About

LISU

Features
Read full description

Lisu language, also known as Biblical script and Fu Neng Ren script, is a script that imitates the Latin alphabet and is specially used to record Lisu language. The Lisu people have their own language and writing, but because the Lisu people live scattered, there are many dialects. However, the translation of the Lisu Bible is basically universal except for the difficult context. This dictionary contains more than 10,500 phrases and is constantly increasing. Starting from v4.0, English definitions are officially added, making it a Lisu × Chinese × English trilingual dictionary. It aims to develop an easy-to-use tool that can better preserve the Lisu language and help people learn more Lisu, Chinese, and English vocabulary. [Completely rebuilt in v4.0] * Bilingual Chinese & English Definitions 10,500+ entries now include both Chinese and English translations. Every word card shows Lisu, Chinese, and English side by side — trilingual comparison at a glance. * Dual-Language TTS Tap Chinese text to hear it spoken in Chinese, tap English text to hear it spoken in English. Read what you hear — each language plays its own voice. Text auto-enlarges and bounces during playback, so you see and hear in sync. * Trilingual Search Search in Lisu, Chinese, or English. Whatever language you type, results show definitions in that language below. Intuitive and fast. [Carried forward from previous versions] * Pronunciation Table Built-in 222 standard tone recordings covering all Lisu syllable combinations. A dual-scroll grid that you can tap to zoom and play instantly, helping you quickly master correct pronunciation. * Pronunciation Reference Every word card can play full pronunciation with one tap. The currently-sounding character auto-enlarges, bounces, and turns gold so you can see and hear in sync for more precise pronunciation. Pronunciation is for reference only and may vary by region. Please follow your local dialect conventions. This tool is solely for cultural preservation and learning.
