In windows, aliwangwang English has never been a problem. I like the excellent voice reports, but on linux, I am prompted to install the realplay plug-in every time. As a result, the rm voice cannot be heard on the webpage.
Try multiple methods, none, including mplayer-plugin and mediawrap, so you have to install realplayer.
Installation steps:
1) wget http://software-dl.real.com/0522c4cfdf2b78a16c05/unix/RealPlayer11GOLD.bin
(In fact, I have always used proz, and wget can only be a single thread, which is not satisfactory)
2) execute the file and follow the prompts (do not tell me you do not understand the prompt)
[Root @ ErgoN linuxtools] #./RealPlayer11GOLD. bin
Extracting files for Helix installation ........................
Welcome to the RealPlayer (11.0.0.4028) Setup for UNIX
Setup will help you get RealPlayer running on your computer.
Press [Enter] to continue...
3) Installation successful
4) Copy two files to the firefox directory.
Firefox is generally in/usr/lib/firefox-xxxx. For details, refer to your version.
Go to the realplayer Directory:/opt/real/RealPlay/mozilla, which contains two files:
[Root @ ErgoN mozilla] # cp nphelix. so/usr/lib/firefox-2.0.0.8/plugins/
[Root @ ErgoN mozilla] # cp nphelix. xpt/usr/lib/firefox-2.0.0.8/
After the copy is complete, restart firefox.
Final Solution.
