The characteristics of steady state fricative production, and those of the phone preceding and following the fricative, were investigated. Aerodynamic and electroglotographic (EGG) recordings of four normal adult speakers (two females and two males), producing a speech corpus of 9 isolated words with the European Portuguese (EP) voiced fricatives /v, z, Z/ in initial, medial and final word position, and the same 9 words embedded in 42 different real EP carrier sentences, were analysed. Multimodal data allowed the characterisation of fricatives in terms of their voicing mechanisms, based on the amplitude of oral flow, F1 excitation and fundamental frequency (F0).
