“…Importantly, within-vowel-category dispersion was higher in speech than in song. This is consistent with the idea that singing compared to speaking provides more stability in the vowel domain, in duration, but also in pitch and formant structure [11,12]. At the same time, vowel space expansion appeared overall smaller in song than in speech, mainly due to more closed articulation of /a/ in singing.…”

When adults talk to infants, they dramatically change the prosodic and acoustic structure of speech. Recently, new insights have been gained on those changes, especially on the vocalic and temporal structure of speech which are described as being more variable than in adult conversations. In the present contribution, we examine formant and fundamental frequency characteristics of different infant-directed registers, notably infant-directed speech and singing, the latter not being investigated so far. We present data from 14 German-speaking mothers singing a playsong and reading a story to their 6 months old infants, or to the experimenter. Infant-and infantabsent versions of speech and song were compared on the formant characteristics of the primary vowel triangle (/i, a, u/) and on general fundamental frequency changes. Our results show that vowel space did not differ in infant-and infantabsent versions of speech and song. However, vowel dispersion, i.e., formant variability, was higher in both infantdirected song and speech than in infant-absent versions. Consistent with previous findings, f0 was higher in infantthan infant-absent versions of speech and song, with song showing generally higher f0. These results are discussed in light of current approaches to the variability of infant-directed registers, and their attractiveness to infants.

“…As in speech, infants prefer ID over AD versions of songs [10]. On the other hand, singing generally differs from speaking in that sung vowels usually display more stable f0 contours, and that they are longer and less variable in duration [11,12]. ID singing also features higher metrical regularity ("beat structure") than ID speech [13].…”

“…If acoustic focus and/or a slow speaking rate were necessary and sufficient for a mature segmentation response, the song familiarization should have elicited a group-level negative-going response or enabled more children to display this response. Thus, the observed positivity in the song familiarization could reflect additional challenges segmenting words from songs, such as the atypical acoustic signal of sung compared to spoken language [41,42]; cf. [43], or the increased risk of mis-segmentations from songs [44,45,123].…”

“…Nevertheless, it is not trivial that infants pick up linguistic information from songs. Firstly, infants' speech-honed language-learning skills may not be successful when applied to the acoustic signal of songs: lyrics sung to a melody are produced with different acoustic features than regular speech [41], including a more compressed and less consistently produced acoustic vowel space [42], cf. [43].…”

Infants Segment Words from Songs—An EEG Study

Children’s songs are omnipresent and highly attractive stimuli in infants’ input. Previous work suggests that infants process linguistic–phonetic information from simplified sung melodies. The present study investigated whether infants learn words from ecologically valid children’s songs. Testing 40 Dutch-learning 10-month-olds in a familiarization-then-test electroencephalography (EEG) paradigm, this study asked whether infants can segment repeated target words embedded in songs during familiarization and subsequently recognize those words in continuous speech in the test phase. To replicate previous speech work and compare segmentation across modalities, infants participated in both song and speech sessions. Results showed a positive event-related potential (ERP) familiarity effect to the final compared to the first target occurrences during both song and speech familiarization. No evidence was found for word recognition in the test phase following either song or speech. Comparisons across the stimuli of the present and a comparable previous study suggested that acoustic prominence and speech rate may have contributed to the polarity of the ERP familiarity effect and its absence in the test phase. Overall, the present study provides evidence that 10-month-old infants can segment words embedded in songs, and it raises questions about the acoustic and other factors that enable or hinder infant word segmentation from songs and speech.

“…The melodic function is another mechanism that allows speech fluency improvement based on decreased speech motor control dependence on the internal model. Prosody is a resource of human expression that aims to provide more efficient and appropriate communication from the transmission of paralinguistic information such as tone, intonation, stress, and length (8,9) . When a predetermined melody or speech rhythm is used, clues of length, frequency, and intensity are available and used by the speech motor control system, facilitating fluency.…”

Purpose: The aim of this study was to compare the speech performance of fluent speakers and individuals who stutter during spontaneous speech, automatic speech, and singing. Methods: The study sample was composed of 34 adults, 17 individuals who stutter and 17 fluent controls, matched for gender and age. The speech performance of participants was compared by means of three tasks: monologue, automatic speech, and singing. The following aspects were assessed: total number of common disruptions and total number of stuttering-like disruptions. Results: Statistically significant difference was observed only for the monologue task in both intra-and inter-group comparisons. Conclusion: The outcomes of this study indicate that tasks of higher motor and melodic complexities, such as the monologue task, negatively affect the speech fluency of both fluent speakers and individuals who stutter. RESUMOObjetivo: O objetivo do estudo foi comparar a performance de fala do indivíduo com gagueira e do indivíduo fluente em tarefa de fala espontânea, tarefa de fala automática e a tarefa de canto. Método: Participaram deste estudo 34 adultos, 17 com gagueira e 17 fluentes, pareados por gênero e idade. O estudo comparou o desempenho dos participantes em três tarefas de fala: monólogo, fala automática e canto. Foi analisado o número total de rupturas comuns e gagas. Resultados: A tarefa de monólogo foi a única que apresentou diferenças estatisticamente significativas, tanto nas comparações intragrupos quanto nas comparações intergrupos. Conclusão: O estudo mostrou que tarefas de maior complexidade motora e melódica, como a tarefa de monólogo, prejudica a fluência da fala, tanto em indivíduos com gagueira quanto em indivíduos fluentes.Costa et al.
