An intonation curve stylization was used for an acoustical analysis of English speech. For the analysis, acoustical featurevalues were extracted from 1,848 utterances produced with normal and fast speech rate by 28 (12 women and 16 men) nativespeakers of English. Men are found to speak faster than women at normal speech rate but no difference is found betweengenders at fast speech rate. Analysis of pitch point features has it that fast speech has greater Pt (pitch point movementtime), Pr (pitch point pitch range), and Pd (pitch point distance) but smaller Ps (pitch point slope) than normal speech. Menshow greater Pt, Pr, and Pd than women. Analysis of sentence level features reveals that fast speech has smaller Sr (sentencelevel pitch range), Sd (sentence duration), and Max (maximum pitch) but greater Ss (sentence slope) than normal speech. Women show greater Sr, Ss, Sp (pitch difference between the first pitch point and the last), Sd, MaxNr (normalized Max),and MinNr (normalized Min) than men. As speech rate increases, women speak with greater Ss and Sr than men.
