Proto-conversation starts early. Pre-linguistic infants engage in dynamic interaction with their carers, and are also affected by ambient language. By about 6 months baby is babbling, a key stage in language development. (e.g. Pulvermuller, 2002; Oudeyer, 2006). Our experiments start at this stage, with simulated teacher and robot. The baby’s babble begins to be biased towards carers’ speech. Words and holophrases start to be segmented from a stream of phonemes, but without meaning.
Part 1 Procedural, pattern learning, without meaning, analogous to dorsal processing
ambient acoustic signal
categorical perception of phonemes canonical babbling
experience of teacher’s bias to perceived syllables syllable patterns
produce word without intent
Part 2 Explicit learning of word and holophrase meaning,
analogous to ventral stream
Outline of model: part 2, item learning with meaning
Words from teacher
word(s) from teacher
