Declarative and Interrogative Speech Contrast in Toba Batak Language: Acoustic Phonetic Studies

Introduction

Language is a vital tool for human communication, serving as a symbol of sounds produced through words. As one of the social and natural phenomena, language requires examination and understanding. The main purpose of linguistics is to explain and explain various symptoms that occur in nature and society. This study aims to provide new knowledge about language, focusing on the acoustic characteristics of declarative and interrogative speech in the Toba Batak language.

The Importance of Language Study

Language is a complex and multifaceted phenomenon that plays a crucial role in human communication. It is a vital aspect of culture, identity, and social interaction. The study of language is essential in understanding the complexities of human communication, as well as the cultural and social contexts in which language is used. This study aims to contribute to the existing body of knowledge on language, specifically focusing on the acoustic characteristics of declarative and interrogative speech in the Toba Batak language.

Background of the Study

The Toba Batak language is a member of the Austronesian language family, spoken by the Toba Batak people in North Sumatra, Indonesia. The language has a rich cultural and historical significance, with a unique grammatical and phonological structure. Despite its importance, the Toba Batak language is considered an endangered language, with a decreasing number of native speakers. This study aims to contribute to the preservation and documentation of the Toba Batak language, specifically focusing on the acoustic characteristics of declarative and interrogative speech.

Research Methodology

This study employed a mixed-methods approach, combining both qualitative and quantitative data collection and analysis methods. The sample consisted of 20 participants from the Toba Batak community in Medan, Indonesia. The data was collected through a series of acoustic phonetic experiments, using a digital audio recorder and software for data analysis. The data was then analyzed using acoustic phonetic theory, specifically focusing on the melodic structure and temporal characteristics of declarative and interrogative speech.

Acoustic Phonetic Theory

Acoustic phonetic theory is a branch of linguistics that focuses on the physical properties of speech sounds. It provides a framework for understanding the acoustic characteristics of speech, including the melodic structure and temporal characteristics. This study employed the acoustic phonetic theory developed by Van Heuven and Sugiyono, which provides a strong theoretical foundation for understanding the phenomenon under study.

Research Results

The results of this study indicate that there is a significant melodic structure in distinguishing declarative speech from interrogative speech. Some of the factors found are:

Tiecular tone: the tone of the tone used can distinguish declarative speech from causal interrogative and time interrogative.
Basic tone and final tone: Both cannot be used as a distinguishing factor between declarative and interrogative speech.
Highest tone: found as a differentiator between declarative and interrogative speech, although it is not effective in distinguishing interrogative and interrogative speech confirmatory.
The lowest tone: functions as a differentiator between declarative and interrogative speech, except in causal and interrogative interrogative cases.

Tempo Significance

The most significant aspect in this study is the temporal characteristic of speech, which allows clear distinguishing between these two types of speech. Tempo in declarative speech has a different pattern compared to interrogative, so that it can be a reliable indicator in acoustic phonetic analysis.

Conclusion

This study plays an important role in understanding the acoustic characteristics of the Toba Batak language, especially in the context of declarative and interrogative speech. With the results obtained, it is expected that there will be further developments in phonetic and acoustic studies, as well as the restoration of identity and protection of regional languages that are rich in cultural values. Understanding the differences and uniqueness of language is an important step in preserving the culture and heritage of the nation.

Recommendations

Based on the findings of this study, the following recommendations are made:

Further research is needed to explore the acoustic characteristics of other languages, specifically focusing on the melodic structure and temporal characteristics of declarative and interrogative speech.
The results of this study can be used as a reference for language teaching and learning, specifically focusing on the acoustic characteristics of declarative and interrogative speech in the Toba Batak language.
The preservation and documentation of the Toba Batak language is essential, and this study contributes to the existing body of knowledge on the language.

Limitations

This study has several limitations, including:

The sample size was limited to 20 participants, which may not be representative of the entire Toba Batak community.
The study focused on the acoustic characteristics of declarative and interrogative speech, and did not explore other aspects of the language.
The study was conducted in a laboratory setting, which may not reflect the natural speech environment.

Future Directions

This study provides a foundation for further research on the acoustic characteristics of language, specifically focusing on the melodic structure and temporal characteristics of declarative and interrogative speech. Future studies can explore the following directions:

Investigating the acoustic characteristics of other languages, specifically focusing on the melodic structure and temporal characteristics of declarative and interrogative speech.
Exploring the relationship between acoustic characteristics and language teaching and learning.
Documenting and preserving regional languages that are rich in cultural values.
