I am trying to use Watson text to speech service in a javascript code. However, I am stuck trying to get it working.
If I use the following code:
 $.ajax({
                url: 'https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize',
                type: 'POST',
                headers: {"Content-Type": "application/json", "Accept": "audio/*", "Authorization": "Basic SomethingSomethingSomething=="},
                text: msgData.message[0].cInfo.text,
                output: 'output.wav',
                success: function() { 
                    console.log("text to voice complete"); 
                    var audio = new Audio('output.wav');
                    audio.play();
                }
            });
I get:
Failed to load https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize: Request header field Authorization is not allowed by Access-Control-Allow-Headers in preflight response.
Please note that I could easily get a request like this is working from Restlet.
However, if I use:
$.ajax({
                        url: 'https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize',
                        type: 'POST',
                        user: {"something": "something"},
                        headers: {"Content-Type": "application/json", "Accept": "audio/*"},
                        data: {"text": msgData.message[0].cInfo.body},
                        output: 'output.wav',
                        success: function() {
                                console.log("text to voice complete");
                                var audio = new Audio('output.wav');
                                audio.play();
                        }
                });
I get:
stream.watsonplatform.net/text-to-speech/api/v1/synthesize:1 POST https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize 401 (Processed)
