WebFormant bandwidth estimation is generally considered to be challenging due to several factors related to speech production and voice production characteristics. For exam-ple, formant bandwidth estimation has been reported to be particularly sensitive to multiple pulses within one glottal cycle and short closed-phase durations of sustained vowels Web4-fold change in bandwidth has an effect similar (in general slightly smaller) to that of a 10 dB change in ratio. Referring back to Fig. 1, a 4-fold reduction of bandwidth increases the formant peak amplitude by about 6 dB. One could thus explain target bandwidth effects by assuming (a) that narrowing a formant at constant RMS boosts its peak
