Step of the Research Data Analysis

3.4. Step of the Research

1. The writer observes all of the words which are produced by the subjects and writes it in a note while also recording their speeches with a recorder. 2. The writer lists all the words which have been collected, either from the note or the recorder and writes them in the form of phonetic transcription. 3. The writer then makes the comparison between two subjects and makes the utterances. 4. The writer separates them into 4 tables. The first part includes of the phonological processes of two subjects in acquiring language in the first month, and the second part includes of the phonological processes of two subjects in acquiring language two months after the first observation. 5. The writer divides all the words which are produced by the subjects through Ingram’s theory substitution, assimilation, and syllable structure process and classifies them into the appropriate process. 6. Then the writer divides the ability comparison between two subjects in producing the words.

3.5. Data Analysis

In analyzing the data, the writer first lists all of the words which are produced by the subjects. It is listed based of the month of the observation. The listing is done Universitas Sumatera Utara in order to help the writer analyzes and interprets more clearly the words which are produced by the subjects. Next, the word which has already been listed, are transcribed phonetically based on the two books that the writer used as the guidance in transcribing the words. Those two books are the one who is written by Ladefoged 1975, entitled ‘A Course in Phonetics’ and the other one is Indonesian book entitled ‘Fonetik’ written by Marsono 1989. When the writer is done with those steps above, the writer then makes the comparison between two subjects in acquiring language. From that comparison, then the writer can interpret and analyze the word production done by two years old Indonesian children through the theory of phonological process delivered by Ingram. The process is divided into three categories: substitution, assimilation, and syllable structure process. Those three categories are still divided more in several sub processes. Thus the writer needs to analyze clearly one by one the word which is produced by the subject and then classifies them into an appropriate process. The writer also makes the comparison between two subjects in producing the words and sees if there are some changes of the subjects in pronouncing the words during two months of observation. When all of the stages in analysis above are done, the writer then proceeds to make the conclusion. Universitas Sumatera Utara
