A comparison of query-by-example methods for spoken term detection

open access: closedInterspeech 2009, 2009
Abstract : In this paper we examine an alternative interface for phonetic search, namely query-by-example, that avoids OOV issues associated with both standard word-based and phonetic search methods. We develop three methods that compare query lattices derived from example audio against a standard ngrambased phonetic index and we analyze factors ...

Query-by-Example Spoken Term Detection System Based on Phoneme Posterior Features

open access: closed2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC), 2017
Spoken term detection (STD) provides an efficient means for keyword indexing of speech. However, achieving high detection performance, fast speed, detecting out-of-vocabulary (OOV) words and performing STD on low resource languages are some of the major research challenges.

Multilingual query by example spoken term detection for under-resourced languages

open access: closed2013 7th Conference on Speech Technology and Human - Computer Dialogue (SpeD), 2013
We propose a query-by-example approach to multilingual Spoken Term Detection for under-resourced languages based on Automatic Speech Recognition. The approach overcomes the main difficulties met under these conditions, i.e., providing a new method for building multilingual acoustic models with few annotated data and searching in approximate Automatic ...

Unsupervised query by example spoken term detection using features concatenated with Self-Organizing Map distances

open access: closed2013 IEEE International Conference on Multimedia and Expo (ICME), 2018
In this paper we propose a fast and memory efficient Dynamic Time Warping (MES-DTW) algorithm for the task of Query-by-Example Spoken Term Detection (QbE-STD). The proposed algorithm is based on the subsequence-DTW (S-DTW) algorithm, which allows the search for small spoken queries within a much bigger search collection of spoken documents by ...

Phonetic unit selection for cross-lingual query-by-example spoken term detection

2015 IEEE Workshop on Automatic Speech Recognition and Understanding (ASRU), 2015
Cross-lingual query-by-example spoken term detection (QbE STD) has caught the attention of speech researchers, as it makes it possible to develop systems for low-resource languages, in which the available amount of labelled data makes the training of automatic speech recognition approaches prohibitive.

CNN-based bottleneck feature for noise robust query-by-example spoken term detection

2017 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2017
This paper addresses the problem of query-by-example spoken term detection (QbE-STD) in the presence of background noises that are inevitable in real applications. To deal with this, we propose a convolutional neural network (CNN) based bottleneck feature representation for a keyword.

A fast query-by-example spoken term detection for zero resource languages

2016 International Conference on Signal Processing and Communications (SPCOM), 2016
This paper presents a novel two-pass dynamic time warping (DTW) approach to build Query-by-Example Spoken Term Detection (QbE-STD) system for Zero Resource Languages. An unconstrained-endpoint dynamic time warping (UE-DTW) algorithm is used to locate the query term occurrences in a long conversational audio.

A Stage Match for Query-by-Example Spoken Term Detection Based On Structure Information of Query

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2021
The state-of-the-art of query-by-example spoken term detection (QbE-STD) strategies are usually based on segmental dynamic time warping (S-DTW). However, the sliding window in S-DTW may separate signal of a word into different segments and produce many ...

An efficient TF-IDF based Query by Example Spoken Term Detection

2024 IEEE Conference on Artificial Intelligence (CAI)
In the present research, we tackle the problem of query by example spoken term detection (QbE-STD) in the zero-resource scenario. State-of-the-art methods typically use dynamic temporal warping (DTW) to match templates.
