The text recognized from the audio sample file is as below. Result = speech_recognizer.recognize_once() Speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config) Speech_config = speechsdk.SpeechConfig(subscription=speech_key, region=service_region)Īudio_config = (filename='whatstheweatherlike.wav')
#AZURE SPEECH TO TEXT PYTHON EXAMPLE INSTALL#
I installed the current version 1.6.0 of Azure Cognitive Services SDK for Speech via pip install azure-cognitiveservices-speech.
#AZURE SPEECH TO TEXT PYTHON EXAMPLE CODE#
Modify it as follows (remove the audio config parameter): speech_recognizer = speechsdk.There is an offical audio sample named whatstheweatherlike.wav which you can get from samples/csharp/sharedcontent/console/whatstheweatherlike.wav of the GitHub Repo Azure-Samples/cognitive-services-speech-sdk.Īnd here is my sample code I wrote and partial refered to the offical tutorial Quickstart: Recognize speech with the Speech SDK for Python. 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() Print("Recognized: ".format(cancellation_details.error_details)) # 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. Prepare to use the Speech service In Visual Studio Code, in the Explorer pane, browse to the 07-speech folder and expand the C-Sharp or Python folder depending. Select Speech item from the result list and populate the mandatory fields. Speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_input) In the search bar type 'Speech' and in the result list you will Speech item available. from gtts import gTTS import os mytext Welcome to geeksforgeeks language en myobj gTTS (textmytext, langlanguage, slowFalse) myobj.save ('welcome. Now we are all set to write a sample program that converts text to speech. # Creates a recognizer with the given settings To install the gTTS API, open terminal and write pip install gTTS This works for any platform. # 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. 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. For your information, most of the advanced Speech-to-Text APIs comes with word-level timestamps. The Authorization Token is valid for 10 minutes.įor simplicity, this paper uses the OCP APIM subscription key method. In fact, big players such as Google and Microsoft provide their own Speech-to-Text API as part of their technologies. 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.
