Spoken term detection (STD) provides an efficient means for content based indexing of
speech. However, achieving high detection performance, faster speed, detecting ot-of …

Systems and methods for processing a query include deter mining a plurality of sets of
match candidates for a query using a processor, each of the plurality of sets of match …

This paper considers the problem of constructing an efficient inverted index for the spoken
term detection (STD) task. More specifically, we construct a deterministic weighted finite …

Spoken content retrieval refers to directly indexing and retrieving spoken content based on
the audio rather than text descriptions. This potentially eliminates the requirement of …

Spoken content in languages of emerging importance needs to be searchable to provide
access to the underlying information. In this paper, we investigate the problem of extending …

The goal of spoken term detection (STD) technology is to allow open vocabulary search over
large collections of speech content. In this paper, we address cases where search term (s) of …

Abstract Out-of-vocabulary (OOV) words represent an important source of error in large
vocabulary continuous speech recognition (LVCSR) systems. These words cause …

The paper describes a state-of-the-art spoken term detection system in which significant
improvements are obtained by diversifying the ASR engines used for indexing and …

Automatic speech recognition is a core component of many applications, including keyword
search. In this paper we describe experiments on acoustic modeling, language modeling …
