Azure AI Speech Studio TextToSpeech Error 400 Synthesis failed

Anonymous

I'm trying to generate many multilingual voice and for the majority of the multilingual I get this message : Response status code does not indicate success: 400 (Synthesis failed. StatusCode: NotFound, Details: service does not exist: service endpoint de-de-combogroup48neural-clusterip.tts-standardvoice-backend.svc.cluster.local:9001 failed dns validation.).

When I use multilingual as English (USA) as default it's working great. But for all the others it failed.

Please fix this feature.

Hello @Kack Cédric , Thanks for using Microsoft Q&A Platform.

Could you please provide more details about the TTS feature you're working on, including the Azure resource region and the sample voice to reproduce the same on our end?

We are also experiencing problems (error 400) for multilingual neural voices (de-DE-FlorianMultilingualNeural, SeraphinaMultilingualNeural) - starting 10am CET. Even on the console, when you try out the voices with your own text, there is no audio output. We are using endpoint https://germanywestcentral.tts.speech.microsoft.com/cognitiveservices/v1

Same for de-DE-FlorianMultilingualNeural and de-DE-SeraphinaMultilingualNeural via endpoint https://germanywestcentral.tts.speech.microsoft.com/cognitiveservices/v1

Even when you try them on the console (custom text, not the pre-recorded audio), there is no audio output. delivered. I also tested various other MultilingualNeural voices and several had the same problem.

At test request would look like this (resulting in HTTP 400): $ curl -i -X "POST" "https://germanywestcentral.tts.speech.microsoft.com/cognitiveservices/v1" \ -H 'Ocp-Apim-Subscription-Key: XXX' \ -H 'X-Microsoft-OutputFormat: raw-8khz-8bit-mono-mulaw' \ -H 'Content-Type: application/ssml+xml' \ -H 'User-Agent: virtualq/tts' \ -d '<speak version=\'1.0\' xml:lang=\'en-US\'> <voice xml:lang=\'en-US\' name=\'de-DE-FlorianMultilingualNeural\'> Test </voice> </speak>'

Hello @VasaviLankipalle-MSFT,

I'm trying to use Azure AI's text-to-speech functionality to create audio content.

I'm doing tests to choose the multilingual voices that we will use officially in our organization.

So I don't have a specific case. However, I notice that when I filter my voice search by entering Multilingual in the search field and leave English (United States) for the language, all of these voices work when I use the French (canada) language skill. But when I change the language filter to French (Canada) all the other voices proposed do not work regardless of the language skill.

Hope this can help.
