摘要
In a method for evaluating the voice onset of a speaker, especially suited for treatment of a stuttering disorder, the analysis includes: a. determine a time of voice onset of the speaker; b. obtain a fundamental frequency at the time of voice onset; c. in a predetermined time interval, obtain the curve with respect to time of energy at the fundamental frequency; d. obtain the curve with respect to time of energy at at least one harmonic multiple of the fundamental frequency; and e. determine the temporal progression of the ratio of the energies obtained in steps c and d. A gentle voice onset is presumed if the energy ratio is initially dominated by the energy of the fundamental frequency, and only in the further course of the predetermined time interval in a time span of Δt the energy ratio shifts in favor of the energy/energies of the harmonic multiple(a) of the fundamental frequency.
