A Sustained Vowel versus Connected Speech as a Measurement Target
The seed paper recorded both reading aloud and sustained isolated vowels, and names isolated-vowels-only as a limitation of its formant work. A held vowel is steady and easy to measure but unlike anything a person says; connected speech is realistic but its vowels are shortened and pulled toward their neighbours. The trade is measurement precision against ecological validity, and it is the cleanest case in the path of a design choice bounding a conclusion.
