This study is based primarily on a new longitudinal corpus from E, a typically developing monolingual learner of English with no history of hearing problems or language delays. E has one sibling, a brother who is two years and five months older and who also exhibited normal phonological development. E’s mother is a native speaker of American English. E’s father is a native speaker of Turkish, but fluent in English; his slight Turkish accent is unlikely to have been a factor in E’s phonological patterns. During the course of language development, E was raised in a monolingual English-speaking environment. He was exposed to minimal amounts of Turkish but was virtually never addressed directly in this language. As of age 2;7, due to his sibling’s entry into a Spanish immersion school program, E began to be exposed to some Spanish, including the word hola, but not by native Spanish speakers.
The data from E were gathered in a naturalistic, diary setting primarily by his mother, a trained phonologist. E’s father, also a phonologist, participated in the data collection as well. Data collection was performed as often as possible, during unstructured sessions and regular family activities. The period of data gathering spans E’s ages 0;06.09 to 3;09.29, with most of the data collected prior to the last year of the study. Between ages 0;06.09 and 2;09.09, a span that corresponds to E’s phonological development peak (i.e. during which most aspects of the target grammar were acquired), a total of 3,267 words (distributed over 1,713 utterances) were transcribed phonetically. An additional 113 words were transcribed over the last year of the study, during which E’s mother was attending mainly to the development of /l/.
