We aim to determine the fundamental parameters of a sample of B stars withapparent visual magnitudes below 8 in the field-of-view of the CoRoT spacemission, from high-resolution spectroscopy. We developed an automatic procedurefor the spectroscopic analysis of B-type stars with winds, based on anextensive grid of FASTWIND model atmospheres. We use the equivalent widthsand/or the line profile shapes of continuum normalized hydrogen, helium andsilicon line profiles to determine the fundamental properties of these stars inan automated way. After thorough tests, both on synthetic datasets and on veryhigh-quality, high-resolution spectra of B stars for which we already hadaccurate values of their physical properties from alternative analyses, weapplied our method to 66 B-type stars contained in the ground-based archive ofthe CoRoT space mission. We discuss the statistical properties of the sampleand compare them with those predicted by evolutionary models of B stars. Ourspectroscopic results provide a valuable starting point for any future seismicmodelling of the stars, should they be observed by CoRoT.
