![]() ![]() Creates an instance of a speech config with specified subscription key and service region. Public async Task SpeechContinuousRecognitionAsync() If (checkBox1.Checked) await SpeechContinuousRecognitionAsync() Private async void checkBox1_CheckedChanged(object sender, EventArgs e) Do you know what is going wrong ? using System The problem is, when I check the checkbox only session started event is generated and nothing else happen, no other events like Recognizing, Recognized, canceled is generating. This winform has one checkbox for speech on/off and performs continuous speech recognition until I close the window. This error also might be caused by network issues.I have this c# winform which uses azure speech to text for converting speech into text. The error most likely occurs because no audio data is being sent to the service. Also, check the request's headers to make sure you specify appropriate values for Content-Type and Content-Length. This error usually occurs when the request body contains invalid audio data. You can try using a different python interpreter or uninstall all python versions and re-install the latest version of python and the Speech SDK. This can be returned, for example, when multiple versions of Python have been installed, or if you're not using a supported version of Python. It's OK to have silence at the beginning of audio, but only when you use continuous recognition. The audio uses an unsupported codec format, which causes the audio data to be treated as silence.In that case, the service stops the recognition after a few seconds and returns InitialSilenceTimeout. The audio begins with a long stretch of silence.For example, the error can be returned under the following circumstances: This issue usually is observed with single-shot recognition of a single utterance. InitialSilenceTimeout via RecognitionStatus $RecoResponse = Invoke-RestMethod -Method POST -Uri $SpeechServiceURI -Headers $RecoRequestHeader -Body $audioBytesĬurl -v -X POST "" -H "Authorization: Bearer YOUR_ACCESS_TOKEN" -H "Transfer-Encoding: chunked" -H "Content-type: audio/wav codec=audio/pcm samplerate=16000" -data-binary you entered a valid authorization token, the command returns the transcription for your audio file, otherwise an error is returned. $audioBytes = ::ReadAllBytes("YOUR_AUDIO_FILE") ![]() 'Content-type' = 'audio/wav codec=audio/pcm samplerate=16000' $RecoRequestHeader = 'Bearer '+ $OAuthToken # $OAuthToken is the authorization token returned by the token service. If you use an authorization token for authentication, run one of the following commands to verify that the authorization token is still valid. If you're using an authorization token for authentication, you might see an authentication error because: If you entered a valid resource key, the command returns an authorization token, otherwise an error is returned. $OAuthToken = Invoke-RestMethod -Method POST -Uri -Headers $FetchTokenHeaderĬurl -v -X POST "" -H "Ocp-Apim-Subscription-Key: YOUR_RESOURCE_KEY" -H "Content-type: application/x-www-form-urlencoded" -H "Content-Length: 0" 'Ocp-Apim-Subscription-Key' = 'YOUR_RESOURCE_KEY' You can verify that you have a valid resource key by running one of the following commands. For more information about confirming credentials, see get the keys for your resource. This access denied error could be observed, for example, when you run one of the Speech SDK for C# quickstarts without setting environment variables.įor baseline authentication troubleshooting tips, see validate your resource key and validate an authorization token. You might also see it when you set the environment variables to something invalid such as your key or region. This error could be observed, for example, when you run one of the Speech SDK for Python quickstarts without setting environment variables. ValueError: cannot construct SpeechConfig with the given arguments (or a variation of this message).Connection requests without a valid Ocp-Apim-Subscription-Key or Authorization header are rejected with a status of 403 or 401. HTTP 403 Forbidden or HTTP 401 Unauthorized.Did you set the speech resource key and region values?.You might observe one of several authentication errors, depending on the programming environment, API, or SDK.
