“…For most children, spoken language production begins close to the first birthday ( 24 , 25 ). And, during toddlerhood many children begin to produce word combinations and a rapid period of growth in spoken language production and processing occurs as children approach preschool age ( 26 , 27 ). Similarly, pro-social skills such as the inclination to help others emerge during toddlerhood and become routine behaviors as children develop social competence ( 28 , 29 ).…”

Explicating Child-Driven Patterns of Parent-Child Responsivity in Fragile Families: A Longitudinal Approach

It has been well-established that development occurs in the context of a transactional framework, with bidirectional parent-child interactions influencing both proximal and distal outcomes. In particular, child vocabulary development is sensitive to parenting qualities including warmth, sensitivity, and control as well as parental stimulation including language input and access to learning enrichment activities. Similarly, these parenting qualities are influenced by and influence children's development of pro-social behaviors. Given the foundational role of both language and pro-social skills for academic achievement and the establishment of healthy relationships across the lifespan, a comprehensive understanding of the magnitude, stability, and reciprocity of such interactions across childhood has the potential to better inform early intervention and prevention practices and highlight risk and resilience factors. This study investigated the concurrent and successive transactional relationships between child pro-social behavior, child emergent language, and parenting qualities within a large, longitudinal sample. This study utilized Waves 3, 4, and 5 of the Fragile Families and Child Well Being Study (FFCWBS), corresponding to focal child age 3, 5, and 9 years, respectively. A series of Structural Equation Modeling (SEM) with full-information likelihood (FIML) estimation (n = 3,422) including child prosocial behavior, receptive vocabulary, and supportive parenting behaviors was tested and compared. Our findings indicate significant, positive associations over time between child pro-social behavior and receptive vocabulary, and parenting quality across all three stages of early child development. The steady decline in magnitude of these associations over time highlights the importance of synergistic parent-child interactions in toddlerhood as an early opportunity to propel these developmental outcomes and supportive parenting behaviors. Patterns of change in child pro-social behavior skills and parenting qualities remained positive and relatively stable, while observed growth in child receptive vocabulary skills increased in magnitude over time. Additional investigation of indirect effects specified the role of receptive vocabulary, as well as the bolstering role of prosocial behavior, in eliciting responsive parenting qualities over time.

“…2.3.1 Articulation rate. Following our previous study (e.g., Tendera et al, 2019), the number of syllables in each utterance was divided by the duration between speech onset and offset to give articulation rate at each time point.…”

“…Ten utterances that met the selection criteria were coded in the original transcript to guide the extraction of samples from the audio record as discrete wav files corresponding to a single utterance (see Tendera et al, 2019;Wondershare Software). A noise reduction algorithm included in the Audacity Software was used to increase the signal-to-noise ratio (Mazzoni & Dannenberg, 2000).…”

A phenomenon called “repetition reduction” can increase articulation rate in adults by facilitating phonetic and motor processes, which indicates flexibility in the control of articulation rate. Young children, who speak much slower, may not have the same speech motor flexibility resulting in the absence of the repetition reduction effect. In this study, we tested whether spontaneous repetitions of young children are produced with a faster articulation rate than their original utterances. Twelve monolingual English-speaking children were observed at four time points between 2;0 and 3;0 years of age. A significant increase in articulation rate and syllable count was found using multilevel models for all utterances over the 1-year period. At each time point, however, the repeated utterances were produced significantly faster than the original utterances even though the content and syllable count differed minimally. Our findings conform to the pattern of adult studies suggesting that a “naturistic” form of repetition reduction is already present in the speech of children at 2;0 years. Although certain aspects of speech motor control are undergoing rapid development, existing motor capability at 2;0 already supports flexible changes in articulation rate including repetition reduction.

“…In this respect, the discussion surrounding issues of the fundamental frequency range of the voice and its average levels is highlighted by Freud et al (2018), Tendera et al (2019) and Ambarita and Mulaydi (2020), inter alia. Insights from this literature suggest that the most common values for the average fundamental frequency pitch of male speakers are around 110-115 Hz, while those of female speakers are approximately 190-210 Hz.…”

Literature has mainly analyzed the technical attributes of voice for enterprise technical applications, such as voice signature and speech recognition. This paper aims at identifying voice and speech attributes that reflect sentiment and affect (positively or negatively) customer satisfaction levels in voice interactions. The paper used method triangulation that utilizes multiple data sources to gain comprehensive understanding of the domain, including auditory observations, focus group interviews, customer survey, and a review of recent academic studies. The findings indicate that customer experience and satisfaction are influenced by the relative values of voice pitch between the CSR (customer service representative) and the customer. The major conclusion of the study suggests that voice fundamental pitch, speech rate, voice amplitude, and other communication parameters might deploy hidden power and affect service interaction's results. The study opens a new venue for research on social interaction adjustment from the CSR's perspective and from the customer's standpoint.
