The VoxForge Speech Submission applet is a signed Java applet. Unfortunately, OpenJDK's (free implementation of Sun's Java run-time environment) browser plugin, gcjwebplugin, does not yet support signed plugins.

From the Fedora Project Wiki:

Handling Java Applets

Upstream OpenJDK does not provide a plugin. The Fedora OpenJDK packages include an adaptation of gcjwebplugin, that runs untrusted applets safely in a Web browser. The plugin is packaged as java-1.6.0-openjdk-plugin.

  • ...
  • The gcjwebplugin adaptation does not support signed applets . Signed applets will run in untrusted mode. Experimental support for signed applets is present in the IcedTea repository, but it is not ready for deployment in Fedora.
  • The gcjwebplugin security policy may be too restrictive. To enable restricted applets, run the firefox -g command in a terminal window to see what is being restricted, and then grant the restricted permission in the /usr/lib/jvm/java-1.6.0-openjdk- file.
Therefore, the Speech Submission app will not run with OpenJDK.  You will need to download a current version of Sun's Java run-time environment and link it to your browser using the instructions on Sun's site.

See these FAQ entries for instructions on how to install Sun's Java so that signed applets will work properly:
