Azure Speech to Text Service
Picture from ThisIsEngineering
Yet another coding exercise on Azure Cognitive Services. This time, we have Azure Speech to Text Service in Python. I am referencing this code.
1. Initialize Setup
First and foremost, I need to do the following
- Create a resource group
- Create Azure Cognitive Translation Services in this resource group.
- Copy the key and location values as shown below (Note endpoint value is not needed).
For simplicity, I have two values as environment parameters, AZURE_SPEECH2TEXT_KEY, and AZURE_SPEECH2TEXT_LOC.
2. Code
FYI, I am using MacOSX
2.1 Install library
pip3 install azure-cognitiveservices-speech==1.23.0
2.2 Code
import azure.cognitiveservices.speech as speech_sdk import os if __name__ == "__main__": speech_key, service_region = ( os.environ["AZURE_SPEECH2TEXT_KEY"], os.environ["AZURE_SPEECH2TEXT_LOC"], ) speech_config = speech_sdk.SpeechConfig( subscription=speech_key, region=service_region) speech_recognizer = speech_sdk.SpeechRecognizer(speech_config=speech_config) print("Say something...") result = speech_recognizer.recognize_once() if result.reason == speech_sdk.ResultReason.RecognizedSpeech: print("Recognized: {}".format(result.text)) elif result.reason == speech_sdk.ResultReason.NoMatch: print("No speech could be recognized: {}".format(result.no_match_details)) elif result.reason == speech_sdk.ResultReason.Canceled: cancellation_details = result.cancellation_details print("Speech Recognition canceled: {}".format(cancellation_details.reason)) if cancellation_details.reason == speech_sdk.CancellationReason.Error: print("Error details: {}".format(cancellation_details.error_details))
3. Test
I was testing it out (speaking into the mic), and one of the test outputs is
4. Conclusion
Being a native English speaker and having my voice recognized by this service is nice! Coding-wise, it cannot be simpler than what we have here. I will do trying out text-to-speech service next.
