Chapter 10. Visual and Audio Analysis

The use of sound, images, and videos is becoming a more important aspect of our day-to-day lives. Phone conversations and devices reliant on voice commands are increasingly common. People regularly conduct video chats with other people around the world. There has been a rapid proliferation of photo and video sharing sites. Applications that utilize images, video, and sound from a variety of sources are becoming more common.

In this chapter, we will demonstrate several techniques available to Java to process sounds and images. The first part of the chapter addresses sound processing. Both speech recognition and Text-To-Speech (TTS) APIs will be demonstrated. Specifically, we will use the FreeTTS (http://freetts.sourceforge.net/docs/index.php) API to convert text to speech, followed with a demonstration of the CMU Sphinx toolkit for speech recognition.

The Java Speech API (JSAPI) (http://www.oracle.com/technetwork/java/index-140170.html) provides...
