Specified by:

synthesize in interface WaveformSynthesizer

Parameters:

tokensAndBoundaries - the part of the MaryXML document to synthesize; a list containing a number of adjacent t and boundary elements.

voice - the Voice to use for synthesis

outputParams - any specified output parameters; may be null

Returns:

an AudioInputStream in synthesizer-native audio format.

Throws:

SynthesisException - if the voice requested for this section is incompatible with this WaveformSynthesizer.
