Observant readers may have noticed that we have changed the comments facility on the blog. The ‘captcha’ code – the random sequence of letters and numbers that must be typed in so it’s clear a human (and not a bot) has posted the comment – now has an audio function.
We’ve installed this in response to a user who had been enjoying the blog until he went to comment and discovered he couldn’t because he is blind. The screen reading software he uses wasn’t compatible with the captcha technology on the blog and he asked if we could implement an audio equivalent.
This proved surprisingly easy to do. It cost $US 59 and took a couple of hours of the developer’s time to install. So if any readers have a blog and would like more information on installing an audio captcha application, feel free to email me directly.
