"Contemporary use of the term(s) in English == 
 Are there any musicology (or lexicology) sources which discuss how usage of the words sprechgresang and sprechstimme have evolved? The word sprechstimme crops up from time to time in mainstream music articles (about pop, rock, blues, etc). It's usage there seems to be more general (and perhaps incorrect) than the stricter historical sense described here. I'm not a musicologist, but merely notice that the term is used in a broader sense than this article covers. Some references:
