The conversation between the two girls is balanced and with little lexical and acoustic dysfluency and with only some syntactic dysfluency being noted, insofar as to retracing, repetition, and meaningless syllables. The number of words is bit more balanced but Kaho is roughly a 100 hundred shy of Toko’s number of words at 365. While there are longer and more informative utterances, many of them are somewhat comprehensible due to the fragmentation and level of grammatical accuracy. However, both girls share enough background about Kitakyushu and Fukuoka that an animated and successful conversation was possible, despite the dysfluency.
This discussion between Yuki and Hikaru reflects a high speaking rate, with a low percentage of silence (5.6%) and little lexical and syntactic analysis, though there is a high level of repetition with Yuki. Mean length runs are rather short, 6.2 and 7.7. and the number of words is about low (281) to average (369). The conversation is spirited and the men are engaged. I would recommend that both men take more time to explain and to provide more background when telling a story or explaining a preference.
This discussion between Yuri and Megumi shows a higher level of speaking rate for Yuri, 104.6, and a lower one for Megumi. There is a low rate of silence of 5.7% The girls are are very animated, Mean length runs are 7.6 for Yuri’s and 6.5 for Megumi. And there is low acoustic dysfluency 5.0%, as well as a low lexical and syntactic dysfluency, though the levels of repetition could be lower. The interaction is balanced, with 254 words for Yuri and 248 for Megumi. In short, this is a good example of fluency in same-sex interactions, though minimal responses are bit too frequent.
This discussion is notable insofar that there is an extremely high level of silence, particularly with cross-talk pausing, 125.3 seconds, and overall there was a 184.6 seconds or 29.9%. This reflects that the two women were somewhat ill-at-ease in finding common ground, though, again, this may not be apparent from just watching the video. Minimal responses are extremely common throughout this discussion, and MLRs are very short as well, 5.7 for Nanami and 5.6 for Nozomi. The number of words is on the low-side, around 253 and 223.
This second same-sex discussion was interesting as both males had high speaking rates 116.2 and 116.7, with no cross-talk pausing. Dysfluency is limited though Kohei had a high level of repetition (38 occurrences) as well as a high level of meaningless syllables 96. There is some unbalance to the discussion with Shohei talking more than twice as long as Kohei, so my recommendations would be that Kohei provide more descriptive responses and stories.
Both males have a high speaking rate, 106.5 for Sho, and 112.6 for Naoyuki. Cross-talk pausing is not very high, 19.0 seconds, as well as the percentage of silence, 9.9% though this is 74.8 seconds. Mean length runs are fairly normal 12.6/9.0, and both participants are productive, with Naoyuki having 640 words and Sho having 441 words. Both males have few minimal responses
