How's 'qu' and 'ch' pronounced in swedish?
I've heard many audios pronounced 'qu' in 'quiche' only like english k in kind but the book(Teach Yourself) says it is pronounced /kv/. I heard the cd of the book(Teach Yourself) pronouncing ch in 'quiche' like english sh in she but many online dictionaries pronounce it like english h in he? How are these combination pronounced exactly?
Being an unadulterated loanword, quiche should be pronounced as in French, so something like "kish". How people pronounce it in practice might differ from this...
You won't find many instances of qu in Swedish words that aren't recent/obvious loanwords. The pronunciation of ch varies depending on the word: in och it's "k", in chans it's "sh" and so on.
Like most native speakers, you probably don't think about how you pronounce words when you aren't conscious about how you are pronouncing them. Most Swedes have simply learnt that "och is pronounced ock" and they stick by that because it's what's true when the word is being singled out and emphasized. In casual speech, the 'ch' is silent, but you don't think about it because that's the entire point of a casual pronunciation.
Consider these phrases:
"Jag går och fiskar"
"Det var du och jag mot världen"
"Kom och ta mig långt härifån"
"Du ger mig inga löften och du ställer inga krav"
If you say them out loud, as if you were speaking casually, would you honestly pronounce the "och"s here with a k?
Just to be clear, I'm not claiming that och is never pronounced 'ock'. I'm simply stating that most of the time, when we're speaking casually, it's not.
