Male and female Castillian-Spanish (es_ES) voices «PAL» and «SFL» for Festival.

This is a diphone-based male Spanish voice for the Festival speech synthesis
system. These original audio files were recorded by a professional voice talent
in a recording studio.

This voice was developed by the Consejeria de Innovacion, Ciencia y Empresa of
the Junta de Andalucia on a project awarded to MP Sistemas in collaboration with
Intelligent Dialogue Systems (INDISYS).

The primary objective was to integrate a higher-quality diphone-based Spanish
voice in Guadalinex v4.0, an Ubuntu-based Linux distribution promoted by the
Government of Andalusia (Spain). See http://www.guadalinex.org for more
