The topic of this dissertation is the development of consonant production by children in the early lexical period. A unique corpus is used including monthly collected speech from 30 children acquiring Dutch (age: 0;6 - 2;0) in interaction with their primary caregivers. This corpus is unique in the sense that the number of the children as well as the amount of longitudinally collected speech per child is larger than any other corpus of children's spontaneous speech. Moreover, the corpus also includes the primary caregiver's speech directed to each child at each month
Numerous studies have attempted to describe consonant acquisition. Yet, important reservations can be formulated concerning the applied methodology. Nonetheless, a solid treatment of empirical data is the basis for charting developmental paths and discussing language acquisition processes. This thesis makes a fundamental contribution to the field by pinpointing methodological limitations and providing new data and procedural guidelines for increasing the reliability of widely used language measures, such as the consonant inventory
Implementation of these guidelines resulted in consonant inventories established for three different word positions: word-initial, word-medial, and word-final. Plosives, nasals, labials, and coronals occur in most inventories of Dutch-speaking children. Near the end of the second year of life, variation is seen regarding the acquisition and incidence of other manner and place classes of consonants. A comparison of the present results with those reported on other languages reveals cross-linguistic similarities as well as cross-linguistic differences, suggesting an important role of the input language on consonant development
Then, the impact of two factors of the input is investigated: input frequency (IF) and functional load (FL). The corpus study reveals significant correlations between IF/FL and acquisition order: the higher the IF and the higher the FL of a consonant, the earlier the consonant appears in the child's speech. In a partial rank correlation, FL is assigned as the determinant factor, while IF has only a small, non-significant contribution. This finding suggests that the discriminating function of consonants in minimal pairs of words in the child-directed speech has a decisive influence on the age at which consonants are acquired
