I'm trying to include speaking into my webpage. To do this I am trying to use iframes pointing to http://text-to-speech.imtranslator.net/ I plan to make it invisible so it doesn't affect the layout and then interact with it with javascript to set the value of the text area & click the button to make it speak.
An answer on here said to do "myframes.window.getDocumentById". However using window/getDocumentById leads to "permission denied" with accessing that property. Could it be that the website/browser (I use firefox) has disabled such interactions? Or am I just doing it wrong?
