Summary: Infants show a preference for infant-directed speech (IDS), which benefits their language acquisition. This study investigated the specific frequency band that triggers increased electrophysiological tracking of IDS compared to adult-directed speech (ADS). The results showed that infants track speech in both IDS and ADS at the rates of syllables and prosodic stress. However, the increased tracking in IDS mainly comes from enhanced prosodic stress. This suggests that neural tracking is sensitive to parents' speech adaptations during natural interactions and supports higher-level processes like word segmentation.

Summary: This study aimed to explore the linguistic and pragmatic features of infant-directed speech (IDS) during mother-infant interactions at 3 months of age. The results showed few differences in IDS linguistic characteristics between preterm and full-term infants. Additionally, full-term mothers adjusted their IDS pragmatic features based on the quality of co-regulation, while preterm mothers did not. Parenting stress was associated with specific linguistic IDS features regardless of birth status.

Summary: This study aimed to investigate emotional and prosodic components of Infant-directed speech (IDS) longitudinally during a child's first year of life by analyzing children's responses to different prosodic trends used by mothers. The results showed that IDS production varies with the child's age, with higher intensity at only nine months, as seen in the results related to elocution velocity. The maternal verbal sensitivity and ability to tune into the child's affective states, especially at nine months, can predict the child's understanding of future language.

Summary: Social interactions are crucial for healthy brain development, and contingent timed vocal responses play a key role in early language development. Infants at 6 months show a significant positive ERP response to contingent vocalisations, while infants at 9 months show a negative ERP response to contingent speech from the mother.

Summary: Motherese, or emotional infant directed speech (IDS), is a specific form of language used by parents to communicate with their infants. This study found that most pregnant women speak to their fetuses and that motherese prosody can be detected through both annotation and automatic analysis methods. However, maternal anxiety or depression did not seem to have an impact on the use of motherese, but higher depression scores were associated with less talking to the fetus during recording.

Summary: Infant-directed singing has unique acoustic characteristics that allow infants to respond to the rhythms in the caregiver's voice. This study examined neural and movement responses to maternal singing in 7-month-old infants and found that these responses were related to linguistic development. The acoustic features and rhythmic movements of infant-directed singing were found to influence infant's vocabulary at 20 months.

Summary: Child-directed speech is found in many languages around the world, but the differences in its implementation and cultural support have raised questions about its universality. This study found that adult participants from different language/cultural communities have varying abilities to discriminate child-directed speech, and there are complex relationships between affect expression and child-directed speech across languages.

Summary: Maternal depressive symptoms may have an impact on children's language skills, with child-directed speech as a potential pathway. However, the current research on the relationship between maternal depressive symptoms and the complexity of child-directed speech is limited and further investigation is needed.

Summary: The study reveals that dogs show preference towards speech directed at them, especially when the speech is more prosodic. Different types of speech stimuli can influence dogs' choice preference, with dogs showing a preference for target objects associated with generalized dog-directed speech. Additionally, the results suggest that dogs exhibit neural specialization when processing different types of speech stimuli.

Summary: The hypothesis that parents help infants learn phonetic categories by speaking to them in infant-directed speech (IDS) rather than adult-directed speech (ADS) has been tested using Japanese adult speech data. The separability and robustness of vowel category learning were examined, finding that hyperarticulated speech in read speech (RS) improved separability, while increased between-speaker variability in ADS enhanced robustness for some algorithms. However, these effects were not observed in IDS, leading to the discussion of the role of machine learning algorithms in testing hypotheses about the functional role of IDS.

Summary: Research on EEG coherence values during spoken and imagined speech showed higher coherence levels during real verbalization, especially in the gamma-2 rhythm frequencies. Specific spatial coherence patterns in the left cerebral hemisphere were formed during imagined speech at gamma-2 frequencies. Machine learning and neural network classification demonstrated significant similarity between spatial coherent patterns of spoken and inner speech, with potential application in Brain-computer interfaces (BCIs).

Summary: The study found that providing expert-annotated prosodic breaks may not uniformly help all segmentation models, with sub-lexical algorithms benefitting the most. Errors in the detection of boundaries from automatically derived prosodic information lead to smaller positive effects, and even negative effects for some algorithms when acoustic cues known to be sensitive to infants are used in the analysis.

Summary: Perception of prosody is crucial for spoken language communication, including comprehension, pragmatics, and phonological awareness. This study introduces the Test of Prosody via Syllable Emphasis (TOPsy) as a phenotyping tool to measure lexical stress sensitivity. The test demonstrates excellent reliability and predictive validity, suggesting its potential for large-scale investigations of prosody and reading.

Summary: New interdisciplinary research into genetic influences on musicality raises ethical and social issues. The historical intersection of music cognition and eugenics highlights the importance of carefully considering the risks and benefits of these studies. Experts from various disciplines have come together to provide guidance on ethically and socially responsible conduct in the field of musicality genetics research.

Summary: Music engagement is a powerful experience that often starts early in life and has moderate heritability in adults. This study focuses on genetic and environmental influences on music listening and instrument playing in 9-10-year-old children, finding that both measures are primarily influenced by shared environment. Instrument exposure is associated with language skills and executive functions more strongly than music listening, visual arts, or soccer engagement.

Summary: This study focuses on the impact of musicality on language acquisition and development, proposing the Musical Abilities, Pleiotropy, Language, and Environment (MAPLE) framework. The framework suggests that musical and language-related abilities may share genetic architecture and neural endophenotypes, and be influenced by genetic pleiotropy and enriched environments.
