Error in the site: The voice is not played automatically
Some times the voice is not played automatically but when I press the ctrl+space (or click on the voice button) then it is played.
It is not only the voice of the text but also the sounds for successful or fail and the voice when I move the mouse on the new words are not played too.
Today I tried both chrome and firefox but none is working! That's while I didn't have any problem yesterday.
I assume you've already checked your settings and ensured that "autoplay" is on? It's possible that it was turned off accidentally--just check. If it's turned on, then try restarting your browser or even your computer. Sometimes the flash just poops out.
Thanks for your response Yes !!! The option "Speaker" was turned off but I don't know who did that! :D Actually I didn't know that these options exist and I had never gone there! For some reason it was changed accidentally.
