With the development of web services, the retrieval of relevant services has become a challenge. Keyword based discovery mechanism is insufficient, due to retrieval of large amount of irrelevant information. Here we propose a semantic search engine to conquer this problem. Semantics with meaning and use of data brings information closer to human thinking and decision making. In this work, we have described voice enabled ontology based search engine for blind. Here we use conceptual based search engine. This search receives the user query through voice and converts them into text with the help of software; this text is progressed in the ontology list and produces the exact result using semantic web. The displayed text is converted into voice.
