 Look at these English words. Do you pronounce them with a voiceless post alveola african and say cheap, chin and chop? Or is your version something like sheep, shin or shop? In which case even different meanings may be the result. Well, if this is the case, then you probably pronounce German words that begin with chur, like cheche or chus, in a similar fashion and say cheche and chus. So what can we do about this? The problem is a distributional one. Both English and German have the phoneme chur and an alofon which occurs in final position as an English match or in German much. However, whereas English also has an initial alofon as in chief, this alofon does not occur in German. In fact, it is often realized as chur as in chef. How can we solve this problem and pronounce the african even word initially? Well, apart from the fact that we can produce chur word finally as in match, kitsch or quach, we can use these German words as a starting point for words with initial chur. The trick is quite simple. Say match and add an English word starting with chur. So we have, for example, much cheap. Now drop the initial syllable ma and you're there. Ma cheap becomes cheap. Alternatively, you can use a short glottal stop in front of the English words and the effect is virtually the same. You get a cheap, a chin and a chop. So it's simple, isn't it? I hope my advice helps and you will no longer find it difficult to produce present-day English words with an initial chur.
