The Speech plugin

Available since version: 0.10.0
Author: Tobias Bräutigam

Description

Use the Web Speech API (https://developer.mozilla.org/en-US/docs/Web/API/Web_Speech_API) to make text-to-speech service available. This plugin listens to a address and forwards the incoming data to the browser TTS engine (if the browser supports it)

Simple example

<speech lang="en">
 <address transform="OH:string" mode="read">Speak</address>
</speech>

Example preventing repetition within a timeout and use mapping

...
<meta>
 <plugins>
   <plugin name="speech" />
 </plugins>
 <mappings>
   <mapping name="speak">
     <entry value="0">Hello, welcome home</entry>
     <entry value="1">Please close all windows</entry>
     <entry value="2">Please close all doors</entry>
   </mapping>
 </mappings>
</meta>
...
<speech lang="en" repeat-timout="300" mapping="speak">
 <address transform="DPT:5.010" mode="read">Speak</address>
</speech>

Settings

For a general understanding of how the configuration files are structured and what elements and attributes are it is recommended to read this section first: Pages and structure of CometVisu.

The behaviour and appearance of the speech plugins can be influenced by using certain attributes and elements. The following tables show the allowed attributes and elements and their possible values. The screenshots show, how both can be edited in the editor.

Attributes underlined by ..... are mandatory, all the others are optional and be omitted.

Allowed attributes in the speech-element
