Seminar at Speech, Music and Hearing:

Imitating adult speech: an infant´s motivation

Gopal Ananthakrishnan


This talk touches upon two aspects of speech acquisition by infants which are often assumed to be intrinsic or innate knowledge, namely number of degrees of freedom in the articulatory parameters and the acoustic correlates that find the correspondence between adult speech and the speech produced by the infant.The first part of the talk tries to motivate how the infant explores several acoustic correlates as well as different number of degrees of articulatory freedom. Being able to distinguish the different vowels in the vowel space of the certain language is a strong motivation for choosing both, a certain number of independent articulatory parameters, as well as a certain scheme of acoustic normalization between adult and child speech. The second part details a proposed model which tries to learn the acoustic normalization scheme using topological mapping between adult utterances and the babbling produced by the infants.
