随课背单词,是一款围绕真实教学进度建立专属词库的英语学习工具。 学校发什么,就重点学什么。 很多背单词软件只能使用平台预设词库,但不同学校、不同教材、不同班级,甚至每个单元的重点词汇都可能不同。随课背单词允许学生、家长和教师根据学业指导、课堂资料、阅读内容和考试范围,建立真正贴合当前学习任务的词库。 【从学校资料快速建立词库】 支持从学业指导、单词表和课堂资料照片中识别英文词汇,也可以导入文本和表格文件,或进行手动补充。 识别结果不会直接进入正式词库,而是先进入待确认列表。你可以检查英文、中文释义、词性、词汇类型、单元和来源,批量确认后再加入词库。 系统会自动提示重复词,避免同一个单词被反复录入。只有英文而没有中文释义的词条,也可以在家长允许后补充中文意思和词性。 【词库跟着教材和学习进度走】 每个单词都可以记录: · 中文释义与词性 · 三会词、四会词、阅读词等学习要求 · 年级、学期、单元和词汇来源 · 懂意思、会拼写、会读三项独立掌握状态 · 答题次数、错误次数和当前生疏度 特别适合以下场景: · 学校每周或每单元发放新的学业指导 · 教材或校本课程不在普通背单词软件的预设词库中 · 家长希望整理日常阅读和辅导中遇到的新词 · 考试前需要按照指定范围集中复习 · 教师或同班家长需要通过词库文件互传整理成果 · 需要在电脑上用 Excel 批量整理,再导入 iPad 学习 【三项能力分别练习】 认识一个词,不代表能够正确拼写或朗读。 随课背单词把每个词拆分为三项能力: · 懂意思:看到英文后先独立回想中文意思,再显示答案并进行自我判断 · 会拼写:根据中文和词性提示输入英文,答错后显示正确拼写 · 会读:播放标准英文发音,学生跟读后进行自我判断 三项能力分别记录进度,可以自由切换练习顺序,只有本场安排的三项任务全部完成,练习才算结束。 【根据掌握情况动态复习】 每个单词和每项能力都有独立的生疏度。 答错的词会提高复习优先级,并在当天稍后、下一场或接下来的学习日再次出现;连续答对后,复习间隔会逐渐拉长。已经掌握的词不会毫无必要地反复出现,但经过较长时间后仍会安排抽查。 学习计划不是一张固定不变的任务表。系统会根据剩余词量、错误情况、掌握程度和剩余天数,动态估算每天需要完成的词量。 支持每天学习一次或分为早晚两场,也可以定期安排错题专项日,集中降低易错词的生疏度。 【不同目标,分别保存进度】 可以为不同教材、考试或词汇范围建立多个学习计划,并自定义计划名称。 每个计划独立保存学习进度、完成度和宠物成长状态。切换计划不会清除已经完成的记录,调整计划也不会让已经学过的内容重新变成未学习。 【让坚持学习更有反馈】 练习过程配有可命名、可切换的成长宠物。 随着计划推进和薄弱词逐渐掌握,宠物会获得成长。开始练习、连续答对、遇到错题和完成练习时,宠物会通过动作和对话给予适当反馈,让每天的学习过程更有陪伴感。 【词库保存在自己的设备中】 词库、学习记录和个人设置默认保存在本机。用户可以主动导出完整备份,也可以选择保存到自己的 iCloud 私有空间,用于更换设备或重新安装后的恢复。 随课背单词适合希望让英语学习真正贴合学校进度、教材内容和个人薄弱点的学生、家长与教师。

InstantSpeech is an AI oral-expression coach that helps you practice eloquence, public speaking, and Mandarin pronunciation. Rambling? Too many filler words? Speaking too fast? Record once, and the AI pinpoints exactly what to improve. Practice before an interview, a presentation, or a speech — and speak with confidence. How it works Record and transcribe: your speech becomes text instantly, ready for review Expression analytics: speech rate, pauses, filler words (um/ah), and vocabulary richness, computed automatically AI Coach: deep analysis of logic and recurring habits, with actionable tips Practice reports: every session is saved, so you can track your progress iCloud sync: your records flow across your devices Who it's for Job interviews: self-introductions, mock Q&A Workplace: reviews, meetings, pitches Public speaking: speeches, impromptu talks, contest prep Mandarin and English practice: pronunciation, reading aloud, tongue twisters Privacy and security Audio recordings are saved on your device and excluded from iCloud backup; when cloud transcription is used, audio chunks are uploaded over HTTPS solely to generate text in real time and are never retained AI analysis sends text only (no audio); nothing is stored on the server, and all traffic is HTTPS-encrypted No ads. No collection of your name, contacts, location, or other personal data Subscription The free version covers recording, transcription, and basic analytics (30 minutes per session, 5 sessions per day, 3 AI coaching sessions per month). InstantSpeech Pro (monthly subscription) unlocks unlimited recording time, 200 AI coaching sessions per month, and all advanced features. The subscription renews monthly automatically, and payment is charged to your Apple ID at confirmation of purchase.
