I am working with Microsoft Cognitive Services and submitting some TTS over the Rest API. If I submit the xml listed below directly to the service via postman, it works fine, if I submit the xml below via my java code I get:
HttpResponseProxy{HTTP/1.1 400 Synthesis failed. StatusCode: FailedPrecondition, Details: SSML parsing error: 8004507A. [Server: openresty/1.15.8.2, Date: Mon, 07 Jun 2021 20:48:40 GMT, Content-Type: text/xml, Transfer-Encoding: chunked, Connection: keep-alive, Strict-Transport-Security: max-age=15724800; includeSubDomains] ResponseEntityProxy{[Content-Type: text/xml,Chunked: true]}}
The java code works flawlessly if I do not inject the SSML
<phoneme alphabet="ipa" ph="təˈmeɪtoʊ"> tomato </phoneme>
The only thing I can think of going wrong is the Entity for the body. With postman this is a raw body. Is there something else I should be doing for the body in java?
HttpPost httpPost = new HttpPost("https://eastus.tts.speech.microsoft.com/cognitiveservices/v1");
httpPost.setEntity(new StringEntity(xml));
httpPost.addHeader("Content-Type", "application/ssml+xml");
httpPost.addHeader("Ocp-Apim-Subscription-Key", key);
httpPost.addHeader("X-Microsoft-OutputFormat", "audio-48khz-192kbitrate-mono-mp3");
org.apache.http.HttpResponse resp = httpclient.execute(httpPost);
