语音助手（如 Siri、小爱）是怎么听懂你说话的？
How does a voice assistant like Siri understand you?
它先把声音变成文字（语音识别），再用语言模型判断你想干什么，最后执行或回答。吵闹环境或口音会让它听错，所以有时要重复或打字。
It turns sound into text (speech recognition), then a language model figures out your intent and acts or replies. Noise or accents cause mistakes, so you may repeat or type.

什么是大模型的“训练”？
What is 'training' a large model?
训练就是让模型读海量文本，反复调整内部上万亿个参数，使它能预测下一个词。好比学生做无数道题找规律。训练很耗电、很贵，跑一次要好几周。
Training feeds a model huge text and tunes trillions of internal parameters so it predicts the next word—like a student doing endless exercises to find patterns. It's costly and takes weeks.

什么是“深伪”（deepfake），怎么辨别？
What is a 'deepfake' and how do you spot one?
深伪是用 AI 把一个人的脸或声音“换”到别人身上，做的假视频或假语音。辨别要看不自然的眨眼、模糊的边缘、奇怪的光影，以及查证消息是否来自可靠来源。
A deepfake uses AI to swap someone's face or voice onto another, faking video or audio. Spot it via unnatural blinking, blurry edges, odd lighting, and verify from trusted sources.

什么是“提示词”（prompt），为什么很重要？
What is a 'prompt' and why does it matter?
提示词是你给 AI 的指令或问题。说清楚目标、格式和例子，AI 答得更好；含糊一句它就容易跑偏。会写提示词就像会问好问题，能大大提升结果质量。
A prompt is the instruction you give AI. Clear goal, format and examples yield better answers; vague ones drift. Writing good prompts is like asking good questions—it lifts results.

为什么 AI 聊天有时会“胡说八道”（产生幻觉）？
Why does an AI chatbot sometimes 'hallucinate' false info?
大模型是按概率猜“下一个最像真的词”，并不真的查事实。它有时会编出听起来合理但不存在的书、号码或事件。所以重要内容一定要自己再核实。
A model predicts the next plausible word by probability, not by checking facts. It can invent convincing but fake books, numbers or events—so verify important claims yourself.

视频或购物 App 的推荐系统，怎么知道你喜欢什么？
How does a recommendation system know what you like?
它会记住你点过、看过、买过什么，再找和你口味相似的人喜欢的东西推给你。你看得越多，它猜得越准，但也可能把你“困”在同一种内容里。
It remembers what you click, watch and buy, then suggests what similar users liked. The more you watch, the better it guesses—but it can also trap you in the same kind of content.

智能音箱为什么有时听错你的话？
Why does a smart speaker sometimes mishear you?
背景噪音、相近的发音、或者它没听过这个词，都会让它识别错。它先把声音变文字再理解，任一步出错就答非所问。说慢一点、离近一点会好些。
Background noise, similar-sounding words or unknown terms cause errors. It converts sound to text then understands; any slip yields a wrong answer. Speak slowly and closer helps.

How does text-to-image AI art work?
它先学过海量“文字+图片”配对，知道“日落”“猫”长什么样。你描述一句话，它就从一片随机噪点里一点点“雕”出符合描述的图。结果是新的，不是简单拼贴。
It learned millions of text-image pairs, knowing what 'sunset' or 'cat' looks like. From random noise it sculpts an image matching your words—new, not just a collage.

AI 能代替老师批改作业吗？
Can AI replace a teacher in grading homework?
AI 能很快检查错别字、算数和选择题，帮老师省时间。但写作文、讲思路还是要人来判断。它更像助手，不是能完全替代老师的老师。
AI can quickly check spelling, arithmetic and multiple-choice, saving teachers time. But essays and reasoning still need a human. It's an assistant, not a full replacement.

什么是图像识别？
What is image recognition?

Image recognition lets a computer look at a picture and tell if it's a cat, a face or a traffic light. After seeing millions of labeled images, it learns patterns—used in photo sorting, scanning and self-driving.

Why is it hard to stop scrolling short videos?
推荐系统发现你爱看什么就一直推类似的，加上每条都很短、划一下就来新的，大脑容易一直想“再看一条”。这是设计出来的，定个闹钟能帮你停下。
The recommender keeps feeding similar clips, each short and instantly replaced, so the brain wants 'just one more'. It's by design—set an alarm to stop.
