<p>This sample demonstrates how to create a text to speech engine
that users can install on their devices.</p>
<p>The application includes a service and two activities:</p>
<ul>
<li><a
href="src/com/example/android/ttsengine/RobotSpeakTtsService.html"><code>RobotSpeakTtsService</code></a>,
a simple text to speech engine that converts sentences into audio by
generating a square wave of a given frequency for each alphabet of a
given language. Though this doesn't qualify as speech (except for robots)
it exercises all aspects of the new text to speech API
by subclassing the
<a href="../../../reference/android/speech/tts/TextToSpeechService.html"><code>TextToSpeechService</code></a>
framework class.
</li>
<li><a
href="src/com/example/android/ttsengine/CheckVoiceData.html"><code>CheckVoiceData</code></a>,
an activity that checks that all voice related data is installed and
available.</li>
<li><a
href="src/com/example/android/ttsengine/RobotSpeakSettings.html"><code>RobotSpeakSettings</code></a>,
a settings screen for users to set various engine parameters. This is
usually accessed by users from the system wide settings app. This must be
declared in the <code>AndroidManifest.xml</code> file as a
<code>meta-data</code> element.</li>
<!-- TODO: Fix this when the API level for ICS is finalized -->
<p>Note that this API is supported only on Android 4.0 (API level 13)
and higher versions of the platform.</p>
