A dataset containing formant measurements from the midpoints of 564 vowel tokens. These came from generated nonce words. This dataset is relatively clean and can be used for vowel formant example data.
vowels
A data frame with 564 rows and 12 variables:
a unique identifier for each vowel token
the start time for that vowel
the end time for that vowel
the time where formants were extracted
the F1 measurement
the F2 measurement
the F3 measurement
the F4 measurement
the generated nonce word I read
the consonant(s) before the vowel (if any)
the vowel class, in Wells' Lexical Sets
the consonant(s) after the vowel
I generated 246 nonce words of the form (C)CVC(C) with the following sounds:
Onsets: /t/, /d/, /s/, /z/, n/, /h/, / /, /st/, /sn/
Vowels: /i/, /ɪ/, /eɪ/, /ɛ/, /æ/, /a/, /ɔ/, /oʊ/, /ʊ/, /u/
Codas: /d/, /z/, /dz/.
Generally, only coronals were used. Clusters were okay. Codas were only obstruents. All American English vowels were used. Not the most scientific dataset, but sufficient for my purposes.
Every combination of these levels was generated and repeated three times. The resulting list was sorted randomly. I read them in a quiet environment, manually aligned them, extracted formants using a Praat script (4 formants at 4500 Hz), and filtered out the bad measurements.
The result is a pretty clean dataset showing my vowel formant trajectories, in the environment of a coronal consonant.
The intended purpose of this data is so that I can quickly have a nice sample at my disposal when illustrating R functions. However, you may use this dataset however you please.
