Interface WaveformSynthesizer

All Known Implementing Classes:

HMMSynthesizer, InterpolatingSynthesizer, UnitSelectionSynthesizer

public interface WaveformSynthesizer

Provide a common interface for all waveform synthesizers, to be called from within the "wrapping" Synthesis module.

Method Summary

Modifier and Type	Method and Description
void	powerOnSelfTest() Perform a power-on self test by processing some example input data.
void	startup() Start up the waveform synthesizer.
AudioInputStream	synthesize(List<Element> tokensAndBoundaries, Voice voice, String outputParams) Synthesize a given part of a MaryXML document.

Method Detail

startup

void startup()
      throws Exception

Start up the waveform synthesizer. This must be called once before calling synthesize().

Throws:

Exception - Exception

powerOnSelfTest

void powerOnSelfTest()
              throws Error

Perform a power-on self test by processing some example input data.

Throws:

Error - if the module does not work properly.

synthesize

AudioInputStream synthesize(List<Element> tokensAndBoundaries,
                            Voice voice,
                            String outputParams)
                     throws SynthesisException

Synthesize a given part of a MaryXML document. This method is expected to be thread-safe.

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.
