It's usually an option installed on aircraft, usually called a "pre-recorded announcement" (PRA) system. Some of these PRAs are triggered automatically (i.e. oxygen mask drop) while others can be loaded/played on a control panel near or on a forward cabin panel. Usually the PRA system will include scripts in English and other languages and includes information for (i) Emergency Landings, (ii) Ditchings and (iii) Decompressions. Accidentally playing the PRAs isn't exactly an unheard of occurrence - I remember reading of a few cases on other aircraft, one of which the problem was traced to a hardware problem rather than someone accidentally setting it off.
The benefit of the system is that it frees crew up to do their emergency demos (brace position, lifejacket donning) or for them to sit down and don an oxygen mask and not have to waste oxygen talking when it's a decompression. Also, the ability to provide instructions in languages other than English is invaluable.
You can hear two PRAs here in Turkish followed by English (the English announcement is probably very similar to what the BA passengers heard):

How about that one
Ladies, Gentlemen and others. This is a prerecorded announcement. At the present speed and altitude we are going to run out of fuel in two hours. We will be crashing if overland or ditching if over water unless the pilots maneuver this aircraft to and land at a suitable airfield before this happens. Please refrain from panicing before the two hours have elapsed, thank you for your attention.

This happened on a QF flight I was once on from HKG to MEL. There was an automated announcement, something along the lines of :
Attention! Attention! This is a decompression sit down! Sit down! Fasten seats belts immediately! Don your oxygen mask, Don your oxygen mask! Fasten seat belts, sit down, sit down, we are descending to a lower altitude …..
Was rather funny really as we were still on the ground with the bridge still attached, but it did cause a slight delay as they couldn’t shut it off so I suspect it was a fault as opposed to accident lol

I was on EZY2271 a couple of months ago with a bit of an old duffer pilot (sounded very ex RAF). 2/3's of the way through he made an announcement, but the tone of his voice was exactly what was needed to get people's attention. Everyone shut up and listened straight away...
..he then proposed on behalf of someone in the plane.
.. and she said yes.
I know this is relatively common, but nice to see none-the-less. (and a good way to get free Champagne - even on ezy)

I am not sure if this is related to the BA announcement, but on MU 346s, there is a pre-recorded turbulence announcement. When entering an area of turbulence, the recording comes on the public address system in both Chinese and English stating something like "we are experiencing some turbulence; please return to your seats with your seatbelts fastened".
While I understand that it is a necessary safety feature, it is annoying as hell, since they use it whenever they hit the slightest bump. However, they seem to not use it past two hours into the flight.

No matter what caused this it is a source of grave concern. How can an airline have procedures that let this happen? If they can not handle it they should not have such prerecorded announcements in my opinion!

Thats a bit OTT, have you never pushed the wrong button on your remote. It should not happen, but it did. It may not have even been a crew member who set it off. I definetely was not a pilot, unless he was fooling around in the cabin.
Oldtimer, I should have known better!
