“…Thus, the transitions of F1 and F2 were fixed throughout the continuum. The F3 transition was decided using the data provided by MacKain et al [5] (see also [9,10]). The starting frequency of F3 varied from 1,609 Hz (/ra/ configuration) to 2,827 Hz (/la/ configuration) in ten nearly equal steps (Step 1 through Step 10).…”

“…1) were also varied in ten steps from 1,717 Hz to 2,827 Hz. These values were again based on the data from MacKain et al [5] (see also [9,10]). During the transition period, F3 of each step at 0 ms rose linearly to the value of the corresponding step at the inflection; then, the value at the inflection increased or decreased linearly to the steady state.…”

“…The transitions of F1 and F2 were fixed referring to a preliminary experiment [9,10] (see Appendix). Because characteristic changes in F1 and F2 also contribute to the perception of the /r/-/l/ contrast to some extent [4], fixed transitions were set to be as ''neutral'' as possible.…”

The discrimination of an /r/-/l/ speech continuum presented in an isolated monosyllabic context has been studied by a number of researchers. However, when one considers normal listening environments, it is unusual for people to hear syllables in isolation. In the present research, we investigated whether the characteristics of the discrimination performance for a /ra/-/la/ continuum presented under the isolated condition are also observed when the continuum is presented under nonisolated conditions, or more ordinary listening conditions. Two nonisolated conditions were employed: 1) the continuum was presented within a sentence, and 2) the continuum was preceded and followed by pure tones. Experiments revealed that the discrimination performance under condition 2) was similar to that under the isolated condition; however, the performance under condition 1) was different from those under the other conditions. The research suggests that the characteristics of the discrimination performance under nonisolated conditions are not necessarily identical to those under the isolated condition.
