Measures of vowel overlap explore the acoustic similarity between proposed and existing vowel categories. They typically compare F1 and F2, and sometimes duration. In the present study, we investigate four methods of quantifying vowel overlap: the spectral overlap assessment metric (Wassink,...

The overlap of vowel categories is a fairly common linguistic phenomenon. But, it can be difficult to judge whether two supposedly distinct vowel categories have merged or not. One tool that a researcher may use is a quantification of the overlap based on acoustic properties of recorded vowel...

Poster for the paper "A comparison of input types to a deep neural network-based forced aligner," presented at Interspeech 2018. Typo in alignment matrix (O[2,2] referenced O[1,2] instead of O[1,1]) updated on June 4, 2019. PAPER ABSTRACT: The present paper investigates the effect of different...

Forced alignment is increasingly used in phonetics to automatically produce boundaries between words and phones. These boundaries can have significant errors and are often only placed at some predetermined time interval, like every 10 ms. We discuss some potential remedies to these difficulties...

The present study uses a measure of the dispersion of density throughout the vowel space—called the vowel dispersion index—to assess speech patterns in head-and-neck cancer patients. The vowel dispersion index is based on calculating the total variation of the density values in Story and Bunton’s...

In the present study, I propose an acoustically-based alternative to phonological neighborhood density. Phonological neighborhood density has been used in many studies as an approximate quantification of lexical competition during spoken word recognition. However, phonological neighborhood...

A number of speech perception studies have been carried out to investigate how we process audio signals containing real words. However, comparatively fewer studies have been conducted looking at how listeners process audio signals containing phonotactically legal pseudowords. Some traditional...

Research on speech perception and lexical access often uses the activation and competition metaphor to describe the process of spoken word recognition. One way of expressing competition associated with a given word is its phonological neighborhood density, which is a calculation of similarity....

Tucker, Benjamin V., Porretta, Vincent, Mukai, Yoichi

Spontaneous, casual speech is highly variable, in part due to reduction processes. Listeners handle these reductions in everyday communication; however, these forms present challenges for models of speech perception and lexical processing. Previous research has found that reaction times to...
