A study of the phonetic combination of a constrictive consonant (specifically, [f], [v], and [r]) and a vowel in French using x-ray and oscillograph technology focused on the speed and process of articulation between the consonant and the vowel. The study considered aperture size, nasality, labiality, and accent. Articulation of a total of 407 phrases or expressions covering about 570 different phonetic combinations were analyzed by means of x-ray films and oscillograms for both articulatory and acoustic evidence. They were finally submitted to auditory examination to determine how well the ear hears the phenomena recorded by the machines. A single French Canadian native speaker provided the entire linguistic corpus. The resultant analyses are reported in detail in narrative and tabular form. (MSE)
