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。

PracticeTherapy.ai: free training simulator for therapists practicing with simulated clients Hi reddit, I launched PracticeTherapy.ai (ask for invite code, YouTube demo ) It's a deliberate practice platform for mental health professionals (therapists, social workers, psychologists, etc) to learn new clinical skills. Here's how it works The goal is to help clinicians develop practical instincts in simulated sessions that can transfer into real client work. Learn

Got tired of being so damn slow at writing, built an app to fix it I built this over a summer, which is a sentence I used to write about other things. I'm a physics student and a sailing instructor, I don't code, and I used an AI so I wouldn't have to learn — which, God help me, is the most honest thing I've said in this whole post. 31 sub-levels. It tracks the letters I get wrong and the specific pairs of letters I get wrong, which is more self-awareness than I've managed in a decade. Free

做了一个无需注册就能试的方言配音工具「乡音阁」，想请 V 友帮忙体验 大家好，我之前一直主要做开发，产品做出来后不太擅长推广。这次想把自己长期维护的一个项目发出来，请大家体验一下。 项目叫「乡音阁」，是一个中文方言文字转语音工具。 做它的原因比较简单：普通话配音工具已经很多，但粤语、四川话、东北话、闽南语等方言的选择相对有限。 目前已经支持： - 10+ 种中文方言和多种音色 - 输入文字生成方言语音 - 在线试听和下载音频 - 声音复刻、声音设计和 API - 中英文页面 体验地址： https://xiangyinge.com/zh 无需注册可以直接试用 100 个字符；超过免费额度后需要购买资源包。 如果愿意体验，我比较希望了解： - 使用了什么方言和音色 - 哪些字词发音不准确或不自然 - 操作过程中是否有不清楚的地方 - 你希望用它解决什么问题 产品目前主要由我自己开发和维护，前端使用 Next.js ，部署在 Cloudflare 。技术实现、产品设计或者推广方面的问题也欢迎交流。 感谢大家体验

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
