SpeechRecognizer Class

A speech recognizer. If you need to specify source language information, please only specify one of these three parameters, language, source_language_config or auto_detect_source_language_config.

Inheritance

Recognizer

SpeechRecognizer

Constructor

SpeechRecognizer(speech_config: azure.cognitiveservices.speech.SpeechConfig, audio_config: Optional[azure.cognitiveservices.speech.audio.AudioConfig] = None, language: Optional[str] = None, source_language_config: Optional[azure.cognitiveservices.speech.languageconfig.SourceLanguageConfig] = None, auto_detect_source_language_config: Optional[azure.cognitiveservices.speech.languageconfig.AutoDetectSourceLanguageConfig] = None)

Parameters

speech_config

Required

The config for the speech recognizer

audio_config

default value: None

The config for the audio input

language

default value: None

The source language

source_language_config

default value: None

The source language config

auto_detect_source_language_config

default value: None

The auto detection source language config

Methods

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.

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() -> azure.cognitiveservices.speech.SpeechRecognitionResult

Returns

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() -> azure.cognitiveservices.speech.ResultFuture

Returns

A future containing the result value of the asynchronous recognition.

Attributes

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 SpeechRecognitionCanceledEventArgs, instance as the single argument.

recognized

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

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