 The **audio** method improves the accessibility of the image CAPTCHA by adding a .wav download. The .wav file plays the letters of the CAPTCHA read in the [[wp>NATO phonetic alphabet]]. Please note, that because of the way how the wave file is generated it might be easier to automatically decode than the image.
+The **svg** method works similar to the image method, but creates an inline SVG of the random letters. It should be much easier to read for humans. Until spammers catch up OCR'ing embedded SVG it should be relatively safe against automated solving. It has the same accessibility problems as the image method.
+The **svgaudio** method combines the svg method with the audio method, providing an alternative audio version next to the SVG image.
 The **figlet** method creates an ASCII art rendering of the text. It has very bad accessibility and is relatively easy to defeat by a script, but is funny to look at ;-)

 Read the documentation again. The default settings **js** method uses a [[http://www.google.com/search?q=javascript+invisible+captcha|hidden CAPTCHA]]. There's nothing to see.
