This study investigated longitudinally early vocalization and phonological developments of typically developing children. Ten typically developing children participated in the study from 9 months to 18 months of age. Spontaneous utterance samples were collected at 9, 12, 15, 18 months of age and phonetically transcribed and analyzed. Utterance samples were classified into 5 levels using Stark Assessment of Early Vocal Development-Revised(SAEVD-R). The data analysis focused on 4 and 5 levels of vocalizations classified by SAEVD-R and word productions. The percentage of each vocalization level, vocalization length, syllable structures, and consonant inventory were obtained. The results showed that the percentages of level 4 and 5 vocalizations and word significantly increased with age and the production of syllable structures containing consonants significantly increased around 12 and 15 months of age. On average, the children produced 4 types of syllable structure and 5.4 consonants at 9 months and they produced 5 types of syllable structure and 9.8 consonants at 18 months. The phonological development patterns in this study were consistent with those analyzed from children's meaningful utterances in previous studies. The results support the perspective on the continuity between babbling and early speech. This study has clinical implications in early identification and speech-language intervention for young children with speech delays or at risk.

This study deals with a general review of $Gar\acute{i}funa$ and Patois, creole languages which developed out of the sociohistorical situation of the last centuries and are mainly spoken in the West Indies and Carribean Coasts. In this paper, I present some notes and ideas on the linguistic developments and features of these languages. Especially I describe their function connected with a variety of social circumstances and their phonetical/phonological changes from the base languages. This is a result of fieldwork conducted in Honduras, Belize, Cuba and Mexico, from January 1996 to February 1998, using some surveys and collecting words from different materials and texts. And I hope this paper will contribute to research in 'mixed' languages as well as to historical linguists. I am very grateful to Mr. Mauricio $Tom\acute{a}s$, the only uriversity student in $Traves\acute{i}a$, a small town in nothern Honduras and to Mr. Carlos Marcos, a medical student who is from a Haitian family in Santiago de Cuba. Without their cooperation, I couldn't have conducted this research.
