Method Details

dispose

protected void dispose(boolean disposing)

This method performs cleanup of resources. The Boolean parameter disposing indicates whether the method is called from Dispose (if disposing is true) or from the finalizer (if disposing is false). Derived classes should override this method to dispose resource if needed.

Overrides:

ConversationTranscriber.dispose(boolean disposing)

Parameters:

disposing

getAuthorizationToken

public String getAuthorizationToken()

Gets the authorization token used to communicate with the service.

Returns:

Authorization token.

getOutputFormat

public OutputFormat getOutputFormat()

Gets the output format of recognition.

Returns:

The output format of recognition.

getProperties

public PropertyCollection getProperties()

The collection of properties and their values defined for this ConversationTranscriber.

Returns:

The collection of properties and their values defined for this ConversationTranscriber.

getSpeechRecognitionLanguage

public String getSpeechRecognitionLanguage()

Gets the spoken language of recognition.

Returns:

The spoken language of recognition.

setAuthorizationToken

public void setAuthorizationToken(String token)

Sets the authorization token used to communicate with the service. Note: The caller needs to ensure that the authorization token is valid. Before the authorization token expires, the caller needs to refresh it by calling this setter with a new valid token. Otherwise, the recognizer will encounter errors during recognition.

Parameters:

token - Authorization token.

startTranscribingAsync

public Future startTranscribingAsync()

Starts conversation transcribing on a continuous audio stream, until stopTranscribingAsync() is called. User must subscribe to events to receive transcription results.

Returns:

A task representing the asynchronous operation that starts the transcription.

stopTranscribingAsync

public Future stopTranscribingAsync()

Stops conversation transcribing.

Returns:

A task representing the asynchronous operation that stops the transcription.
