L & N - I mix up L and N, so I built a pronunciation practice app

I mix up L and N myself, so I built a small app to practise the difference. I've been using it, and the listening exercises have been especially useful to me. You pick a pair like light/night, hear the examples, record yourself, and see what the speech recognizer heard alongside the score. There's also a listening test: hear a short sequence such as "light, night, light, light, night" and tap what you heard, then check each answer. It covers English, Mandarin and Cantonese.

痛点：L/N发音混淆者缺少针对最小对立对的发音对比、听辨与即时反馈练习工具。

目标用户：英语/普通话/粤语学习者，尤其是L/N不分的亚洲语言母语者、语言治疗或发音矫正需求者。

证据：I mix up L and N myself, so I built a small app to practise the difference. ... iPhone/iPad — US$0.99 ... Android — free download, with in-app purchases ... If you mix these sounds up too, is hearing the difference or saying it the harder part for you?

变现：付费下载$0.99 + Android IAP解锁更多音素对/课程；后续可做订阅制发音训练营、语言学校或言语治疗师B2B授权。

MVP：用React+TypeScript+Capacitor做移动端MVP：选择L/N等易混音素对，播放最小对立对示例，录音后调用系统语音识别并展示识别结果，加入听辨选择题和简单评分；3D口型可后续补充。

竞品：ELSA Speak、BoldVoice、Pronunroid、English Pronunciation apps、Forvo

摘要：开发者因自己L/N不分，用React/TypeScript/Capacitor做了L&N发音练习App，覆盖英语、普通话和粤语，包含3D口型、录音识别评分和听辨测试；iOS售价US$0.99，Android免费+IAP，源码公开。帖子展示了具体痛点和solo可复刻的产品形态，但没有收入数据或他人付费验证，付费意愿仍待验证。
