This paper presents a design method for an idealized system to be applied for the study of the speech-quality dimension "directness/frequency content". Using this idealized system, we can generate degraded speech samples processed by systems with defined values of the parameters describing the above dimension. These parameters are the equivalent rectangular bandwidth ERB, the center frequency ΘG (center of gravity of the frequency content), the slope β, the ripple depth γD, and the ripple rate γR. The performance of this idealized system is evaluated by both an objective measure and a listening-only test.
