Applications that generate JSML text should respect the default settings of the user. To do this, relative settings of parameters such as pitch and speaking rate should be used rather than absolute settings.
The object can also be used in the selection of a speech synthesizer. The following code illustrates how to create a synthesizer with a young female Japanese voice.
