cURL javascript for IBM to convert Audio to text via "SPEED TO TEXT" Artifical of intelligent of IBM

I have a audio file in my disk. I want to send audio file to website by cURL javascript to convert audio file to text. I learned, and learned that IBM can help me do that. However, I created an account at IBM, I do not know how to create an "authentication-token". Help me create a SPEED TO TEXT project in my IBM account, get {authentication-token} and cURL with javascript for me and here is code of IBM provided: link: [login to view URL] var token = "{authentication-token}"; var wsURI = "wss://[login to view URL]" + "?watson-token=" + token + '&model=en-US_BroadbandModel'; var websocket = new WebSocket(wsURI); [login to view URL] = function(evt) { onOpen(evt) }; [login to view URL] = function(evt) { onClose(evt) }; [login to view URL] = function(evt) { onMessage(evt) }; [login to view URL] = function(evt) { onError(evt) }; function onOpen(evt) { var message = { action: 'start', 'content-type': 'audio/flac', keywords: ['colorado', 'tornado', 'tornadoes'], 'keywords_threshold': 0.5, 'max-alternatives': 3 }; [login to view URL]([login to view URL](message)); // Prepare and send the audio file. [login to view URL](blob); [login to view URL]([login to view URL]({action: 'stop'})); } function onClose(evt) { [login to view URL]([login to view URL]); } function onMessage(evt) { [login to view URL]([login to view URL]); } function onError(evt) { [login to view URL]([login to view URL]); }
