“…The method used in this survey is adapted from the works of Johnson et al (2020), , and Lee & Kreiman (2022) on analyzing the voice-quality-related parameters. All analyses were carried out using R version 4.0.4 (R Core Team, 2021)…”

“…Breaking down the data sets into different components enables the researcher to better identify and explain the internal structure of the data-and thus find the similarities and differences in the voices of bilinguals. In PCA, since some correlation was expected between the measured parameters, oblique rotation was implemented to simplify the structure of the data (Johnson et al, 2020;Y. Lee & Kreiman, 2022).…”

Many individuals around the world speak two or more than two languages. This phenomenon adds a fascinating dimension of variability to speech, both in perception and production. But do bilinguals change their voice when they switch from one language to the other? It is typically assumed that while some aspects of the speech signal vary for linguistic reasons, some indexical features remain unchanged across languages. Yet little is known about the influence of language on within- and between-speaker vocal variability. The present study investigated how acoustic parameters of voice quality are structured in two languages of a bilingual speaker and to what extent such features may vary between bilingual speakers. For this purpose, speech samples of 10 simultaneous Sorani Kurdish-Persian bilingual speakers were acoustically analyzed. Following a psychoacoustic model proposed by Kreiman (2014) and using a series of principal component analyses, we found that Sorani Kurdish-Persian bilingual speakers followed a similar acoustic pattern in their two different languages, suggesting that each speaker has a unique voice but uses the same voice parameters when switching from one language to the other.

“…With PCA, the most variance of the data is accounted for by the first component, and each subsequent component accounts for a lesser variance. This method was particularly necessary for the voice quality measures as they are highly correlated with one another, and a similar approach was used in previous studies of voice quality [ 40 , 47 ]. Only those parameters related to the vocal folds directly (i.e., rate and manner of vocal fold vibration; the variables belonging to the “voice” type in Table 3 ) were thus included in PCAs.…”

“…In contrast, they have different segmental and prosodic characteristics from read speech [ 38 ], and one can find some speech characteristics more easily in spontaneous speech, such as connected speech processes, phonetic reduction [ 39 ], and speech style adaptations depending on the needs of the situation (e.g., hyperarticulation). We may be able to find acoustic variability (e.g., variability in f0) that would not be found in read speech [ 40 ]. We thus devised a new method for eliciting spontaneous speech from subjects while they played the role of a customer service employee talking to a customer, and this method controlled for the lexical items and syntactic structures of their utterances.…”

Acoustic correlates of perceived personality from Korean utterances in a formal communicative setting

The aim of the present study was to find acoustic correlates of perceived personality from the speech produced in a formal communicative setting–that of Korean customer service employees in particular. This work extended previous research on voice personality impressions to a different sociocultural and linguistic context in which speakers are expected to speak politely in a formal register. To use naturally produced speech rather than read speech, we devised a new method that successfully elicited spontaneous speech from speakers who were role-playing as customer service employees, while controlling for the words and sentence structures they used. We then examined a wide range of acoustic properties in the utterances, including voice quality and global acoustic and segmental properties using Principal Component Analysis. Subjects of the personality rating task listened to the utterances and rated perceived personality in terms of the Big-Five personality traits. While replicating some previous findings, we discovered several acoustic variables that exclusively accounted for the personality judgments of female speakers; a more modal voice quality increased perceived conscientiousness and neuroticism, and less dispersed formants reflecting a larger body size increased the perceived levels of extraversion and openness. These biases in personality perception likely reflect gender and occupation-related stereotypes that exist in South Korea. Our findings can also serve as a basis for developing and evaluating synthetic speech for Voice Assistant applications in future studies.

“…Substantial talker differences have been found in the production of English vowels (e.g., Hillenbrand et al, 1995;Johnson et al, 1993;Peterson & Barney, 1952) and consonants (e.g., Allen et al, 2003;Newman et al, 2001;Theodore et al, 2009;Westbury et al, 1998). Talkers also differ from one another in voice production, including habitual pitch (Atkinson, 1976;Stone & Rainey, 1991) and voice quality (Lee et al, 2019;2022;Pierce et al, 2021). Finally, talker differences exist in suprasegmental aspects of speech such as speaking rate (Tsao et al, 2006;Jacewicz et al, 2009) and relative duration of voiced and voiceless segments, generally referred to as speech "rhythm" (Leeman et al, 2014;Wiget et al, 2010).…”

Purpose: Previous work has shown that judgments of emotion differ between clear and conversational speech, particularly for perceived anger. The current study examines talker differences in perceived emotion for a database of talkers producing clear and conversational speech. Method: A database of 41 talkers was used to assess talker differences in six emotion categories (“Anger”, “Fear”, “Disgust”, “Happiness”, “Sadness”, and “Neutral”). Twenty-six healthy young adult listeners rated perceived emotion in 14 emotionally-neutral sentences produced in clear and conversational styles by all talkers in the database. Generalized linear mixed-effects modeling was utilized to examine talker differences in all six emotion categories. Results: There was a significant effect of speaking style for all emotion categories, and substantial talker differences existed after controlling for speaking style in all categories. Additionally, many emotion categories, including anger, had significant talker x style interactions. Perceived anger was significantly higher in clear speech compared to conversational speech for 85% of the talkers.Conclusions: While there is a large speaking style effect for perceived anger, the magnitude of the effect varies between talkers. The perception of negatively-valenced emotions in clear speech, including anger, may result in unintended interpersonal consequences for those utilizing clear speech as a communication facilitator. Further research is needed to examine potential acoustic sources of perceived anger in clear speech.
