Yap——macOS本地语音转文字开源应用发布

一名开发者在Hacker News上分享了新开源项目Yap，这是一款专为macOS设计的菜单栏应用，实现了无需下载模型的本地设备语音转文字功能1。该应用利用macOS 26新增的SpeechAnalyzer和SpeechTranscriber API进行语音识别1，用户只需设置快捷键便可进行语音输入，转录的文本随后直接粘贴到当前输入框1。

Yap采用MIT开源许可发布，代码完全用原生Swift编写，总计约3,000行1。应用完全在本地运行，不含任何网络代码1。在性能方面，Apple的语音模型在精度上略领先Whisper Small，同时处理速度快3倍1。从资源占用来看，应用体积仅为4 MB，空闲状态下的内存占用约60 MB1。

A developer has released Yap, an open-source macOS menu bar application that enables voice-to-text conversion entirely on users' devices without requiring model downloads 1. The tool leverages the SpeechAnalyzer and SpeechTranscriber APIs introduced in macOS 26 to perform speech recognition locally 1. After users configure a keyboard shortcut, they can dictate directly into the active input field, with transcribed text pasted automatically 1.

The application runs completely on-device with no network connectivity, ensuring privacy by design 1. Written in native Swift comprising approximately 3,000 lines of code, Yap maintains a minimal footprint at 4 MB in size and consumes roughly 60 MB of idle memory 1. According to the developer, Apple's speech recognition model achieves slightly better accuracy than Whisper Small while operating three times faster 1. The project is distributed under the MIT open-source license 1.
