The Cygnus region of the sky hosts different types of radio-emitting sources, such as supernova remnants, binary stellar systems, protoplanetary disk-like sources, and is also a very rich area in young stellar objects. These objects, evidences of the first stages of star formation, are classified into types according to their evolutionary stage, following their spectral index in the infrared. Using the Giant Metrewave Radio Telescope (GMRT), an area of $\sim$ $10~\text{deg}^2$ of Cygnus was surveyed in two bands. The region contais $\approx 730$ young stellar objects, mostly in the association of Cygnus OB2, of which 22 were detected in radio waves. We present preliminary results of a study of the emission detected with the GMRT at the position of these objects, especifically their radio flux density spectral index, in order to unveil physical processes acting on them.
