ALBAYZIN 2014 – AUDIO SEGMENTATION EVALUATION

The Albayzin 2014 Audio Segmentation Evaluation organized by Vivolab research group (http://www.vivolab.es/) from the University of Zaragoza will be conducted as part of Iberspeech 2014  ( "VIII Jornadas en Tecnología del Habla"and IV Iberian SLTech Workshop)  (http://iberspeech2014.ulpgc.es/) organized by the University of Las Palmas de Gran Canaria and supported by the Spanish Thematic Network on Speech Technology (RTTH) and the ISCA Special Interest Group on Iberian Languages (SIG-IL) that will take part in Las Palmas de Gran Canaria (Spain),  19-21 November 2014.

This evaluation consists of segmenting and labeling broadcast audio documents to indicate which segments contain speech, music and/or noise. Unlike previous editions, this evaluation aims at providing an experimental framework for segmentation systems across different databases that can be merged or even overlapped increasing the difficulty from last editions. Therefore, the main goal is to test the robustness of the participating systems against different acoustic contexts.


Data

The database for this evaluation is a combination and fusion of several databases:
The Catalan broadcast news database from the 3/24 TV channel proposed for the 2010 Albayzin Audio Segmentation Evaluation, the Aragon Radio database from the Corporacion Aragonesa de Radio y Television (CARTV) which was used for the 2012 Albayzin Audio Segmentation Evaluation, and sounds extracted from different sources (Freesound.org, HuCorpus from Ohio State University, ...). This sounds will be merged with segments from the 3/24 TV and Aragon Radio databases. All the data will be supplied in PCM format, mono, little endian 16 bit resolution, and 16 kHz sampling frequency.


Metrics

As in the NIST RT Diarization evaluations, to measure the performance of the proposed systems, the segmentation error score (SER) will be computed as the fraction of class time that is not correctly attributed to that specific class (speech, noise or music). This score will be computed over the entire file to be processed; including regions where more than one class is present (overlap regions). This score will be the ratio of the overall segmentation error time to the sum of the durations of the segments that are assigned to each class in the file.
