virtual void BSAPI_METHOD SWaveformSegmenterI::SetMinimumSegmentLength

(

int

minSegmentLengthMs = 0

)

[pure virtual]

Set if produced segments are to small (decoder crashes on 2 frame segments)

Parameters:

minSegmentLengthMs

set minimal length of wave segment in ms. Smaller segment is then enlarged by SetSegmentStartExtensionMs() SetSegmentEndExtensionMs()

virtual void BSAPI_METHOD SWaveformSegmenterI::SetSegmentEndExtensionMs

(

int

segmentEndExtensionMs = 0

)

[pure virtual]

Set end segment extension in milliseconds.

Sets the portion of waveform in milliseconds each segment will be extended from the end by

Parameters:

segmentEndExtensionMs

extension length in milliseconds

virtual void BSAPI_METHOD SWaveformSegmenterI::SetSegmentStartExtensionMs

(

int

segmentStartExtensionMs = 0

)

[pure virtual]

Set start segment extension in milliseconds.

Sets the portion of waveform in milliseconds each segment will be extended from the beginning by

Parameters:

segmentStartExtensionMs

extension length in milliseconds

virtual void BSAPI_METHOD SWaveformSegmenterI::SetSpeechLabel

(

const char *

pSpeechLabel = "voice"

)

[pure virtual]

Set speech label to be used with segmentation.

Sets the label value so the segments with this label coming to the OnTranscription callback will be considered as speech and will be processed

Parameters:

pSpeechLabel

label of (speech) segments to be processed

virtual void BSAPI_METHOD SWaveformSegmenterI::SetTarget

(

SWaveformSourceCallbackI *

pTarget

)

[pure virtual]

Set target object.

Target object receives segmented waveform.

Parameters:

pTarget

pointer to target object

virtual void BSAPI_METHOD SWaveformSegmenterI::SetUseNeighbouringWaveform

(

bool

useNeighbouringWaveform = true

)

[pure virtual]

Enable neighbouring waveform to be used by segment extension.

Controls the behaviour of segment extension. If the usage of neighbouring waveform is disabled segments are going to be extended from the beginning/end by samples whose value is an average of first/last few samples. If the usage of neighbouring waveform is enabled, segments will be extended using out-of-segment (nonspeech) waveform. If there is not enough samples to do so (at the beginning or end of the sentence) extension by an average sample is used no matter what is set by this function.

Parameters:

useNeighbouringWaveform

enable or disable usage of neighbouring waveform

SetSegmentEndExtensionMs()

virtual void BSAPI_METHOD SWaveformSegmenterI::SetWaitForWholeSentence

(

bool

waitForWholeSentence = false

)

[pure virtual]

Set whether to wait for all the segments before sending segmented waveform.

Parameters:

waitForWholeSentence

enable or disable waiting for whole sentence
