Infants listen for more phonetic detail in speech perception than in word-learning tasks
A recently developed technique is used to show that when they are required to pair words with objects, infants of 14 months fail to use the fine phonetic detail they detect in syllable discrimination tasks, and suggests a second reorganization in infants's use of phoneticdetail as they move from listening to syllables to learning words.
Acquisition of word-object associations by 14-month-old infants.
Strong evidence is provided that 14-month-old infants can rapidly learn arbitrary associations between words and objects, that this ability appears to develop at about 14 months of age, and that the Switch design is a useful method for assessing word--object learning in infancy.
PRIMIR: A Developmental Framework of Infant Speech Processing
A new, unified framework for accounting for divergent findings in infant speech perception is presented, including its underlying assumptions and overall architecture, and it is compared to existing frameworks to present core predictions of PRIMIR.
Infants' Ability to Learn Phonetically Similar Words: Effects of Age and Vocabulary Size
What do novice word learners know about the sound of words? Word-learning tasks suggest that young infants (14 months old) confuse similar-sounding words, whereas mispronunciation detection tasks
Phonemic and phonetic factors in adult cross-language speech perception.
Results suggest that the previously observed ontogenetic modification in the perception of non-native phonetic contrasts involves a change in processing strategies rather than a sensorineural loss.
Infant preference for both male and female infant-directed talk: a developmental study of attentional and affective responsiveness.
It was found that infants of both ages show greater attentional and affective responsiveness to IDT than to ADT when spoken by either a male or a female, suggesting that IDT may facilitate and maintain positive adult-infant interactions.

Discrimination of 2 German vowel contrasts was examined in English-learning infants of 6-8 and 10-12 months of age, revealing a shift from a language-general toward alanguage-specific pattern during the 1st year of life, however, that shift begins earlier in development for vowels than for consonants.
Two-month-old infants match phonetic information in lips and voice
Infants aged 4.5 months are able to match phonetic information in the face and voice (Kuhl & Meltzoff, 1982; Patterson & Werker, 1999); however, the ontogeny of this remarkable ability is not
