A Bayesian inference model for speech localization (L)

Escolano Carrasco, José; Pérez Lorenzo, José Manuel; Xiang, Ning; Cobos Serrano, Máximo; López Monfort, José Javier (Acoustical Society of America, 2012-09)

The localization of active speakers with microphone arrays is an active research line with a considerable interest in many acoustic areas. Many algorithms for source localization are based on the computation of the Generalized ...
A comparison of different techniques for simulating and measuring acoustic parameters in a place of worship: Sant Jaume Basilica in Valencia, Spain

Segura Garcia, Jaume; Giménez Pérez, Alicia; Romero Faus, José; Cerdá Jordá, Salvador (Hirzel Verlag (S. Hirzel Verlag), 2011-01)

The study of rooms devoted to sound transmission has become a discipline in which all the fundamentals areas of current scientific research in acoustics converge. To demonstrate how this convergence arises in this work, ...
A prosody-based vector-space model of dialog activity for information retrieval

Ward,Nigel G.; Werner, Steven D.; García-Granada, Fernando; Sanchís Arnal, Emilio (Elsevier, 2015-04)

Search in audio archives is a challenging problem. Using prosodic information to help find relevant content has been proposed as a complement to word-based retrieval, but its utility has been an open question. We propose ...
Automatic speech recognition in cocktail-party situations : a specific training for separated speech

Martí Guerola, Amparo; Cobos Serrano, Máximo; López Monfort, José Javier (Acoustical Society of America, 2012-02)

Automatic speech recognition (ASR) refers to the task of extracting a transcription of the linguistic content of an acoustical speech signal automatically. Despite several decades of research in this important area of ...
Estudio de modelos predictivos del tiempo de reverberación y parámetros de calidad.

Pérez Maciá, José Joaquín (Universitat Politècnica de València, 2021-01-12)

[ES] El presente trabajo trata sobre el estudio de modelos predictivos del tiempo de reverberación y otros parámetros acústicos de calidad en recintos considerados acústicamente especiales. El parámetro principal del trabajo ...
Maximum a Posteriori Binary Mask Estimation for Underdetermined Source Separation Using Smoothed Posteriors

Cobos Serrano, Máximo; López Monfort, José Javier (Institute of Electrical and Electronics Engineers (IEEE), 2012-09)

Sound source separation has become a topic of intensive research in the last years. The research effort has been specially relevant for the underdetermined case, where a considerable number of sparse methods working in the ...
Metodología para la mejora acústica de recintos de culto. Aplicación en la Catedral de Valencia

Díaz-Rubio, Elena; Montell Serrano, Radha Empar; Cerdá Jordá, Salvador; Segura Garcia, Jaume; Cibrián Ortíz de Anda, Rosa; Barba Sevillano, Arturo; Lacatis, Radu George; Planells Pérez, Ana; FAYOS JORDAN, RAFAEL; NAVASQUILLO HERVÁS, JOAQUÍN; Giménez Pérez, Alicia (SOCIEDAD ESPAÑOLA DE ACUSTICA, 2021)

[ES] Los recintos de culto son espacios patrimoniales de gran valor cultural, artístico y arquitectónico. Asimismo, en ellos tienen lugar eventos, integrantes de su patrimonio cultural inmaterial, donde la transmisión del ...
Robust acoustic source localization based on modal beamforming and time-frequency processing using circular microphone arrays

Torres Aranda, Ana María; Cobos Serrano, Máximo; Pueo Ortega, Basilio; López Monfort, José Javier (Acoustical Society of America, 2012-09)

Uniform circular array processing has been shown to be a very useful tool for broadband acoustic source localization over 360 degrees. Specifically, beamforming methods based on circular harmonics have attracted a lot of ...
Speaker-Adapted Confidence Measures for ASR using Deep Bidirectional Recurrent Neural Networks

Del Agua Teba, Miguel Angel; Giménez Pastor, Adrián; Sanchis Navarro, José Alberto; Civera Saiz, Jorge; Juan, Alfons (Institute of Electrical and Electronics Engineers, 2018)

[EN] In the last years, Deep Bidirectional Recurrent Neural Networks (DBRNN) and DBRNN with Long Short-Term Memory cells (DBLSTM) have outperformed the most accurate classifiers for confidence estimation in automatic speech ...
Speech and singing voice classifier based on musical note classification and fundamental frequency estimation.

Diana Sánchez, Santiago (Universitat Politècnica de València, 2022-10-14)

[ES] El procesamiento del habla es el estudio de las señales del habla y de los métodos de procesamiento de señal aplicados al análisis y el tratamiento de las mismas. Este tratamiento es actualmente realizado en el dominio ...
Speech recognition with the Zowi robot

Tecles del Romero, Carlos (Universitat Politècnica de València, 2019-01-10)
