SpeechObjectsThe Foundation SpeechObjects, Nuance’s Java-based speech applicationdevelopment framework, defines classes that let you create specific TTS promptobjects from a simple text string. This class, TTSPrompt, implements the Playableinterface, which allows it to be appended to a prompt queue and playeddirectly:vcommerce.util.prompt.Playablevoid appendTo(PromptPlayer player)NuanceSpeechChannelTTSPromptjava.lang.String getText()void setText (java.lang.String text)To use the TTSPrompt class, just set the text string you want to be synthesized.You can then append the prompt to the prompt queue of yourSpeechChannel. For example:TTSPrompt tts = new TTSPrompt("Hello world");tts.appendTo(sc);Note: In this example, sc is the SpeechChannel object being used by yourapplication.If you are programming with the NuanceSpeechChannel API directly instead ofusing the Foundation SpeechObjects, use the appendTTS method defined in theCorePromptPlayer interface to create TTS prompts. This method creates theprompt and appends it to the prompt queue.The NuanceSpeechChannel class includes a default implementation of theCorePromptPlayer interface. For example, if sc is your NuanceSpeechChannelobject, the following appends and plays a TTS prompt:CorePromptPlayer player = sc.getPromptPlayer();player.appendTTS("Hello world");player.play(false);For more information about the NuanceSpeechChannel API, see the onlinedocumentation shipped with the Nuance System.28Nuance Vocalizer 3.0Developer’s Guide
