课堂难点
Where notes fall short
有录音
不等于有证据
A recording is only the start
of checking what was said
老师讲到重点和考点时，信息往往连续出现，笔记很难同时跟上。录音能留下现场，但噪声、距离和多人说话也可能让转写漏字或偏离原话。
When a teacher reaches a key point or exam cue, information can arrive faster than notes can keep up. A recording keeps the moment, but noise, distance, and overlapping voices can still pull a transcript away from the original words.
课溯先把原始录音留下，再在本机完成转写。整理重点时，用课程材料和专业词库校对；想确认时，点回时间点听原音。
VeriLecture keeps the original recording and transcribes it on the device. Course material and subject terms help check the points; when something is unclear, jump back to the timestamp and listen.
