It appears the Java applet has some issues (as of today Dec 25th) even after I installed latest java plug in on my laptop (Windows 8.1 all updates done). I had to minimize Internet explorer and maximize it for the Java applet to show properly.
The other method appeared cumbersome and I could not figure out easily. Hence I still somehow uploaded few speech recordings using Java applet.
May be one more method using some other software would be helpful. I am fine downloading and installing a recording software like this applet on laptop.
