Recent developments in spoken term detection: a survey

Anupam Mandal, K. R. Prasanna Kumar, Pabitra Mitra
2013 International Journal of Speech Technology  
Spoken term detection (STD) provides an efficient means for content based indexing of speech.  ...  It also performs an analysis of the various approaches in terms of detection accuracy, storage requirements and execution time.  ...  In Ng and Zue (2000) , phonetic transcripts of a spoken document are obtained using a phone recognizer.  ...

Speech Retrieval [chapter]

Ciprian Chelba, Timothy J. Hazen, Bhuvana Ramabhadran, Murat Saraçlar
2011 Spoken Language Understanding  
In this chapter we discuss the retrieval and browsing of spoken audio documents.  ...  We focus primarily on the application of document search where a user provides a query and the system returns a set of audio documents that best match the query.  ...  At retrieval time, when an OOV query is encountered, the query is converted into a phone sequence and the phone index is used for retrieval.  ...

Language independent search in MediaEval's Spoken Web Search task

Florian Metze, Xavier Anguera, Etienne Barnard, Marelie Davel, Guillaume Gravier
2014 Computer Speech and Language  
The data was taken from "spoken web" material collected over mobile phone connections by IBM India as well as from the LWAZI corpus of African languages.  ...  As part of the 2011 and 2012 MediaEval benchmark campaigns, a number of diverse systems were implemented by independent teams, and submitted to the "Spoken Web Search" task.  ...  The "Spoken Web Search" task was originally proposed by researchers from IBM India .  ...

Automatic Summarization

Martha Larson
2012 Foundations and Trends in Information Retrieval  
Spoken content retrieval (SCR) requires the combination of audio and speech processing technologies with methods from information retrieval (IR).  ...  SCR research initially investigated planned speech structured in document-like units, but has subsequently shifted focus to more informal spoken content produced spontaneously, outside of the studio and  ...  . • Efficient. The representation should require a reasonable amount of computation at ASR-time and be very fast at search time.  ...

Nonparametric Bayesian Approaches for Acoustic Modeling [article]

(:Unkn) Unknown, University, My, Joseph Picone
The goal of Bayesian analysis is to reduce the uncertainty about unobserved variables by combining prior knowledge with observations.  ...  In addition to sharing data, the proposed model can learn non-ergodic structures and non-emitting states, something that HDPHMM does not support.  ...  This process is reminiscent of dynamic time warping (Furui, 1986) and is an integral part of any speech recognition training process.  ...
