Perhaps you could try asking at one of the Swiss organisations for those with impaired hearing, found under "gehörlos schweiz", whether they could recommend an English teacher.

Was also good way to learn. ( and fun )
Picked up a Scottish vocab with all its nuances from my first wife in a dodgy village in West Lothian during the time of the miners strike.
Tried the same in Namibia for a year and a bit - but lost that one after a couple of years.
Suppose as mentioned above - depends on your teacher.
My wife has picked up on my mis matched dialects - Lancashire - born in Liverpool with all the other bits I learned. We have been married over the last 19 years and she has been to all the places where my words came from. She is Chinese Asian - sounds funny when she swears. Her son (25) seems to be able to pick and choose when he uses north english.
Most dialects are diluted nowadays.
Can't help sharing my impressions: quite often I find myself sharing a bus with teenagers descending from the international school for a bit of shopping and 'whateverrrr'. Looks and sounds a bit silly: using words they don't really understand, exaggerating the pronunciation or overusing 'like'... And then the accent, that gives them away... And the location, small town of Zug... It's all just too incongruous.
However, hungryshark, I shall respond to your message and let you decide what's best for you.
And my accent has become much more neutral, and with a slower cadence, over the years of dealing with furriners.

I didn't. That exists??
Wonder how you knew that.

You can find more info by googling.

Back in the day, this was the accent favored by most television news broadcasters - the accent that couldn't be pinpointed, the one that didn't sound like the speaker was from anywhere in particular.
However this seems to have become less prevalent, or important, in recent years. Nowadays one hears many more distinctive accents on television.
Including the screetchy girly voice and worse, vocal fry that I swear did not exist 20 years ago when I left the US but now seem to be ubiquitous in the media. Hurts my ears, please don't try for that no matter how popular it is.

My own accent has apparently been tamped down, the unconscious product of 25 years of living abroad. During a recent trip home I was out with family, ordering from a menu, when the waitress said:
"I love your accent - where are you from?"
Um, I'm Shee-cah-goe born and bred. Wot acksint?
I don't think I sound any different, nor do my family - but apparently folks back home think I sound just a tad like I don't really belong.
