Method Details

addTargetLanguage

public void addTargetLanguage(String value)

Adds a target language for translation. Added in version 1.7.0.

Parameters:

value - the language identifier in BCP-47 format.

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:

TranslationRecognizer.dispose(boolean disposing)

Parameters:

disposing

getAuthorizationToken

public String getAuthorizationToken()

Gets the authorization token used to communicate with the service.

Returns:

Authorization token.

getProperties

public PropertyCollection getProperties()

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

Returns:

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

getSpeechRecognitionLanguage

public String getSpeechRecognitionLanguage()

Gets the spoken language of recognition.

Returns:

The spoken language of recognition.

getTargetLanguages

public ArrayList getTargetLanguages()

Gets all target languages that have been configured for translation.

Returns:

the list of target languages.

getVoiceName

public String getVoiceName()

Gets the name of output voice.

Returns:

the name of output voice.

recognizeOnceAsync

public Future recognizeOnceAsync()

Starts recognition and translation, and stops after the first utterance is recognized. The task returns the translation text as result. Note: RecognizeOnceAsync() returns when the first utterance has been recognized, so it is suitableonly for single shot recognition like command or query. For long-running recognition, use StartContinuousRecognitionAsync() instead.

Returns:

A task representing the recognition operation. The task returns a value of TranslationRecognitionResult.

removeTargetLanguage

public void removeTargetLanguage(String value)

Removes a target language for translation. Added in version 1.7.0.

Parameters:

value - the language identifier in BCP-47 format.

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.

startContinuousRecognitionAsync

public Future startContinuousRecognitionAsync()

Starts recognition and translation on a continuous audio stream, until StopContinuousRecognitionAsync() is called. User must subscribe to events to receive translation results.

Returns:

A task representing the asynchronous operation that starts the recognition.

stopContinuousRecognitionAsync

public Future stopContinuousRecognitionAsync()

Stops a running recognition operation as soon as possible and immediately requests a result based on the the input that has been processed so far. This works for all recognition operations, not just continuous ones, and facilitates the use of push-to-talk or "finish now" buttons for manual audio endpointing.

Returns:

A future that will complete when input processing has been stopped. Result generation, if applicable for the input provided, may happen after this task completes and should be handled with the appropriate event.
