The Voice Česko Slovensko (Czech and Slovak for The Czech / Slovak Voice, literally The Voice of Czecho Slovakia, previously Hlas Česko Slovenska) is a reality singing competition and version of The Voice of Holland for Czech Republic and Slovakia. It is broadcast on TV Nova in Czech Republic and TV Markíza in Slovakia, both stations are owned by CME. It is derived from the original The Voice of Holland. The concept of the competition consists of searching for singer talents (from the second row and duets) over 16 years of age in public casting. The winner is later determined on the basis of a voting vote by SMS, which receives financial rewards and the ability to upload his own album.

Czechs and Slovaks in this show are communicating jointly without language change.
