We report the spectra of magnetically induced electric dipole absorption inEu$_{0.75}$Y$_{0.25}$MnO$_3$ from temperature dependent far infraredspectroscopy (10-250 cm$^{-1}$). These spectra, which occur only in the $e||a$polarization, consist of two relatively narrow electromagnon features thatonset at $T_{FE}=30$ K and a broad absorption band that persists totemperatures well above $T_N=47$ K. The observed excitations account for thestep up of the static dielectric constant in the ferroelectric phase. Theelectromagnon at 80 cm$^{-1}$ is observed to be strongly coupled to the nearbylowest optical phonon which transfers more than 1/2 of its spectral weight tothe magnon. We attribute the origin of the broad background absorption to thetwo magnon emission decay process of the phonon.
