Class FrameDecoder

java.lang.Object

edu.cmu.sphinx.decoder.AbstractDecoder

edu.cmu.sphinx.decoder.FrameDecoder

All Implemented Interfaces:

ResultProducer, DataProcessor, Configurable

public class FrameDecoder
extends AbstractDecoder
implements DataProcessor

A decoder which does not use the common pull-principle of S4 but processes only one single frame on each call of decode(). When using this decoder, make sure that the AcousticScorer used by the SearchManager can access some buffered Datas.

FrameDecoder

public FrameDecoder()

Method Detail

decode

public Result decode(java.lang.String referenceText)

Decode a single frame.

Specified by:

decode in class AbstractDecoder

Parameters:

referenceText - the reference text (or null)

Returns:

a result

getData

public Data getData()
             throws DataProcessingException

Description copied from interface: DataProcessor

Returns the processed Data output.

Specified by:

getData in interface DataProcessor

Returns:

an Data object that has been processed by this DataProcessor

Throws:

DataProcessingException - if a data processor error occurs

getPredecessor

public DataProcessor getPredecessor()

Description copied from interface: DataProcessor

Returns the predecessor DataProcessor.

Specified by:

getPredecessor in interface DataProcessor

Returns:

the predecessor

setPredecessor

public void setPredecessor(DataProcessor predecessor)

Description copied from interface: DataProcessor

Sets the predecessor DataProcessor. This method allows dynamic reconfiguration of the front end.

Specified by:

setPredecessor in interface DataProcessor

Parameters:

predecessor - the new predecessor of this DataProcessor

initialize

public void initialize()

Description copied from interface: DataProcessor

Initializes this DataProcessor. This is typically called after the DataProcessor has been configured.

Specified by:

initialize in interface DataProcessor
