Acceptability of temporal naturalness and temporal discrimination threshold were measured for various vowel segments in isolated words by modifying original segmental durations. A large size perceptual experiment using 1462 stimuli of 70 segments revealed that word acceptability is affected by the segment attributes and context such as vowel color, position in a word and, accent. An additional experiment showed that the above factors also affect discrimination threshold consistently.
