Method Details

additionalUsageInfo

protected List<org.apache.commons.cli.Option> additionalUsageInfo()

Description copied from class: DiarcComponent

Override this method to define command line options available in sub-class. This should be paired with a parseArgs implementation.

Overrides:

additionalUsageInfo in class DiarcComponent

Returns:

parseArgs

protected void parseArgs(org.apache.commons.cli.CommandLine cmdLine)

Description copied from class: DiarcComponent

Override this method to parse command line args in the sub-class. Called directly after construction to pass runtime values that will override default values. This should parse all the options that additionalUsageInfo provides.

Overrides:

parseArgs in class DiarcComponent

init

protected void init()

Description copied from class: DiarcComponent

Perform any component initialization. This should not be used for setting local fields to default values as was the case in DIARC. This method is called after the constructor, and after parseArgs. Setting default values should be done in field declaration or in the constructor.

Overrides:

init in class DiarcComponent

shutdownComponent

public void shutdownComponent()

Description copied from class: DiarcComponent

Any component that needs particular shutdown logic needs to override this method and

Overrides:

shutdownComponent in class DiarcComponent

transcribeSpeech

public String transcribeSpeech(float[] samples)

Transcribe audio data in 16kHz, mono F32

Specified by:

transcribeSpeech in interface ASRInterface

Parameters:

samples - Audio.java data

Returns:

transcribed text

transcribeAndReportSpeech

public void transcribeAndReportSpeech(float[] samples)

Transcribe audio in 16kHz, mono F32 and report to listener component.

Specified by:

transcribeAndReportSpeech in interface ASRInterface

Parameters:

samples - Audio.java data

writeFloatArrayToWav

public void writeFloatArrayToWav(float[] audioData,
 String filePath,
 int sampleRate)

Create a wav file from audio sample data.

Parameters:

audioData - audio data in floating point representation

filePath - file to save audio to

sampleRate - sample rate of the audio

disableMicrophone

public void disableMicrophone()

Specified by:

disableMicrophone in interface ASRInterface

enableMicrophone

public void enableMicrophone()

Specified by:

enableMicrophone in interface ASRInterface
