识别

• Pinyin: shí bié
• Hanzi breakdown: 识 = 讠+ 只 (know, recognise, awareness); 别 = 口 + 刀 (distinguish, separate, differentiate)

Meaning

To identify; to recognise; to distinguish. The process of detecting and classifying objects, people, or signals.

Widely used in technology, security, and scientific contexts. Core term in AI and biometrics: 人脸识别 (facial recognition), 语音识别 (speech recognition), 指纹识别 (fingerprint identification). Also used in biology (物种识别 — species identification) and military/intelligence contexts (目标识别 — target identification). Implies a systematic, deliberate process of differentiation rather than casual recognition.

Examples

1. 人脸识别技术在安防领域的大规模应用，引发了公众对个人隐私保护与数据安全的广泛讨论。 The large-scale use of facial recognition technology in security has sparked widespread public debate about personal privacy and data security.
2. 该平台采用先进的人工智能算法，能够精确识别并分类海量图片中的植物物种与生态特征。 Using advanced AI algorithms, the platform can accurately identify and classify plant species and ecological features across massive collections of images.
3. 边境管理部门通过生物特征识别系统对入境旅客进行核验，大幅提升了通关效率与安全水平。 Border authorities verify arriving travelers through a biometric identification system, greatly improving clearance efficiency and security.

Do Say

• 这套自动识别系统能够在毫秒级别的时间内完成对车牌号码的精确读取，并实时与违规车辆数据库进行比对核查。(This automated recognition system can complete precise reading of licence plate numbers within milliseconds and perform real-time cross-checking against the database of non-compliant vehicles.)
• 研究人员开发出一种新型算法，可以从复杂背景噪声中识别出特定目标的声纹特征，识别准确率在标准测试条件下超过百分之九十八。(Researchers have developed a new algorithm capable of identifying the voiceprint characteristics of specific targets from complex background noise, with a recognition accuracy rate exceeding 98% under standard test conditions.)

Don't Say

• 识别 as a synonym for 认识 (to know someone) or 认出 (to recognise a person by sight) in interpersonal contexts — 识别 implies a systematic identification process, not simply recognising a familiar face or recalling a memory
