InitialSilenceTimeout error using SDK but works fine in short audio REST API

Caesar Cavales 30

Hello,

I have been having issues using the SDK with an audio returning with a InitialSilenceTimeout error. I have the setting below(as I saw it being discussed in a different thread)

speechConfigHandler.setProperty(PropertyId.SpeechServiceConnection_InitialSilenceTimeoutMs, '45000');

but I'm still getting the same error detail. I used the same audio in our REST API and it was transcribing correctly.

Please advise.

Thanks!

Caesar Cavales I think the maximum value that can be set is only 15 seconds. Please see this note from the documentation.

The end of a single utterance is determined by listening for silence at the end or until a maximum of 15 seconds of audio is processed.

Also, the property is to be set on the speechConfig instead of its handler as mentioned below:

speechConfig.SetProperty(PropertyId.SpeechServiceConnection_InitialSilenceTimeoutMs, "10000");

@romungi-MSFT Gotcha. I actually found that value from a comment you had in this link.

Sorry, the name might be confusing. the "handler" is just how the variable is named in

const speechConfigHandler = SpeechConfig.fromEndpoint(url, subscriptionKey);

Then I did this after the line above

speechConfigHandler.setProperty(PropertyId.SpeechServiceConnection_InitialSilenceTimeoutMs, '10000');

I tried changing the value to "5000", "10000". And it still failed on "InitialSilenceTimeout" error. This is the audio file I used. The same audio I used in REST API and it was able to transcribe correctly

@Caesar Cavales The following should work. I have noticed you are using single quotes for the value. Not sure, how this is being handled by the SDK.

speechConfig.SetProperty(PropertyId.SpeechServiceConnection_InitialSilenceTimeoutMs, "10000");

If it still fails, I suggest raising an issue on the SDK repo with your code sample.

@romungi-MSFT I made it double quotes to test and still resulted with the same error message. I will be raising an issue in the SDK. Please confirm if this is the correct link. https://github.com/Azure/azure-sdk-for-js Thanks!

@Caesar Cavales If you are using JS SDK then the repo is https://github.com/microsoft/cognitive-services-speech-sdk-js/tree/master

Also, check this sample from tests in the repo.

@romungi-MSFT it doesn't seem like I can create an issue. The "New issue" button is disabled for me.

@Caesar Cavales It should be enabled, it is a public repo. Could you try using any other user id?
