  com.sun.speech.freetts.jsapi.FreeTTSEngineCentral

All Implemented Interfaces:

javax.speech.EngineCentral

public class FreeTTSEngineCentral

extends java.lang.Object

implements javax.speech.EngineCentral

Supports the EngineCentral JSAPI 1.0 interface for the FreeTTSSynthesizer. To use a FreeTTSSynthesizer, you should place a line into the speech.properties file as so:

 FreeTTSSynthEngineCentral=com.sun.speech.freetts.jsapi.FreeTTSEngineCentral

Creates a FreeTTSEngineCentral

Method Detail

createEngineList

public javax.speech.EngineList createEngineList(javax.speech.EngineModeDesc require)

Returns a list containing references to all matching synthesizers. The mapping of FreeTTS VoiceDirectories and Voices to JSAPI Synthesizers and Voices is as follows:

• Each FreeTTS VoiceDirectory specifies the list of FreeTTS Voices supported by that directory. Each Voice in that directory specifies its name (e.g., "kevin" "kevin16" "alan"), domain (e.g., "general" or "time") and locale (e.g., Locale.US).
• For all FreeTTS Voices from all VoiceDirectories discovered by the VoiceManager, this method will group the Voices according to those that have both a common locale and domain (e.g, all "general" domain voices for the US local will be grouped together).
• For each group of voices that shares a common locale and domain, this method generates a new JSAPI SynthesizerModeDesc with the following attributes:
  • The engine name is of the form: "FreeTTS <locale> <domain> synthesizer" For example, "FreeTTS en_us general synthesizer"
  • The locale is the locale shared by all the voices (e.g., Locale.US)
  • The mode name is the domain shared by all the voices (e.g., "general").
• The JSAPI Voices for each resulting Synthesizer will have the name of the FreeTTS Voice (e.g. "kevin" "kevin16").

Specified by:

createEngineList in interface javax.speech.EngineCentral

Parameters:

require - an engine mode that describes the desired synthesizer

Returns:

an engineList containing matching engines, or null if no matching engines are found
