Modify it as follows (remove the audio config parameter): speech_recognizer = speechsdk.Get started with Azure Cognitive Services and its APIs that expose machine learning as a service. It should be noted that if we use the SDK to recognize the voice in the microphone, we will speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config) Speech_recognize_once_from_file_with_custom_endpoint_parameters() Result = speech_recognizer.recognize_once() # For long-running multi-utterance recognition, use start_continuous_recognition() instead. # shot recognition like command or query. # Note: Since recognize_once() returns only a single utterance, it is suitable only for single The task returns the recognition text as result. # single utterance is determined by listening for silence at the end or until a maximum of 15 # Starts speech recognition, and returns after a single utterance is recognized. Speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_input) # Creates a recognizer with the given settings # Creates an audio configuration that points to an audio file.Īudio_filename = "whatstheweatherlike.wav"Īudio_input = speechsdk.AudioConfig(filename=audio_filename) Speech_config = speechsdk.SpeechConfig(subscription=speech_key, region=service_region) Speech_key, service_region = "YourSubscriptionKey", "YourServiceRegion" # Replace with your own subscription key and service region (e.g., "chinaeast2"). # Creates an instance of a speech config with specified subscription key and service region.
#Azure speech to text api and postman code
Similar code can be seen on the official website, but it should be noted that the code only works in Azure Global's Speech service, and specific modifications need to be made for China (see below). Postman obtains Token reference as follows:Ģ, SDK to convert voice files to text (Python example):
If you want to use Authorization Token in REST API, you need to obtain Token first:Īs of February 2020, only East China 2 has Speech service, and its Token endpoint is:
It should be noted that Key or Authorization is a two choice relationship.
Other considerations for building requests:
Note: if you want to convert text to speech, you must use Authorization Token for authentication according to the above table. The Authorization Token is valid for 10 minutes.įor simplicity, this paper uses the OCP APIM subscription key method. Preparation: create Speech service of cognitive service:Īfter creation, two important parameters can be viewed on the page:ġ, The REST API converts voice files to text:įor the Speech API endpoint of Azure global, please refer to:Īs of February 2020, Speech service has been opened only in eastern China 2 regions, and the service endpoint is:įor Speech To Text, there are two authentication methods: SDK mode supports recognition of voice stream and voice file of microphone Today, what we are fighting is Speech To Text. Speech service is a kind of cognitive service, which provides voice to text, text to voice, voice translation and so on.
