[g-a-devel] gnome-speech driver parameters

[George Kraft <gk4 austin ibm com>]

The GNOME_Speech_Speaker.idl is able to set _voice_ parameters for
volume, rate, breathiness, roughness, pitch fluctuation, pitch, head
size, and gender.

I would like to propose GNOME_Speech_SynthesisDriver to be able to set
_driver_ parameters for dictionary, input type, language dialect, number
mode, sample rate, synthesis mode, text mode, want word indicies, and
want phoneme indices.

For example,

sp = GNOME_Speech_SynthesisDriver_createSpeaker(...);
GNOME_Speech_SynthesisDriver_setParameterValue(sp, InputType, Annotate);
speaker_say_print(sp, "\V0Hello World\V1Que Pasa");

Enclosed is an example enhanced IDL:

--- GNOME_Speech_SynthesisDriver.idl	2005-10-03 14:36:42.000000000 -0500

  	typedef sequence<VoiceInfo> VoiceInfoList;
    
  	interface SynthesisDriver : Bonobo::Unknown {

+ 		double getParameterValue (in string name);
+ 		boolean setParameterValue (in string name, in double value);
+ 
  	};
  };
  };
