The VoxForge Speech Submission Application requires the following:
Java version 1.5 or greater;
Java enabled in your browser;
If you are using a Linux that has an open source Java that does not support signed applets (e.g. OpenJDK or IceTea), then you need Sun's JRE (Java Runtime Environment);
Special Java configurations if running behind a proxy server (see below for instructions); and
Special setup for Linux USB microphones (see below).
How to determine if Java is installed on your PC
If Java is working properly on your browser you will see a grey
rectangle below this paragraph with one line of text that says something like "Java Version 1.5.0_12 from Sun Microsystems Inc.":
symptom: you see text stating something like: "Browser has Java disabled"
problem: the Java Run-time Environment ("JRE") is installed on your computer, but it is disabled in your web browse, or you don't have a java plugin installed in your browser
solution:
1. To enable Java in your browser, click one of these links:
Internet Explorer - Sun's Java download will automatically configure IE for Java.
FireFox
- You need to click the white box or click the "missing plugins" button
at the top right-hand corner of the page. FireFox will guide you to
download a Java Run-time environment for you PC.
Solution: Go to Sun's Verify your Java Installation and follow the instructions on the page to upgrade the version of Java on your computer.
Other Problems
symptom: can't see the waveform display on Java applet
Problem: Zoom settings in browser window are incorrectly set.
Solution: FireFox: View > Zoom: click "Zoom in" until waveform display is visible (can also use your mouse wheel to change zoom settings).
Proxy Servers
If your browser is behind a proxy server, please set up your Java JRE as follows:
Open
the JRE control panel:
Windows: located in system control
panel under Java (Start>Control Panel>Java - If this isn't
visible, ensure you're using "Classic View", and not "Category View");
Linux:
located in System>Preferences>Java (or execute jcontrol from the command line);
Click
the "General" tab, then click the "Network Settings..." button.
Enter proxy settings as directed by your local system
administrator;
Restart your web browser.
Linux and USB Microphones
The USB microphone problems might be fixed in the newest Fedora 12 (i686) release... see this video:
The Speech Submission applet assumes that you will use your default audio source. On Fedora 12, you can set your default audio source for your USB microphone in your Sound Preferences:
System > Preferences > Sound
click the 'Input' tab to 'choose a device for sound input'
select your USB device
In older Linux distributions, if your computer had an analog microphone jack (on your motherboard or on an audio card) the distro assumed that this was your default audio source, even if you plugged in a USB microphone (it basically ignores the audio from your USB microphone). The easiest way to fix this is to upgrade to the newest stable distro.
If you do not want to upgrade your distro, here are some possible approaches that might correct this:
Disable your motherboard's microphone jack (or the audio card itself) in your system bios (this changed on the menu you can select when your computer first starts up);
