Reintroducing and testing the Probabilistic Sliding Template Model of vowel perception
Normalization of the speech signal onto comparatively invariant phonetic representations is critical to speech perception. Assumptions about this process also play a central role in phonetics and phonology. Yet, despite the importance of these assumptions, popular normalization accounts continue to incorrectly assume that the relevant normalization parameters are “known” – for example, because the researcher can estimate them from a fully balance…
Normalization, essentialization, and the erasure of social and linguistic variation
Perceptual normalization is categorical (phonemic) and gradient (phonetic) • Normalization algorithms are mathematical implementations of speech perception. • Phonetic normalization algorithms should be tested against listener judgments. • Viewing normalization as erasing anatomy essentializes linguistic variation. • Accurate speech variation documentation needs theoretically grounded normalization. Linguists investigating the phonetic properties…
Learning a language with vowelless words
Vowelless words are exceptionally typologically rare, though they are found in some languages, such as Tashlhiyt (e.g., fkt 'give it'). The current study tests whether lexicons containing tri-segmental (CCC) vowelless words are more difficult to acquire than lexicons not containing vowelless words by adult English speakers from brief auditory exposure. The role of acoustic-phonetic form on learning these typologically rare word forms is also expl…
Inaccurate but predictable
Research suggests human listeners are not very accurate in assessing the size of adults from their speech, though they appear to be consistent in their judgments across listeners. Two experiments were conducted to investigate the importance of the higher formants for providing consistent height judgments, how consistent these height judgments are across replications, and the role of f0 and social knowledge in maintaining the stability of apparent…
Perceptual identification of oral and nasalized vowels across American English and British English listeners and TTS voices
Nasal coarticulation is when the lowering of the velum for a nasal consonant co-occurs with the production of an adjacent vowel, causing the vowel to become (at least partially) nasalized. In the case of anticipatory nasal coarticulation, enhanced coarticulatory magnitude on the vowel facilitates the identification of an upcoming nasal coda consonant. However, nasalization also affects the acoustic properties of the vowel, including formant frequ…
Early childhood predictors of early school‐age academic skills and resilience among children living in poverty
This longitudinal study of low‐income families tested neighborhood‐, family‐, and child‐centered promotive factors in early childhood, responses to an early family intervention, and their interactions as predictors of school‐entry levels of and early school‐age gains in academic skills. Using a racially‐diverse, low‐income sample ( n = 527) from a randomized controlled trial of the Family Check‐Up (FCU) intervention and Bayesian multilevel regres…
Fast Track
Fast Track is a formant tracker implemented in Praat that attempts to automatically select the best analysis from a set of candidates. The best track is selected by modeling smooth formant contours across the entirety of the sound, providing the researcher with rich information about static and dynamic formant properties. Fast Track returns text files containing acoustic information (formant frequencies, formant bandwidths, fundamental frequency,…
Perceptual validation of vowel normalization methods for variationist research
The evaluation of normalization methods sometimes focuses on the maximization of vowel-space similarity. This focus can lead to the adoption of methods that erase legitimate phonetic variation from our data, that is, overnormalization. First, a production corpus is presented that highlights three types of variation in formant patterns: uniform scaling, nonuniform scaling, and centralization. Then the results of two perceptual experiments are pres…
Vowel normalization as perceptual constancy
This study investigates how listeners associate acoustically different vowels with a single linguistic vowel quality. Listeners were asked to identify vowel sounds as /æ/ or /ʌ/ and to indicate the size of the speaker that produced them. Results indicate that perceived vowel quality trades off with the perception of speaker size: different vowels can sound the same, and the same vowel can sound different when a different speaker is perceived. The…
Listeners respond to phoneme-specific spectral information when assessing speaker size from speech
