A one-way independent ANOVA with 4 factors was performed for Breakdown fluency on a total of 182 participants. This gave an F statistic of F(3,178)=43.02, p<.000, with an overall effect size Cohen D = 0.87 which is considered large. Simple contrasts with a Bonferroni correction showed that the reduction in breakdown fluency for the 20 hour treatment group, T20 (M=-0.159) was significantly better than the control group of the same time, C20 (M=-0.108, t(94)=5.45, p=.001, r=0.480). Similarly, the contrast was calculated for the control group at 5 hours, C5 (M=-0.050) and the treatment group at the same time, T5 (M=-0.118, t(84)=1.661, p=.001, r=0.726).Low and intermediate level (CEFR A2-B1) Japanese EFL learners have high breakdown fluency and low to medium speed fluency. The longest treatment group of 20 hours showed the most reduction in breakdown fluency compared to the control group of the same time. All groups improved their performance over time, i.e. demonstrated a reduction in breakdown fluency and an improvement in speed fluency compared as the length of time increased. This was true with the control groups as well from C5 to C20. Most notable is that T5 group showed a statistically equivalent amount of improvement as the C20 group. This is the strongest indication that immediate feedback, a high degree of interactivity, progress tracking and overall gamification of the digital treatment can be a more effective way of improving speaking fluency in low to intermediate learners.

进行了4个具有4个因子的独立ANOVA，以实现总共182名参与者的分解流畅性。这给出了F（3,178）= 43.02，p <.000的F统计量，总体效应大小Cohen d = 0.87，这被认为很大。与Bonferroni校正的简单对比表明，T20（M = -0.159）的分解流利程度的降低明显好于同时的对照组C20（M = -0.108，T（94）= 5.45，p = .001，p = .001，r = 0.480）。同样，对照组在5小时，C5（M = -0.050）和治疗组同时计算对比度，T5（M = -0.118，T（84）= 1.661，P = .001，P = .001，r = 0.726）。LOW和中间水平（CEFR A2-B1）日本EFL Learmers具有较高的衰减效果。与对照组相比，最长的20小时治疗组显示出分解流利度最大。所有组随着时间的推移提高了其性能，即表明，随着时间长度的增加，分解流利度的降低和速度流畅度的提高。从C5到C20的对照组也是如此。最值得注意的是，T5组与C20组显示出统计等效的改进。这是最有力的迹象表明，即时反馈，高度的互动性，进度跟踪和数字处理的整体游戏化可能是提高低对中级学习者的口语流利度的更有效方法。
