nsp_vows: F1 and F2 from NSP hVd words
In kleinschmidt/nspvowels: Nationwide Speech Project hVd F1 and F2 values

A dataset containing hand-measured F1×F2 values from the "hVd" words in the Nationwide Speech project corpus. 48 American English talkers produced the 11 monophongal vowels of American English /i ɪ e ɛ æ ʌ u ʊ o ɔ ɑ/, 5 times each (with few exceptions). Talkers were students at Indiana University and are coded with demographic details (sex, age, and region of origin) and were selected to represent the six major dialect regions of American English (based on where they grew up, before attending IU).
