alR

ALR is an acronym that can refer to several distinct terms across different domains. There is no single universal meaning, and the intended expansion is usually clear from context.

American Law Reports (ALR) is a long-standing series of legal annotations that accompany case law in the United States. Published by legal publishers and now part of larger legal information services, ALR annotations summarize and extract relevant authorities on a specific legal question, organized by topic and jurisdiction. Lawyers and judges use ALR to locate authorities and understand how courts have treated particular issues over time, often helping to identify persuasive authorities beyond primary case law.

Automatic Language Recognition (ALR) is a field within speech processing and language identification. ALR systems aim to determine the language spoken in an audio segment, using acoustic, phonetic, and statistical features. These systems support multilingual speech recognition pipelines, voice-activated assistants, and call centers, where routing or processing decisions depend on the detected language. ALR is related to, but distinct from, broader automatic language identification and speech recognition tasks, focusing specifically on language detection rather than transcription.

Other uses of ALR exist in specialized fields, organizations, or product names, where the acronym can stand for different phrases. Because the meaning is context-dependent, it is important to consult the relevant documentation or source to determine which expansion is intended in a given setting.
