The standard pronunciation of "street" in American English is with a clear "str" sound. The "t" sound is fully articulated, and there's no "sh" sound involved.
Here's what might be leading to this confusion:
* Regional accents: Some regional accents might have a slight "sh" sound in words starting with "str," but this is not the standard pronunciation.
* Casual speech: People might pronounce words in a more casual or relaxed way, which could make it sound like "shtreet."
* Misinterpretation: Sometimes, people might simply be misinterpreting the way others pronounce "street" due to individual variations in speech.
In conclusion, the correct pronunciation of "street" is with a clear "str" sound, and it's not typical for people to pronounce it as "shtreet."
