演示
三个词就能说出是哪种语言。
「kann ich das haben」是德语。「안녕하세요」是韩语。三个词是最难的情况，而搜索框给你的恰恰就是三个词。
只凭三个词，Tongue 得到 0.933，而一个 293 MB 的检测器只有 0.887。Tongue 只有 2 MB，分两步走：有些文字只属于一种语言，谚文就是韩语，泰文就是泰语，不用模型即可判定。其余才交给模型。
Tongue 不需要分词器、词表文件或推理运行时，整个包因此只有 2 MB。输入短到判不出来时，Tongue 会如实报告平局。
2 MB 的模型，得 0.933。
仅 2 MB，Tongue 在三个词的 FLORES-200 输入上取得 0.933，而一个 293 MB 的检测器为 0.887。
在三个公开基准上以实际发布的 int8 权重测得，其他检测器在完全相同的数据行和语言子集上运行。完整表格与失败模式见模型卡片。
应用场景
三个词就能说出是哪种语言。.
按语言路由文本
从用户输入的前几个词就选对翻译模型、分析器或客服队列，完全在设备上完成。
键盘与输入
在句子中途检测语言，切换自动纠错、联想或键盘布局，每次按键只花几十微秒。
搜索与内容管线
在索引或审核之前为短字符串标注语言，无需网络往返，也无需按请求计费的服务。
与其乱猜，不如多要几个字
「la casa」既像意大利语，也像西班牙语。Tongue 会如实报告这个平局，产品因此可以再等一个词，而不是把键盘切错。
灵感

一两个词常常是真的判不出来，再大的模型也解决不了。Tongue 这时会报告平局或一个不确定的答案，所以请把低可靠度当作「未知」，而不是一个答案。马来语和印尼语共用的词汇太多，短样本无法区分。蒙古语只覆盖传统蒙古文，因此用西里尔字母书写的蒙古语会被判成俄语。品牌名、数字和代码不属于语言，得到的只会是一个猜测。
