HowToWhistle：像唱 KTV 一样练习吹口哨 一直想提高吹口哨技巧，搜了一圈发现网上的教程都是文字和视频，练的时候根本不知道自己吹得对不对。 想到可以像 KTV 一样，有个音轨对比，于是干脆自己搓了一个练习网站：[https://howtowhistle.org/]( https://howtowhistle.org/) 核心思路是用浏览器的麦克风做实时音高检测，你对着麦克风吹，页面会显示你当前的音高和目标音的偏差，类似 KTV 唱歌时的实时评分。功能大概有： - 实时音高反馈，能看到自己吹的是哪个音、偏高还是偏低 - 从单音长音开始的渐进式练习，到音阶、再到简单旋律 - 纯前端实现，声音不上传，无需注册 目前还比较简陋，欢迎大家试玩和提建议。

I am getting laid off, so I built a free AI interview coach that scores how you speak. I need your brutal feedback I've spent 9 years breaking things and have worked as a QA Analyst, QA Engineer, and Software Development Engineer in Test. Just found out I'm being let go. Instead of browsing job boards, I built something I needed for my interviews. I tried many prep tools, and they all check your answers. But almost none look at how you deliver them, the rambling, filler words, or answers th

I built an AI that makes you funnier, looking for 10 testers full disclosure: I'm not a standup. just a guy who always wanted to be funnier in real life and figured reading about comedy does nothing, you need reps. but bombing in front of real humans is terrifying, so I built the next best thing: an AI crowd that reacts to your bit while you perform it, plus a judge that scores you and points out where it stopped working. there's a daily challenge so you get a rep in every day.

Users spar with ai to overcome objections, practice their pitch, and get in reps before a real deal is on the table. Once a spar session is complete a course is created on users weakness to help them improve.

做了一个免费的声音表达分析工具，录 5–15 秒就能看到反馈 最近做了一个小工具：Voice Impression Checker 。 它想解决的问题很简单：我们经常知道自己“说了什么”，却不太清楚这段话听起来是什么感觉。 打开网站后，只需要录制 5–15 秒自然说话的声音，工具会从这一次录音中分析： - 清晰度、语速、稳定性、能量和声音变化 - 听感上的温暖、自信、亲和力和参与感 - 这次表达做得比较好的地方 - 下一次录音可以尝试改进的一件事 网站还提供了 Rate My Voice 模式，可以针对面试回答、演讲开场、自我介绍和日常交流等场景进行练习。 需要特别说明的是，它不是声音好坏评判，也不会通过声音判断性格或身份。所有结果只描述当前这一次录音的表达效果，更适合用来反复练习和比较不同说法。 目前网站免费使用，不需要注册账号，录音仅用于生成当前报告，不会保存。 网站地址： https://voiceimpressionchecker.com/ 这是一个刚完成的早期版本。如果你愿意体验，欢迎告诉我结果是否容易理解，以及你最希望
