"Se Me Va la Voz" (English: Losing My Voice)[1] is a Spanish language song by Mexican singer Alejandro Fernández released as the lead single from his seventh studio album, Dos Mundos: Evolucion.

It is a continuation of "Estuve", where the story of a love triangle emphasizes the concept of karma, where each action has a reaction, its own effect equal or worse in magnitude, and this video entails the consequences of the betrayal.

The videos had the participation of the Puerto Rican actor Luis Roberto Guzmán and Mexican actress Aislinn Derbez, who gives life to Alejandro's woman according to the script.

The first day was filmed in a Hacienda located 30 minutes from Guadalajara, hidden between nature and panoramic views to the ‘barranca of Hentitan’, birthplace of Don Vicente Fernández, Alejandro's father.

Over a period of two days of filming more than 100 extras participated all natives of Guadalajara and the collaboration of 30 elements of security including, an ambulance, a crane, and several patrol cars.
