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。

Hi HN! I'm Sheryl, founder of Altura ( https://www.altura.coach ). I've been a tech executive for close to 30 years. I'd worked on my communication throughout my career. I read books, take courses, put effort in every important meeting, but the progress was terribly slow. Then I read a transcript of myself in a job interview, filler words ("you know", "like") burst in clusters throughout the meeting. I had no idea that I was saying them.
