你有过那种「话到嘴边却懒得打」的时刻吗? Voiceboard 是一款用语音代替打字的 iOS 键盘。把想说的说出来,iPhone 会在本地把声音变成文字,让 AI 帮你把它修干净——补标点、理逻辑、调整语气——再通过系统键盘直接输入到任何 App。 适用于 iPhone 12 及以上机型,需要 iOS 26.0 或更高版本。 主要功能 端侧识别,声音不离开你的手机 英语和简体中文都支持,整个识别过程完全在你的手机上完成。音频不会上传到任何服务器,除非你主动选择把它交给 AI 润色。 接你信任的 AI(BYOK) 兼容任意 OpenAI 风格 API。你提供自己的 API Key,转录文本直连你选择的提供商:OpenAI、Mimo(小米)、DeepSeek、Anthropic、Gemini、阿里、字节、智谱、Moonshot 等任一家。Voiceboard 不内嵌任何密钥,你的 Key 存放在 iOS Keychain。 边说边翻译 中文说出来,英文输出。反过来也行。润色 + 翻译一步完成。 风格随便挑,也可以自己写 内置多种润色风格——正式、口语、简洁、扩写。觉得不够还可以写自己的 Prompt,定制你想要的语气。 iOS 26 原生 UI Liquid Glass 玻璃质感、自适应明暗壁纸、跟着声音起伏的真实音频波形。整个体验跟系统融为一体。 在任何 App 里都能用 作为系统键盘扩展,Voiceboard 在所有支持文字输入的 App 里都能调出来。容器 App 负责录音和识别,键盘负责把润色后的文字递过来。 锁屏看进度 启用 Live Activity 后,你说话的时候,锁屏和灵动岛会实时显示转写进度。 历史永远找得回 所有口述记录、润色前后的文本,都本地保存。随时翻看、复制、或重新润色。 要求 • iPhone 12 或更新机型(本地语音识别需要神经引擎) • iOS 26.0 或更高版本 • 键盘扩展打开「允许完全访问」(把润色后的文字插入到当前 App 用) • AI 润色 / 翻译需要联网,需要你自备 OpenAI 兼容服务的 API Key

Verdict
The clearest difference is in-app purchases: Voiceboard Keyboard at none against compost's 3. Voiceboard Keyboard also leads on update cadence (every 4 days vs every 5 months). compost's advantage is iOS requirement (16.2 vs 26.0). On price, ads and device support there is nothing between them.
