ConfigurationData(TUint32, TUint32, TUint32, TUint32)

HBufC8 *	ConfigurationData	(	TUint32	aPackageType,
			TUint32	aPackageID,
			TUint32	aStartPosition = 0,
			TUint32	aEndPosition = KMaxTUint32
		)	[pure virtual]

DevASR calls this method to get configuration data.

Since: 2.8

Parameters

TUint32 aPackageType
TUint32 aPackageID
TUint32 aStartPosition = 0
TUint32 aEndPosition = KMaxTUint32

DevASREvent(TDevASREvent, TDevASRError)

void	DevASREvent	(	TDevASREvent	aEvent,
			TDevASRError	aError
		)	[pure virtual]

DevASR notifies object implementing this interface whenever a spontaneous or non-spontaneous event occurs in DevASR.

Since: 2.8

Parameters

TDevASREvent aEvent
TDevASRError aError

DevASRMessage(TDesC8 &)

void

DevASRMessage

(

TDesC8 &

aMsg

)

[pure virtual]

DevASR calls this method to send a message in response to a custom command.

Since: 2.8

Parameters

TDesC8 & aMsg

FeatureVectorDataRcvd(const TDesC8 &, TInt32, TInt32)

void	FeatureVectorDataRcvd	(	const TDesC8 &	aFV,
			TInt32	aSNR,
			TInt32	aPosition
		)	[pure virtual]

DevASR notifies object implementing this interface when feature vectors are available.

Since: 2.8

Parameters

const TDesC8 & aFV
TInt32 aSNR
TInt32 aPosition

RequestSpeechData()

void

RequestSpeechData

(

)

[pure virtual]

Invoked by DevASR when it needs utterance data. The response is sent using SendSpeechData().

Since: 2.8

SILexiconL(TSILexiconID)

CSILexicon *

SILexiconL

(

TSILexiconID

aLexiconID

)

[pure virtual]

Called when DevASR needs a SI lexicon.

Since: 2.8

Parameters

TSILexiconID aLexiconID
