空气小猪,是全球首款基于熟人社交场景打造的语言习得AI系统。用户只需母语表达,系统即刻将其精准翻译为目标语言并自动朗读,在真实社交中实现“无痛输入”。语音输出自然流畅,情感语调逼真,朗读速度可调节,初学者也能轻松理解、主动参与。相比传统的背单词、死记硬背,空气小猪通过日常聊天,将语言学习潜移默化地嵌入每一次互动之中。 系统支持英语、法语、日语、西班牙语、德语等全球主流语言,真正做到“语言自由切换,表达无障碍”。Memo词卡系统会自动捕捉对话中用户的薄弱表达,结合上下文形成个性化词卡,通过语境复现与结构分类,引导用户进行深度学习。成长树机制让语言掌握过程可视化——词汇掌握程度、表达搭配熟练度、语法结构积累路径,一目了然。 不再强迫,不需自律,每一次沟通都是一次“语言成长”。空气小猪不教语言,它让语言在你身边自然长出来。就像树一样,扎根于你的生活,开花在你的表达。
