Bing Speech API (Text To Speech) rest api response code 503

Question

When i request the bing speech rest api, I got an 503 error and do not return a result. 
In the past, it's worked.But the recent response has received 503 code.

The api - https://speech.platform.bing.com/synthesize

I found if the ssml's lang is try to use 'zh-TW', it is not worked.
But if the ssml's lang is try to use en-US, it is worked.
Any difference? or how to resolve?

Hi fourjay,

Can you share your code snippet, X-Microsoft-OutputFormat used, and your XML file you are sending to the API?

Thanks.

James

Can you try this XML payload? I did find a control character when copying the content.  It looks similar, but what I did was copied the sample from here and made the necessary changes:

https://docs.microsoft.com/en-us/azure/cognitive-services/speech/api-reference-rest/bingvoiceoutput

<speak version='1.0' xml:lang='zh-TW'><voice xml:lang='zh-TW' xml:gender='Female' name='Microsoft Server Speech Text to Speech Voice (zh-TW, Yating, Apollo)'>微軟是全球科技產業的領航者，提供全球領先的軟體、服務、設備和解決方案，自 1975 年成立以來，一直致力於幫助個人和企業用戶，全面發揮科技潛能，實現夢想。四十多年來，微軟一直專注於技術創新與變革，透過卓越的軟體、設備和服務，能夠幫助用戶提昇生活和工作生產力，讓數億的使用者真正受益於科技。微軟公司總部位於美國華盛頓州 Redmond，在全世界超過 190 個國家和地區設有分公司或是分支機構，擁有超過 125,000 名員工。微軟執行長 Satya Nadella 在上任後提出了新願景：「在這個行動優先、雲端至上的世界裡，微軟的核心競爭力，就是成為一個提供生產力與平台的公司，幫助在這個地球上的每一個人到每一個組織，都能貢獻更多、成就更大。」台灣微軟成立於 1989 年，身為政府、學校與企業最值得信賴的夥伴，始終致力於幫助台灣提升創新力、競爭力以及促進經濟繁榮，共同來亮點台灣！</voice></speak>

Answer 5

This is strange.

Can you try the Azure version of speech service? https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/overview

You will need to go back into the portal and spin up this service, use a different key, and endpoint URI.

REST API doc here: https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/rest-apis

Thanks.

James

Answer 6

Hi James:

I try to request different endpoint , it still not work.

But I found if the content keep only very few words, it can work.And I know the 1024 characters limit, but the content I request should not be exceed.

What could be the reason?

Thanks.
