Somebody on YouTube asked where I got the file to make my Macs sing happy birthday to the London Science Museum. I realised I’d forgotten to upload it anywhere. Or perhaps I didn’t think people would be interested, since in general if they wanted their Macs to sing happy birthday, they’d want to customise the name. The software I wrote to do this (and other things) is really still a prototype unintuitively bolted onto an unrelated prototype, with the default CoreData interface, so I’d rather not release it yet. But just in case you do want your Mac to sing happy birthday to the London Science Museum, here’s the file. There are instructions in the file on how to get it to sing.
I also just made this file where you can put the name of your choice instead of the London Science Museum; just search for ‘your name here’ in the file, and change it. It will just speak the name rather than singing it, since to get it to sing it you’d have to figure out how to write the name in MacInTalk phonemes.
Alternatively, if you want to personalise the song while still having the name sung, you could record your Mac singing to a sound file using the ‘Text to Audio File’ Automator action, and then open that in GarageBand and splice in a recording of yourself singing the appropriate name.
Addendum: I just thought of another possibility: you could use the Repeat After Me application (which comes with the developer tools) to get your Mac to sing the name however you do. This is not what I used for the rest of the song, since it’s made with normal speech intonation in mind rather than singing, and it gets quite tedious for anything long, but it is a very cool program and would be great for just recording the name.
