  We present the VST Optical Imaging of the CDFS and ES1 Fields (VOICE) Survey,
a VST INAF Guaranteed Time program designed to provide optical coverage of two
4 deg$^2$ cosmic windows in the Southern hemisphere. VOICE provides the first,
multi-band deep optical imaging of these sky regions, thus complementing and
enhancing the rich legacy of longer-wavelength surveys with VISTA, Spitzer,
Herschel and ATCA available in these areas and paving the way for upcoming
observations with facilities such as the LSST, MeerKAT and the SKA. VOICE
exploits VST's OmegaCAM optical imaging capabilities and completes the
reduction of WFI data available within the ES1 fields as part of the
ESO-Spitzer Imaging Extragalactic Survey (ESIS) program providing $ugri$ and
$uBVR$ coverage of 4 and 4 deg$^2$ areas within the CDFS and ES1 field
respectively. We present the survey's science rationale and observing strategy,
the data reduction and multi-wavelength data fusion pipeline. Survey data
products and their future updates will be released at
http://www.mattiavaccari.net/voice/ and on CDS/VizieR.
