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

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

通过实时音准反馈和渐进式练习学习吹口哨。
x1shir · V2EX
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。

将文本转为自然音质AI语音,支持18种语言,无需注册即可下载MP3。
