English Speech Production of Native Sinhala Speakers with Special Reference to Interlanguage Analysis
(Faculty of Humanities and Sciences, SLIIT, 2022-09-15) Wijayabandara, H.M.T
Native Sinhala speakers attempt to speak in English even prior to formal education regardless of the errors they make in speech production. This study is focused on interlanguage, the linguistic system behind the learner language of these native speakers, influenced by the first language and the target language. This research was conducted to analyze the impact of the Sinhala language on the English speech production of native speakers. A qualitative research approach was taken to initiate this research with 30 native Sinhala speakers, who informally learnt to speak English. They were asked to interpret a few simple English sentences to Sinhala. Each translated utterance was simultaneously recorded and analyzed to observe the produced patterns of the inter-language. Results indicate that the inter-language production of the speakers was visible in the structure of language and specific grammar rules about spoken English. Syntactic pattern, word order, misidentifying nouns and adjectives, omission of the ‘be verbs’, the misconception of verb tenses, and chaotic pronoun placement are included in the native language influence. The findings of this inter-language analysis concluded that the native language is a dominant factor in second language speech production. Competence in the first language is the main reason for this dominance since the speaker tries to perceive a second language most comfortably. Further, the importance of introducing Psycholinguistics in Sri Lanka is emphasized.

Universal Sinhala Library: Language Specific Encryption Platform for Sinhala Language
(researchgate.net, 2022-02) Thelijjagoda, S; Webadu Wedanage, D, K, H
Security has become a significant challenge in the modern world. Number science and mathematics opened up a vast path to work with programming models to create innovative mechanisms which improve text encryption. Universal Sinhala Library is a Sinhala language-specific text encryption platform. Platform architecture has been designed to demonstrate every possible combination of the Sinhala alphabet, including comma, space and period. The hypothetical architecture includes every book that ever has been written in Sinhala, and every book that ever could be, including every poem, every scientific paper and every piece of document in Sinhala. The main goal of the research is to create an encryption mechanism for the Sinhala language. Linear congruential generator and extended euclidean algorithm have been used along with the Hull–Dobell Theorem to outline the backbone of the encryption platform. At present, it contains all possible combinations of Sinhala characters virtually. Sinhala text to be encrypted should be searched in the platform, and it will return the location of that particular text in the virtual library architecture, which is the encrypted text string for the searched Sinhala text. It is helpful to the people who are using or working with the Sinhala language, moreover for sharing and transferring Sinhala context securely.

Optical character recognition for Sinhala language
(IEEE, 2013-08-23) Rimas, M; Thilakumara, R. P; Koswatta, P
A rotationally invariant optical character recognition system for Sinhala language is developed using Two Dimensional Fourier Transform and Artificial Neural Networks. Sinhala characters of different fonts and font sizes are recognized with over 85% recognition accuracy. Segmentation method based on histogram used in this system gives segmentation accuracy over 70% for complex Sinhala characters.

Intelligent mobile assistant for hearing impairers to interact with the society in Sinhala language
(IEEE, 2017-12-06) Perera, Y; Jayalath, N; Tissera, S; Bandara, o; Thelijjagoda, S
A language is a way of words or signs that people use to share feelings and ideas with each other. In view of the society there is an issue in communication among hearing impaired people and hearing people. Most of the hearing people have no idea about the sign languages and they are not having any desire to learn sign language. Thus, typically hearing impairers are used to be isolated. When considering about all the solutions there is an absence of a Sinhala application with Sinhala sign language. Sinhala is the native language of the Sinhalese people. Sinhala is one of the official and national languages of Sri Lanka, who make up the largest ethnic group in Sri Lanka, numbering about 20 million. Sinhalese is also spoken as a second language by other ethnic groups in Sri Lanka, totaling about four million. Since most of the solutions are desktop applications, hearing impairers feel so uncomfortable. In the modern era where mobile technology plays a superior role in day to day life, Project “Sanwadha” is an intelligent assistant for the hearing-impaired people for communication. The proposed application is under cross platform mobile development where users can reach the solution widely. The core of the Project “Sanwadha” is Instant Messaging (IM) chat. Here the application will get the text from the ordinary person in Sinhala language and it converts to Sinhala sign language. The message will be directing to hearing impaired person in a format of GIF. 2D model can be used by the User (Hearing impaired) to grasp the idea by creating the sign as they wish. That sign would be altering in to either Text or Voice to interact with the society. Hearing people also can cooperate with the hearing impairers with the voice recognition mechanism. This solution would come up with an intelligent application where hearing impairers makes empower in the society through communication. Reaching Sri Lankan deaf community is another foremost objective of this project. This hopes to narrow digital divide that between enabled and hearing- impaired users. The significance of this proposed application is that it allows hearing-impaired individuals to communicate when they are long distance apart. This application would bridge the gap between hearing impairers with the society.
