Member Function Documentation

virtual void BSAPI_METHOD SFeatureSegmenterI::SetFrameShiftMs

(

int

frameShiftMs = 10

)

[pure virtual]

Set frame shift.

Sets the frame shift in milliseconds. Frame shift is necessary to convert incoming segment times to feature frame indices.

Parameters:

frameShiftMs

frame shift in milliseconds

virtual void BSAPI_METHOD SFeatureSegmenterI::SetRepeatFrames

(

bool

repeatFrames = false

)

[pure virtual]

Enable frame repetition.

Controls the behaviour of segment extension. If the frame repetition is enabled, segments will be extended using the first and last frame. If the frame repetition is disabled, segments will be extended using out-of-segment (nonspeech) frames. If there is not enough frames to do so (at the beginning or end of the sentence) frame repetition is used no matter what is set by this function.

Parameters:

repeatFrames

enable or disable frame repetition

SetSegmentEndFrameExtension()

virtual void BSAPI_METHOD SFeatureSegmenterI::SetSegmentEndFrameExtension

(

int

segmentEndFrameExtension = 0

)

[pure virtual]

Set end segment extension in frames.

Sets the number of frames each segment will be extended from the end by

Parameters:

segmentEndFrameExtension

number of frames

virtual void BSAPI_METHOD SFeatureSegmenterI::SetSegmentStartFrameExtension

(

int

segmentStartFrameExtension = 0

)

[pure virtual]

Set start segment extension in frames.

Sets the number of frames each segment will be extended from the beginning by

Parameters:

segmentStartFrameExtension

number of frames

virtual void BSAPI_METHOD SFeatureSegmenterI::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 SFeatureSegmenterI::SetStartFrameOffset

(

int

startFrameOffset = 0

)

[pure virtual]

Set start offset in frames.

Allows to shift frames indexing to the right. It may be useful if there was some frame repetition done by the preceding block.

Parameters:

startFrameOffset

start offset in frames

virtual void BSAPI_METHOD SFeatureSegmenterI::SetTarget

(

SFeatureExtractionCallbackI *

pTarget

)

[pure virtual]

Set target object.

Target object receives segmented features.

Parameters:

pTarget

pointer to target object

virtual void BSAPI_METHOD SFeatureSegmenterI::SetWaitForWholeSentence

(

bool

waitForWholeSentence = false

)

[pure virtual]

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

Parameters:

waitForWholeSentence

enable or disable waiting for whole sentence
