Taylor Swift has changed geographic environments, speaking communities, and singing communities throughout her career, inviting question into changes in her voice acoustics. Capitalizing on the availability of interviews and multiple song recordings, we tracked changes in vowel formant trajectories and other vocal properties from different points in her life to see how her voice might have been influenced by these changes in community (e.g switching from country to pop style, moving from Philadelphia to Nashville). Comparing vowel space from 2012 to 2019, we observe higher tongue position (lower frequency F1) for numerous vowels, especially for /eɪ/ and /aʊ/. Rounding for /ɔ/ was reduced, and /æ/ was pronounced farther back in the mouth. We also observed reduced distinction between the varieties of /ɑɪ/ before voiced and voiceless consonants (e.g., ride versus write), as well as greater front-back movement for /u/. Studio re-recordings show remarkable consistency of word timing and intensity. Conversely, Swift’s live singing voice includes some variation from the recording, including fewer silences between words. Live versions feature extended duration for words that are emphasized for emotion, and/or ends of phrases, compensated by shorter durations for other segments so that the overall song length was very consistent.
