IELTS Speaking Coach
AI辅助雅思口语1v1陪练系统，100天从5.5分跳到6.5分。
AI-assisted IELTS speaking 1-on-1 coaching system, from 5.5 to 6.5 in 100 days.
痛点
THE PROBLEM
雅思口语高度依赖老师逐条听录音、逐条反馈，单个学员服务成本高。一个老师最多服务10个学员，难以扩容。学员付费意愿强（刚需考试），但缺乏性价比高的陪练方案。
IELTS speaking heavily depends on teachers listening to and grading recordings one by one. High per-student cost limits one teacher to ~10 students. Students are willing to pay (exam pressure) but lack cost-effective coaching options.
解决方案
THE SOLUTION
用AI承担高频重复工作（语音转写、初步批改、任务派发），老师专注高价值环节（诊断、审核、个性化指导）。让1个老师服务50个学员，审核时间从30分钟压缩到5分钟。
Let AI handle repetitive work (transcription, initial grading, task assignment) while teachers focus on high-value tasks (diagnosis, review, personalized guidance). One teacher serves 50 students, review time from 30 to 5 minutes.
