The data in this article present position-dependent variation of focus prosody within phone number strings in Tokyo Japanese. Four acoustic parameters (duration, mean intensity, maximum pitch, and time-normalized pitch contours) are reported to illustrate focus prosody of Japanese phone numbers, separately for broad focus and corrective focus. The data also include four attached files: 1) time-normalized pitch contours for all speakers (Appendix A), 2) aggregated data of duration, mean intensity, and maximum pitch for on-focus effects (Appendix B), 3) a Python script automatically generating target stimuli (Appendix C), and 4) target stimuli used for each focus type (Appendix D). The data set can be used for several research projects including speech recognition, focus study, speaker variation in marking prosodic focus, and prosody modeling in Tokyo Japanese. Detailed discussion of data interpretation can be found in the article entitled “Prosodic focus of telephone numbers in Tokyo Japanese” (Lee et al.).
