Abstract: Developed tool is one of system tools for easier access to various scientific areas and real time interactive learning between
lecturer and for hearing impaired students. There is no demand for the lecturer to know Sign Language (SL). Instead, the new software
tools will perform the translation of the regular speech into SL, after
which it will be transferred to the student. On the other side, the
questions of the student (in SL) will be translated and transferred to
the lecturer in text or speech. One of those tools is presented tool. It-s
too for developing the correct Speech Visemes as a root of total communication method for hearing impared students.
Abstract: Databases have become ubiquitous. Almost all IT applications are storing into and retrieving information from databases. Retrieving information from the database requires knowledge of technical languages such as Structured Query Language (SQL). However majority of the users who interact with the databases do not have a technical background and are intimidated by the idea of using languages such as SQL. This has led to the development of a few Natural Language Database Interfaces (NLDBIs). A NLDBI allows the user to query the database in a natural language. This paper highlights on architecture of new NLDBI system, its implementation and discusses on results obtained. In most of the typical NLDBI systems the natural language statement is converted into an internal representation based on the syntactic and semantic knowledge of the natural language. This representation is then converted into queries using a representation converter. A natural language query is translated to an equivalent SQL query after processing through various stages. The work has been experimented on primitive database queries with certain constraints.
