Editing Vowel shift (section)

==== Northern California Vowel Shift ====
In Northern California, there is a chain vowel shift occurring. Short front vowels that used to be higher are shifting to lower vowel spaces in native Northern California speech acts involving the vowels /i/, /ɛ/ and /æ/. Additionally, Northern California speech acts are centralizing the sound that occurs in words such as boat (/oʊ/).<ref>{{Cite journal|last1=Kennedy|first1=R.|last2=Grama|first2=J.|date=2012-03-01|title=Chain Shifting and Centralization in California Vowels: An Acoustic Analysis|url=https://read.dukeupress.edu/american-speech/article/87/1/39-56/5933|journal=American Speech|language=en|volume=87|issue=1|pages=39–56|doi=10.1215/00031283-1599950|issn=0003-1283|url-access=subscription}}</ref> These shifts in vowel shortening and centralization, while not entirely unique to the region of Northern California natives, does represent the most obvious changes that are occurring within the area in regards to native speech acts.
