“…Results showed stronger speaker evidence with formant trajectories than mid-vowel measurements. Similar results were reported for Czech monophthongs taken from different consonantal contexts, and from stressed and unstressed syllables (Fejlovà et al 2013). This study did not differentiate between conditions with and conditions without dynamic formant information, but when the order of the polynomial fit was increased from linear to cubic, speaker classification performance improved.…”

“…The majority of acoustic-phonetic studies undertaken so far used read speech to assess the usefulness of dynamic formant representations for speaker classification (e.g. Ingram et al 1996;McDougall 2004McDougall , 2006McDougall and Nolan 2007;Morrison 2008Morrison , 2009aThaitechawat and Foulkes 2011;Fejlovà et al 2013;Zuo and Mok 2015). These representations generally included both static and dynamic formant information.…”

“…Even though earlier research shows an important contribution of dynamic formant representations to speaker classification and discrimination (e.g. Ingram et al 1996;McDougall 2004McDougall , 2006McDougall and Nolan 2007;Morrison 2008Morrison , 2009aThaitechawat and Foulkes 2011;Fejlovà et al 2013;Zuo and Mok 2015), this body of work has some limitations. First, most vocalic materials studied so far were diphthongs, as a result of which the usefulness of formant dynamics for speaker classification from monophthongs remains understudied.…”

“…The literature on vowel-inherent spectral change, however, would suggest that also monophthongs may be expected to contain speaker-dependent differences in their dynamics. There are a few studies that included such vowels (Fejlovà et al 2013;Rose 2015;Hughes et al 2016;Wang et al 2019), but results varied (details in section 1.1).…”

The relative contributions of static and dynamic formant representations to speaker-specificity were investigated in conversational speech and in two vowels varying in inherent spectral change. Using polynomial fits, the contribution of dynamic formant coefficients to speaker-specificity relative to that of the formant intercept was investigated in the diphthongal vowel [ei] taken from English and Dutch conversational speech. The [ei] tokens were sampled from various linguistic contexts and analysed in an LR approach. Results show that formant dynamics contain speaker-specific information in conversational speech even though the high contextual variation seems to reduce its effect relative to that reported by earlier work. Vowels differ in inherent dynamicity and therefore, the added value of dynamic formant information to speaker-specificity was also compared between vowels differing in inherent spectral change. Using Dutch data, the contribution of formant dynamics to speaker-specificity was compared between [ei] and [a?] tokens produced by the same speakers. Formant dynamics in conversational speech only contributed to speaker-specificity in the diphthong [ei], not in the monophthong [a?].

“…As in Dutch (see Van den Heuvel, 1996), the vowel [aː] was found to contain more speaker-dependent information than [i, u] (Schindler & Draxler, 2013). In Czech, the vowel [iː] was found to pattern more with [aː] than [u] (Fejlová et al, 2013). Finally, various diphthongs were also found to differ in the speaker-specific information they carry (e.g.…”

The acoustic-phonetic characteristics of speech sounds are influenced by their linguistic position in the syllable or sentence. Because of acoustic-phonetic differences between different speech sounds, sounds vary in the amount of speaker information they contain. However, do spectral and durational differences between realizations of the same sound that were sampled from different linguistic positions also impact speaker information? We investigated speaker discrimination in [−focus] versus [+focus] word realizations. Twenty-one Dutch listeners participated in a same-different task, using stimuli varying in focus, vowel ([aː], [u]), and word context ([ɦ_k], [v_t]), spoken by 11 different speakers. Results showed that an effect of focus on speaker-dependent information was present, but limited to words containing [u]. Moreover, performance on [u] words was influenced by (interactions of) word context and trial type (same-vs. different-speaker). Context-dependent changes in a speech sound’s acoustics may affect its speaker-dependent information, albeit under specific conditions only.
