The Sound Lab — how Shanghainese pronunciation actually works: 26 initials, 22 finals, 5 tones, and the tone-sandhi rules that tie them together. Every Chinese module below stays in Chinese; the italic English notes tell you what each one does.

"沪语的语法骨架，是一张调表。"
五个模块从感知（旋律/爆破/震动）到算法（变调过山车）再到综合实战。
变调计算器是这一层的"心脏"——输入任意词，按规则实时变调、可视化曲线、合成音收听。
其余模块本期为框架级，留出真人录音与扩展的接口。
"The grammar of Shanghainese rests on a tone table." The five modules move from perception (melody, burst, voicing) to algorithm (the sandhi coaster) and finally to integrated practice. The sandhi calculator is the heart of this level — type any word and watch its tones bend in real time, with curves and synthesized audio.
声调旋律
FIVE TONES AS MELODY
5 个声调 = 5 段旋律。配英语参照句、情感场景、例词矩阵。
The five tones as five melodies — with English reference sentences, emotion scenes and example-word matrices.
入声爆破
CHECKED-TONE BURST
"book / bit" → 屋 / 一 的掐断动画；按韵尾分类的入声字矩阵。
Feel how checked syllables get cut short — like "book" and "bit" stopping abruptly — sorted by final consonant.
浊音震动
VOICED-CONSONANT TREMOR
手指按住喉结的体感教学；9 对清浊声母对比；人称代词实战场。
Touch your throat to feel voicing; nine voiced/unvoiced initial pairs plus a pronoun practice field.
变调过山车 · 计算器
TONE SANDHI CALCULATOR
输入任意 2 字 / 3 字词，按变调表实时计算 + 曲线可视化 + 合成调型音。三级词库与易错陷阱。
The star tool: type any 2–3 character word, get live sandhi results, pitch curves and synthesized audio. Three word lists plus common traps.
