正音 ZhSound —— 專為香港人而設的普通話發音教練。 香港人講普通話，最大的關口是「發音走音」而不是詞彙。正音幫你把每個音練準： • 錄音對比：錄下自己的發音，跟標準示範 A/B 對比，一聽就知差在哪。 • 彩色拼音：貼上任何中文，即時逐字標出聲調顏色的拼音；可顯示「三聲變調」的實際讀法。 • 聲調評分：錄音分析你的音高，即時回饋聲調對錯。 • 主題詞庫：日常、商務普通話、情景對話、唐詩、成語、網絡潮語，過千詞語，每個可聽、可練、可收藏。 • 發音難點：針對廣東話人士難讀的翹舌音、平舌音、ü、前後鼻音、兒化等，逐類攻破。 • 錯題本 + 間隔重複：自動收集讀錯的字，用 FSRS 安排複習，練到記得住。 完全在裝置上運行，不需帳戶、不需登入、離線可用；不收集你的資料。
