The L2F Language Verification System for NIST LRE 2009

چکیده
This paper presents a description of the INESC-ID’s Spoken Language Systems Laboratory (LF) Language Verification system submitted to the 2009 NIST Language Recognition evaluation. The LF system is composed by the fusion of eight individual sub-systems: four phonotactic systems and four acoustic based methods. Language recognition results have been submitted for the “closed-set”, “open-set” and all the “languagepair” conditions except for the English American versus English Indian pair. The data used for training both the phonotactic and the acoustic models, the calibration and fusion development data and measurements of the processing time of the complete system during test are also described in this document.

This paper summarizes the BUT-AGNITIO system for NIST Language Recognition Evaluation 2009. The post-evaluation analysis aimed mainly at improving the quality of the data (fixing language label problems and detecting overlapping speakers in the training and development sets) and investigation of different compositions of the development set. The paper further investigates into JFA-based acousti...
متن کاملFusing language information from diverse data sources for phonotactic language recognition
The baseline approach in building phonotactic language recognition systems is to characterize each language by a single phonotactic model generated from all the available languagespecific training data. When several data sources are available for a given target language, system performance can be improved using language source-dependent phonotactic models. In this case, the common practice is t...
