Microsoft Azure Speech is a powerful tool within the Azure suite that provides speech-to-text, text-to-speech, and speech translation capabilities. It is designed to help developers integrate voice functionalities into their applications, enhancing user interaction through natural language processing.
When working with Azure Speech, you might encounter the error SpeechEndpointNotFound. This error indicates that the specified speech endpoint could not be found, which can halt the functionality of your application relying on speech services.
Typically, this error manifests as a failure in connecting to the speech service, resulting in the application being unable to process speech requests. You might see error messages in your application logs or receive alerts if monitoring is set up.
The SpeechEndpointNotFound error occurs when the application attempts to connect to a speech service endpoint that does not exist or is incorrectly specified. This can happen due to a variety of reasons, such as typos in the endpoint URL, incorrect region configuration, or changes in the endpoint address.
To resolve this issue, follow these steps to ensure that your endpoint URL is correctly configured and accessible:
Check the endpoint URL in your application configuration. Ensure that it matches the format provided by Azure. You can find the correct endpoint URL in the Azure portal under your Speech resource.
Example format: https://.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1
Ensure that the region specified in your application matches the region of your Speech resource in Azure. Mismatched regions can lead to endpoint connectivity issues.
If the endpoint URL has changed, update your application settings to reflect the new URL. This may involve modifying configuration files or environment variables.
After making changes, test the connectivity to the speech endpoint. You can use tools like cURL to send a test request and verify the response.
curl -X POST "https://.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1" \
-H "Content-Type: application/json" \
-d "{...}"
