A method and a system for searching voice data at high speed with document extension are provided to search voice data at a high speed by indexing a voice document with a phoneme n-gram, which binds n continuous phonemes obtained from a phoneme recognizer, and remarkably reducing a calculation quantity with an efficient document extension technique. A voice recognizer(30) receives voice document data and a query receiver(40) receives a user query. A main system(10) is connected to the voice recognizer and the query receiver, and includes a voice recognition engine(11) converting the voice data or the user query into a phoneme n-gram, and an information search engine(12) searching/sorting the voice document corresponding to the user query. A voice document database(20) is connected to the main system, and stores the voice document data, and the phoneme n-gram corresponding to the voice document data and converted by the voice recognition engine. An output part(50) outputs a result searched and sorted by the information search engine. The query receiver and the output part are connected with the main system through the Internet.
