Automatic phonetic segmentation
- D. Toledano, L. H. Gómez, Luis Villarrubia Grande
- Computer ScienceIEEE Trans. Speech Audio Process.
- 1 November 2003
The most frequently used approach-based on a modified Hidden Markov Model (HMM) phonetic recognizer is analyzed, and a general framework for the local refinement of boundaries is proposed, and the performance of several pattern classification approaches is compared within this framework.

It is shown how the evaluation of DNA evidence, which is based on a probabilistic similarity-typicality metric in the form of likelihood ratios (LR), can also be generalized to continuous LR estimation, thus providing a common framework for phonetic-linguistic methods and automatic systems.
Skin Detection -a Short Tutorial
Several computer vision approaches have been developed for skin detection, which typically transforms a given pixel into an appropriate color space and then uses a skin classifier to label the pixel whether it is a ski n or a non-skin pixel.
BiosecurID: a multimodal biometric database
- Julian Fierrez, Javier Galbally, Javier Garrido Salas
- Computer SciencePattern Analysis and Applications
- 25 February 2009
A new multimodal biometric database, acquired in the framework of the BiosecurID project, is presented together with the description of the acquisition setup and protocol and features such as: realistic acquisition scenario, balanced gender and population distributions, availability of information about particular demographic groups, and compatibility with other existing databases.
An end-to-end approach to language identification in short utterances using convolutional neural networks
- Alicia Lozano-Diez, Rubén Zazo-Candil, J. Gonzalez-Dominguez, D. Toledano, J. González-Rodríguez
This work has been supported by project CMC-V2: Caracterizacion, Modelado y Compensacion de Variabilidad en la Senal de Voz (TEC2012-37585-C02-01), funded by Ministerio de Economia y Competitividad,…
An analysis of the influence of deep neural network (DNN) topology in bottleneck feature based language recognition
- Alicia Lozano-Diez, Ruben Zazo, D. Toledano, J. González-Rodríguez
- Computer SciencePloS one
- 10 August 2017
Analysis of language recognition results with different topologies for the DNN used to extract the bottleneck features, comparing them and against a reference system based on a more classical cepstral representation of the input signal with a total variability model to obtain useful knowledge about how the Dnn configuration influences bottleneck feature-based language recognition systems performance.
Synthetic Fingerprint Generation
Assessment of Severe Apnoea through Voice Analysis, Automatic Speech, and Speaker Recognition Techniques
- Rubén Fernández Pozo, José Luis Blanco Murillo, L. A. H. Gómez, E. Gonzalo, J. A. Ramírez, D. Toledano
- MedicineEURASIP J. Adv. Signal Process.
An acoustic search for distinctive apnoea voice characteristics is described and an 81% correct classification rate is achieved, which is very promising and underpins the interest in this line of inquiry.
Automatic alternative transcription generation and vocabulary selection for flexible word recognizers

- 21 April 1997
This work proposes the use of the new transcription confusability measure in two different word error rate (WER) reduction procedures for FVRs: an automatic vocabulary selection procedure suitable for those applications where the set of vocabulary words is not totally defined by the application, and an automatic procedure for generation of alternative transcriptions.
