Inheritance
TranslationRecognizer

Constructor

TranslationRecognizer(translation_config: SpeechTranslationConfig, auto_detect_source_language_config: AutoDetectSourceLanguageConfig | None = None, audio_config: AudioConfig | None = None)

Parameters

Name Description
translation_config
Required

The config for the translation recognizer.

auto_detect_source_language_config

The auto detection source language config

Default value: None
audio_config

The config for the audio input.

Default value: None

Methods

add_target_language

Add language to the list of target languages for translation.

Note

Added in version 1.7.0.

recognize_once

Performs recognition in a blocking (synchronous) mode. Returns after a single utterance is recognized. The end of a single utterance is determined by listening for silence at the end or until a maximum of 15 seconds of audio is processed. The task returns the recognition text as result. For long-running multi-utterance recognition, use start_continuous_recognition_async instead.

recognize_once_async

Performs recognition in a non-blocking (asynchronous) mode. This will recognize a single utterance. The end of a single utterance is determined by listening for silence at the end or until a maximum of 15 seconds of audio is processed. For long-running multi-utterance recognition, use start_continuous_recognition_async instead.

remove_target_language

Remove language from the list of target languages for translation.

Note

Added in version 1.7.0.

start_continuous_recognition

Synchronously initiates continuous recognition operation. User has to connect to EventSignal to receive recognition results. Call stop_continuous_recognition_async to stop the recognition.

start_continuous_recognition_async

Asynchronously initiates continuous recognition operation. User has to connect to EventSignal to receive recognition results. Call stop_continuous_recognition_async to stop the recognition.

start_keyword_recognition

Synchronously configures the recognizer with the given keyword model. After calling this method, the recognizer is listening for the keyword to start the recognition. Call stop_keyword_recognition() to end the keyword initiated recognition.

start_keyword_recognition_async

Asynchronously configures the recognizer with the given keyword model. After calling this method, the recognizer is listening for the keyword to start the recognition. Call stop_keyword_recognition_async() to end the keyword initiated recognition.

stop_continuous_recognition

Synchronously terminates ongoing continuous recognition operation.

stop_continuous_recognition_async

Asynchronously terminates ongoing continuous recognition operation.

stop_keyword_recognition

Synchronously ends the keyword initiated recognition.

stop_keyword_recognition_async

Asynchronously ends the keyword initiated recognition.

add_target_language

Add language to the list of target languages for translation.

Note

Added in version 1.7.0.

add_target_language(language: str)

Parameters

Name Description
language
Required

The language code to add.

recognize_once

Performs recognition in a blocking (synchronous) mode. Returns after a single utterance is recognized. The end of a single utterance is determined by listening for silence at the end or until a maximum of 15 seconds of audio is processed. The task returns the recognition text as result. For long-running multi-utterance recognition, use start_continuous_recognition_async instead.

recognize_once() -> TranslationRecognitionResult

Returns

Type Description

The result value of the synchronous recognition.

recognize_once_async

Performs recognition in a non-blocking (asynchronous) mode. This will recognize a single utterance. The end of a single utterance is determined by listening for silence at the end or until a maximum of 15 seconds of audio is processed. For long-running multi-utterance recognition, use start_continuous_recognition_async instead.

recognize_once_async() -> ResultFuture

Returns

Type Description

A future containing the result value of the asynchronous recognition.

remove_target_language

Remove language from the list of target languages for translation.

Note

Added in version 1.7.0.

remove_target_language(language: str)

Parameters

Name Description
language
Required

The language code to remove.

start_continuous_recognition

Synchronously initiates continuous recognition operation. User has to connect to EventSignal to receive recognition results. Call stop_continuous_recognition_async to stop the recognition.

start_continuous_recognition()

start_continuous_recognition_async

Asynchronously initiates continuous recognition operation. User has to connect to EventSignal to receive recognition results. Call stop_continuous_recognition_async to stop the recognition.

start_continuous_recognition_async() -> ResultFuture

Returns

Type Description

A future that is fulfilled once recognition has been initialized.

start_keyword_recognition

Synchronously configures the recognizer with the given keyword model. After calling this method, the recognizer is listening for the keyword to start the recognition. Call stop_keyword_recognition() to end the keyword initiated recognition.

start_keyword_recognition(model: KeywordRecognitionModel)

Parameters

Name Description
model
Required

the keyword recognition model that specifies the keyword to be recognized.

start_keyword_recognition_async

Asynchronously configures the recognizer with the given keyword model. After calling this method, the recognizer is listening for the keyword to start the recognition. Call stop_keyword_recognition_async() to end the keyword initiated recognition.

start_keyword_recognition_async(model: KeywordRecognitionModel)

Parameters

Name Description
model
Required

the keyword recognition model that specifies the keyword to be recognized.

Returns

Type Description

A future that is fulfilled once recognition has been initialized.

stop_continuous_recognition

Synchronously terminates ongoing continuous recognition operation.

stop_continuous_recognition()

stop_continuous_recognition_async

Asynchronously terminates ongoing continuous recognition operation.

stop_continuous_recognition_async()

Returns

Type Description

A future that is fulfilled once recognition has been stopped.

stop_keyword_recognition

Synchronously ends the keyword initiated recognition.

stop_keyword_recognition()

stop_keyword_recognition_async()

Returns

Type Description

A future that is fulfilled once recognition has been stopped.

Attributes

authorization_token

The authorization token that will be used for connecting to 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.

canceled

Signal for events containing canceled recognition results (indicating a recognition attempt that was canceled as a result or a direct cancellation request or, alternatively, a transport or protocol failure).

Callbacks connected to this signal are called with a TranslationRecognitionCanceledEventArgs, instance as the single argument.

endpoint_id

The endpoint ID of a customized speech model that is used for recognition, or a custom voice model for speech synthesis.

properties

A collection of properties and their values defined for this Recognizer.

recognized

Signal for events containing final recognition results (indicating a successful recognition attempt).

Callbacks connected to this signal are called with a TranslationRecognitionEventArgs, instance as the single argument, dependent on the type of recognizer.

recognizing

Signal for events containing intermediate recognition results.

Callbacks connected to this signal are called with a TranslationRecognitionEventArgs, instance as the single argument.

session_started

Signal for events indicating the start of a recognition session (operation).

Callbacks connected to this signal are called with a SessionEventArgs instance as the single argument.

session_stopped

Signal for events indicating the end of a recognition session (operation).

Callbacks connected to this signal are called with a SessionEventArgs instance as the single argument.

speech_end_detected

Signal for events indicating the end of speech.

Callbacks connected to this signal are called with a RecognitionEventArgs instance as the single argument.

speech_start_detected

Signal for events indicating the start of speech.

Callbacks connected to this signal are called with a RecognitionEventArgs instance as the single argument.

synthesizing

The event signals that a translation synthesis result is received.

Callbacks connected to this signal are called with a TranslationSynthesisEventArgs instance as the single argument.

target_languages

The target languages for translation.

Note
