Text To Speech USP error: timeout waiting for the first audio chunk

MarkL 56

I have been using some slightly modified sample code to generate speech from text. It has been working without issue. I returned to the project after maybe a week, and it is now receiving timeouts:

CANCELED: Reason=Error
CANCELED: ErrorCode=ServiceTimeout
CANCELED: ErrorDetails=[USP error: timeout waiting for the first audio chunk]
CANCELED: Did you update the subscription info?

The sample code I am using is here: https://learn.microsoft.com/en-ca/azure/cognitive-services/speech-service/get-started-text-to-speech?tabs=windows%2Cterminal&pivots=programming-language-csharp

I have tried:

Regenerating API keys
Creating new resource group
Creating new services

All yielding the same result.

Is anyone else having similar issues? I have also tried with Python examples with the same result.

Thanks in advance!

I am having the same issue - was working fine till about 2 days ago (which coincided with a new release of the nuget for the Microsoft.CognitiveServices.Speech package to 1.24.0 (I have also tried upgrading to this and the same issue exists in 1.24.0 also).

I also get an error if I call :

var synthesizer = new SpeechSynthesizer(_config);

var voices = await synthesizer.GetVoicesAsync();

voices.ErrorDetails shows this after the call to getvoicesasync returns no voices:

Error in sending ahttp request Details Failed with error HTTPAPI_OPEN_REQUEST_FAILED

This was working fine previously (I have also tried regenerating the key, checking the region etc etc....these are all fine.

One thing i will mention is that my appservice is sitting in "Australia southeast" and the speechservice is housed in "Australia East" - I'm not sure if others have these in 2 different regions or if thats even related?

If I go into azure portal and look at the speech service on the networking tab it says
"Custom Domain Name is required for VNet"

Now I have not changed anything between when it was working and now - but maybe this is somehow related after some updates?

Do others seeing this issue have the same?

Hello.

This same issue has hit our product starting the same day as MS Ignite. We have been using the 1.22.0 C++ SDK since it was released and without any changes to our code, and are now receiving the "USP error: timeout waiting for the first audio chunk" on some of our PCs, but not others. We are using the eastus region and the Subscription Key and Region authentication.

Today we upgraded to the 1.24.0 C++ SDK and are still seeing the error on the same PCs that had it with the 1.22.0 C++ SDK.

Please update this thread as the issue is being worked on. This is impacting a shipping product.

Thanks.

我现在依旧正在被这个问题所困扰，我无法使用新推出的补丁，因为我没有使用服务器，我将C#的SDK放在程序里，然后我的用户的电脑会直接进行音频的合成，我现在该怎么做？我需要继续等待吗？I am still being plagued by this problem, I can't use the newly released patch because I am not using the server, I put the C# SDK in the program and then my user's computer will do the audio synthesis directly, what do I do now? Do I need to keep waiting?我現在依舊正在被這個問題所困擾，我無法使用新推出的補丁，因為我沒有使用服務器，我將C#的SDK放在程序裏，然後我的用戶的電腦會直接進行音頻的合成，我現在該怎麽做？我需要繼續等待嗎？

oh shoot. Ok you are in the same boat.
Use the same nuget.

Should we track this as a separate issue? Since the library is busted now? @YutongTie-MSFT ?

We currently have this problem on Windows Server 2019.

Can someone please confirm the KB to install to fix it on this OS (KB5020435 doesn't support Windows Server 2019).

Or please confirm the KB to uninstall that caused the problem in the first place.

Thank you.

Hi Ian, I installed this update: windows10.0-kb5020438-x64_56438b53dbad8a919ebe3b9ba8b793fafde11729.msu -> which is shown as Windows 2019 without issue, this fixed the issue for me.

It took about an hour to install.

Same with me.

My desktop program that used the Azure Text-to-Speech stopped working and getting time out or "can't connect" messages.

My region is "uksouth". I am using Windows 10 and C#.

Everything is up to date on my end.

So is it just a case of waiting until Microsoft fixes the issue?

Hi @YutongTie-MSFT ,
Why is microsoft not responding to requests to fix azure cognitive services which is currently broken as per the post by me on Oct 14 2022 at 10:31 PM - the service literally can not even get a list of voices any more ...... azure is it's a paid service and its been down for weeks now! - why is no one responding to it.....starting to get frustrated users here now.

Do you need anything more from me -

Its so simple to recreate - create an app using
Microsoft.CognitiveServices.Speech package to 1.24.0

then make a couple of api calls:

var synthesizer = new SpeechSynthesizer(_config);

var voices = await synthesizer.GetVoicesAsync();

and it errors since this TLS stuff was broken weeks ago .....

It is effecting my app (and others on this stream e.g. @rlalancette and @yyseasia008 and there seems to be a total void on it being looked at?

What do i need to do next please?

Hello @Mike O`leary

Thanks for your follow-up but I have responded to you under another comment from you -

The 22H2 feature release from September 20 does not actually contain the fix for some of the system versions. You need to install the preview feature release (KB5018496) from October 25th to get the fix for 22H2:
https://support.microsoft.com/topic/october-25-2022-kb5018496-os-build-22621-755-preview-64040bea-1e02-4b6d-bad1-b036200c2cb3

Windows 11 21H2:

Could you please try that? If it not works, could you please share your system version so that I can forward it to Windows team? Thanks

Hi @YutongTie-MSFT ,
When I run the update it says "This update is not applicable to your computer"
Below is my details

Edition Windows 11 Pro
Version 22H2
Installed on ‎3/‎11/‎2022
OS build 22621.674
Serial number REDACTED (I can supply this offline if you need it)
Experience Windows Feature Experience Pack 1000.22634.1000.0

Also - I just want to make sure that you are clear - I am running the application that is failing as an azure web application - so these details I have supplied are off my development PC - NOT the azure web server that the application is failing on - I would think the patch needs to be applied to the azure runtime environment for it to make my app work?

Hi Caroline, unfortunately until next month's service packs, you must install the out-of-band patch or remove the October CU patch.

@YutongTie-MSFT We are not running this on our local machine. We are calling into azure using a nuget package.

The following nuget package is broken!
https://www.nuget.org/packages/Microsoft.CognitiveServices.Speech
I upgraded to 1.24.1 and it is still broken.

Should we open a different issue to track this nuget package?

Hi @rlalancette and @YutongTie-MSFT
I have a more information that may help microsoft fix azure - the standard azure portal is showing the same error:

To replicate it create a speech service in azure.
Open the newly created speech service.
Go to the 'overview' option in the list on the left (eg the overview for the speech service)
Click on the 'discover' tab on the overview page.
In the discover tab there is an azure option to test the speech service - it is entitled "Try the Speech to Text Demo"

This shows an error on the azure page as per below:

InvalidUriThe requested URI does not represent any resource on the server. RequestId:REDACTEDID Time:2022-11-11T00:21:06.7568420Zhttps://portalextensionconfigs.blob.core.windows.net//demos/SpeechDemo.html?trustedAuthority=https://portal.azure.com

NOTE: I redacted the ID as i dont know if that is a private key or not - its essentially a guid.

So at this point even azure speech portal page has the same error trying to get a voice.....

I hope this helps to find the issue - I'm now getting pressure to move this to AWS as its been weeks - I don't want to because its a ton of work....... please help resolve it.

Hello @Oxueillirep @stephanus @Tanmay Dixit @Strada Francesco @Egil Sandfeld @MarkL @Andrey Bobrovsky @yyseasia008 @Tuan（トアン） Hoang

Thanks for the report, everyone! There has been some extensive investigation over the past 12-16 hours, and it's been found that this is a result of a Windows 10/11 patch on Tuesday that changed the behavior of TLS in the operating system. Speech SDK is not the only ones impacted and a wide variety of TLS-dependent service use started failing with the latest patches.

This issue is specific to those Windows clients with the latest updates from Tuesday.

The Windows team is working on the root problem, and we expect a fix to be rolled out to Windows fairly quickly (for a Windows update--there's no ETA but we should assume it's still on the order of a week or two). In the interim, rolling back either of the above KBs can resolve the issue, and forcing TLS 1.2 in Windows's Internet Settings may be another way of working around the problem.

Besides above, API and MacOS should work properly. I hope those helps! I will post more updates once I get more.

[Update for Windows 11 22H2]
The 22H2 feature release from September 20 does not actually contain the fix. You need to install the preview feature release (KB5018496) from October 25th to get the fix for 22H2:
https://support.microsoft.com/topic/october-25-2022-kb5018496-os-build-22621-755-preview-64040bea-1e02-4b6d-bad1-b036200c2cb3

For windows 10 22H2, please try KB5020435 - thanks for Carlos to post the exact link

Thank you, but please elaborate on when end-users get this fix.

It seems right now, that to fix it a manual update is required?
Will end-users ever get an "auto" update via Windows Update containing this fix?

Hi, I am a developer using the speech SDK and this bug has prevented most of my users from using the most important speech synthesis service in my software, we have suffered a major loss as a result, I would like to ask if users can fix this issue afterwards through automatic updates in windows? Or do I have to ask all my users to install the patch manually on their computers?

子狸 1 Reputation point

2022-10-19T22:28:57.61+00:00

By the way I can't use the patch you mentioned above because I don't use the server, I package the SDK directly in my program and give it to the user's computer for speech synthesis

@Buck Yeh The update KB5020435 is a out-of-band update, you can't install it from normal Windows update channel. You have to go to Windows Update Catalog to search KB5020435 and download it. You can check my blog post (in Chinese) for more detail: https://blog.darkthread.net/blog/win-release-msg-center/

If it's installed successfully, you should see KB5020435 in the update history.

@YutongTie-MSFT hello, I have the same problems, windows 21H2 with the latest update (done today.)

azur text to speech (cognitive service) still output the error USP error: timeout waiting for the first audio chunk (using python)
What can be done ? comments here suggest 22h2 doesn't solve their problems, where is the tutorial to get the fix ?

have a nice day,

Hi @YutongTie-MSFT - can you make sure they are aware we cant even get a voice list since this broke e.g.

Using cognitive services ON AZURE

var synthesizer = new SpeechSynthesizer(_config);

var voices = await synthesizer.GetVoicesAsync();

voices.ErrorDetails shows this after the call to getvoicesasync returns no voices:

Error in sending ahttp request Details Failed with error HTTPAPI_OPEN_REQUEST_FAILED

My solution is totally dead due to this upgrade - we need a fix on azure ASAP - I cant use txt to speech because i cant get a voice list at this stage.

Hello,

My team and I are still unable to get past the timeout errors for our program.
We are unable to update to Windows 11 because of restrictions on other vital software. Our current version of windows is Windows 10 Pro version 22H2 and we have the latest available updates installed (as of this post). The updates do not fix our issue with the Text to Speech.
Will there be a fix for Windows 10 version? Or is there another problem that needs to address first?

Caroline

Same for me.
Windows 10, Version 22H2 is the newest I can get, and the issue still remains after multiple weeks.

Is this a Microsoft marketing stunt?
Destroy an important API in Windwos 10 and only provide a fix for Windows 11, so everybody needs to upgrade?
