In forensic speaker comparison, f0 is one among other parameters examined. However, the f0 data must be validated carefully, as it changes as a function of vocal efforts. This paper present the results of an experiment where six male and six female subjects uttered the same sentence in five speak modes: whisper, casual, normal, loud, and shout. Only voiced speech was subsequently analyzed. As a result, the fb and f0 mean as a function of vocal effort is determined. With reference to subjects’ “normal” speech level, the baseline f0 (fb) was estimated from corresponding data obtained by casual voice, loud voice, and shout.
