Both Jonathan and Philip Taylor have commented on the broken link to Online Intonation. Thanks to both.
I don’t know why OI has disappeared from the UCL site, but fortunately I have copies of all the files and have spent quite a lot of time over the past few days re-instating OI on the blogjam site. The link in the sidebar now points to the new OI.
I have taken the opportunity to update the program. It now uses mp3 sound files and the HTML5 <audio> tag. I have tested it using Chrome, MSIE, Microsoft Edge, Firefox Opera, Safari and Sea Monkey. Please let me know if you come across any problems.
The only thing left to say is MY BRAIN HURTS!
