Making Ajax REST calls

Question

How I can convert the following cURL into an ajax REST call?

    curl -u "{username}":"{password}" \
-H "content-type: audio/wav" \
--data-binary @"/path/to/file.wav" \
"https://stream.watsonplatform.net/speech-to-text/api/v1/recognize"

I added few of it to below ajax call, I do no know how to add the rest of it, specially the part mentioned in -H and --data-binary @

function restCall()
            {
                $.ajax
                ({
                    type: "GET",
                    url: "https://stream.watsonplatform.net/speech-to-text/api/v1/recognize",
                    dataType: 'json',
                    username: "xxxx",
                    password: "xxxx",

                    success: function (data){
                        alert(JSON.stringify(data)); 
                    }
                });
            }
