In this preliminary study, we examine the F0 declination line (F0DL) between the age of 9 months, when the child still babbles, and the age of 30 months when a first language, with some longer and complex sentences, is already acquired. An instrumental analysis (Pitch detection, F0 curves) was conducted. We computed a linear regression on all detected F0 values and we tested statistically its significance. The first results show that both situation of communication (solitary vs interaction with an adult) and age influence the presence and use of FoDL. Its physiological and phonological aspects in communication and language development are discussed.
