Effects of testosterone on speech production and perception: Linking hormone levels in males to vocal cues and female voice attractiveness ratings.

This study sets out to investigate the potential effect of males' testosterone level on speech production and speech perception. Regarding speech production, we investigate intra- and inter-individual variation in mean fundamental frequency (f) and formant frequencies and highlight the potential interacting effect of another hormone, i.e.

The Effect of Fundamental Frequency on Gender Perception in Prepubertal Children: Insights from the LoKiS Database.

This study examines the impact of fundamental frequency on gender perception in prepubertal children in the LoKiS database - a longitudinal project collecting and analyzing recordings of approximately 60 German primary school children aged 6 to 10years. Spontaneous and content-controlled audio recordings were collected in two German primary schools. Three distinct listening experiments with over 100 listeners were conducted.

The Acoustic and Perceptual Correlates of Gender in Children's Voices.

Purpose: This study investigates the perceptual and acoustic correlates of gender in prepubertal voices. The study is part of a longitudinal project analyzing recordings of circa 60 German primary school children from the first to fourth grades (6- to 10-year-olds).

Method: Spontaneous and content-controlled audio recordings were made of 62 first-grade children (29 girls, 33 boys; age: 6- to 7-year-olds) from two German primary schools.

Gender identity is indexed and perceived in speech.

This study investigates a possible relationship between perceived and self-ascribed gender identity and the respective acoustic correlates in a group of young heterosexual adult speakers. For the production study, a sample of 37 German speaking subjects (20 males, 17 females) filled out a questionnaire to assess their self-ascribed masculinity/femininity on two scales. A range of acoustic parameters (acoustic vowel space size, fundamental frequency, sibilant spectral characteristics) were measured in speech collected from a picture describing task.

Investigating the common set of acoustic parameters in sexual orientation groups: A voice averaging approach.

While the perception of sexual orientation in voices often relies on stereotypes, it is unclear whether speech stereotypes and accurate perceptions of sexual orientation are each based on acoustic cues common to speakers of a given group. We ask if the stereotypical belief, that members of the same sexual orientation group share similar acoustic patterns, is accurate to some degree. To address this issue, we are the first to use a novel voice morphing technique to create voice averages from voices that represent extremes of a given sexual orientation group either in terms of actual or perceived sexual orientation.

"Do I Sound Straight?": Acoustic Correlates of Actual and Perceived Sexual Orientation and Masculinity/Femininity in Men's Speech.

Purpose: This study aims to give an integrative answer on which speech stereotypes exist toward German gay and straight men, whether and how acoustic correlates of actual and perceived sexual orientation are connected, and how this relates to masculinity/femininity. Hence, it tests speech stereotype accuracy in the context of sexual orientation.

Method: Twenty-five gay and 26 straight German speakers provided data for a fine-grained psychological self-assessment (e.

Acoustic correlates of sexual orientation and gender-role self-concept in women's speech.

Compared to studies of male speakers, relatively few studies have investigated acoustic correlates of sexual orientation in women. The present investigation focuses on shedding more light on intra-group variability in lesbians and straight women by using a fine-grained analysis of sexual orientation and collecting data on psychological characteristics (e.g.

Speaker perception.

While humans use their voice mainly for communicating information about the world, paralinguistic cues in the voice signal convey rich dynamic information about a speaker's arousal and emotional state, and extralinguistic cues reflect more stable speaker characteristics including identity, biological sex and social gender, socioeconomic or regional background, and age. Here we review the anatomical and physiological bases for individual differences in the human voice, before discussing how recent methodological progress in voice morphing and voice synthesis has promoted research on current theoretical issues, such as how voices are mentally represented in the human brain. Special attention is dedicated to the distinction between the recognition of familiar and unfamiliar speakers, in everyday situations or in the forensic context, and on the processes and representational changes that accompany the learning of new voices.

Auditory adaptation in voice perception.

Perceptual aftereffects following adaptation to simple stimulus attributes (e.g., motion, color) have been studied for hundreds of years.

Compensatory articulations in a case of congenital aglossia.

This paper examines the articulatory and phonatory strategies used by a German female born without a tongue. Analysis concentrates on the phonetic correlates of dorsal plosives. The speaker uses two main strategies.
