Kepler satellite has been producing several hundredths of light curves of Solar like stars since the late summer of 2009. The only way to process all the data in a reasonable time is to develop a semi automatic method, which includes the use of Bayesian priors. We investigate different methods to fit a huge amount of stellar oscillations spectra, in order to extract their mode parameters (frequency, width, height). In particular, we analyze the delicate approach to take into account the mixed modes, for which the absence of regular spacing between the mode overtones generates difficulty to identify them.
