text should be spoken at rate five.
</rate>

<rate speed="-5">
This text should be spoken at rate zero.
</rate>

Spelling Control

To have ReadingBar read out each letter of a word or a portion of text use the following.

<spell>
These words should be spelled out.
</spell>

These words should not be spelled out.

Pronunciation Control

Use the following method to adjust pronunciation of words:

<pron sym="h eh l l ow & w er l l d"> hello world </pron>

Silence Control

In order to create an additional pause at the end of a sentence or at any point in playback and time of silence can be added. The time is measured in milliseconds and experimenting can yield almost any effect.

Five hundred milliseconds of silence <silence msec="500" /> just occurred.

Voice Control

Voices can be easily changed using the voice control tags. If the voice has not been loaded in the current session a noticeable pause will occur while it is loaded into memory. After the initial load each session voice switching can be done smoothly.
