Before the privatization attempts, the Deutsche Bahn used real announcers on the major train stations.
Now, after decades of cost-cutting, it's pre-recorded audio pieces played by a computer. They sound broken and mismatching (because it's no TTS engine), they fail to be played half the time (and frequent rail users would claim the failure rate at 90%+) and of course the stuff breaks down when something unexpected happens (like emergency rail closures, due to people on the rails, med emergencies, police action, ...).
"The nineteen fifty two ... Southern service to ... Brighton ... is delayed by approximately ... twelve ... minutes due to ... trespassers-on-the-railway. Please listen for further announcements. We apologize for the inconvenience."
(Replace with "a passenger taken ill on a train" or "action by the police".)
"The train approaching platform ... two ... is the ... delayed ... nineteen fifty-two ... Southern ... service to ... Brighton ... calling at ... Clapham Junction, East Croydon, Gatwick Airport, Haywards Heath and Brighton. This train has ... twelve ... coaches. Platform ... two ... for the nineteen fifty-two service to ... Brighton."
I much prefer it to a live announcement. The slightly ... odd pauses are distinctive, but mean derivations from the usual announcement stand out, whilst the whole thing is soporific for commuters. For others, there's the much-needed repetition of the most important bits; the destination of the train is spoken three times.

(I don't like the repeated keep-your-luggage announcements, but maybe they're justified since people are still trying to bomb railways with abandoned luggage.)
But on a station it is possible to only put people in front of the mike who speak accent-free German and English, and to properly adjust and maintain the amps, speakers and wiring.
But also, I disagree with the failure rate of 90+%, from my experience I'd say it works pretty well in 90+% of the time. The system can even announce the "umgekehrte Wagenreihung" ;)
The pronunciation of city names is also rather lacking in many instances, and like you say often doesn't match the surrounding speech.
Aren't these people are voluntary doing this work?
Summing up, my conclusion is the opposite of yours - those jobs would probably exist in pure capitalism.
For instance, until recently ir was unusual for a person to have more than one employer in their lifetime. You entered the workforce just after high school or college and stayed with that employer for the rest of your career. People didn't quit and get a different job. And employers didn't fire people.
The elderly person standing in front of the construction fence warning people to be careful because of the danger used to be construction worker. Maybe they worked their way up in the company until they bumped into the Peter principle or until they physically or mentally couldn't do the job. Then then moved over, around, and down as their abilities declined. The folks who made it high enough to earn a retirement retire. The folks who didn't build a nest egg or spent their egg on Grandma's hospice care, or whatever, depend on the company to keep them in the mail room or sweeping the front lobby or something that will pay the rent and buy groceries.
I have seen many US companies that created Mission Statements and formalized a list of Corporate Values that included Loyalty. But I have seen very few US companies that are loyal to their employees. I suppose there are a lot of ways to be disloyal, but Japanese companies have generally been loyal in maintaining some level of employment to even the least competent of their employees.

Such laws subsidize automation research. As I think this research is undersupplied by a market with access to cheap labour, I'm all for them.
I mean, sure, I'll do whatever if it keeps me and mine alive; but if I'm gonna starve either way, I'm gonna starve hanging out in the sun reading a book.
