Studying speech production has allowed the discovery of numerous patterns that hold within—and, at times, differ across—speaker groups (e.g., voice-onset-time as a cue for consonant voicing). However, such work rarely explores the variation and consistencies that might be observed within comparable numbers of productions from a single speaker. In fact, acoustic analyses of speech production most often survey relatively few observations from each speaker, where high participant numbers are required to offset limited by-speaker contributions. Therefore, previous research often addresses inter-speaker variation, but by nature disallows any meaningful exploration of variation/consistency across productions from a single speaker. In tandem with the Massive Auditory Lexical Decision (MALD) study [Tucker et al., Behav. Res. 51(3), 1187–1204 (2019)], the present work serves two purposes: (1) to analyze and describe speech stimuli comprising the MALD single-speaker corpus (26 793 English words and 9592 English pseudowords, roughly 6 h of recorded speech in total), and (2) to suggest the breadth of work possible using such a corpus. As examples of the latter, analyses are provided to compare and contrast acoustic characteristics associated with varying degrees of lexical stress, and to explore the vowel space as realized in words versus pseudowords.
