Channels and talkgroups do more than separate traffic. A working radio plan assigns functions, audiences, authority, and fallback paths for a defined period.
A radio does not carry a voice intact. It turns speech into a sequence of constrained decisions about access, bandwidth, coding, timing and reconstruction. Understanding that chain explains why a message can sound clear yet lose the one word that matters.
A radio corpus is a sample of work, people and signal paths. Define its population, preserve the original recordings, and keep related sessions together through evaluation.
A short acknowledgement can mark receipt, understanding, intention, or compliance. Those states are different, and safety-critical systems make the difference explicit.
A transcript can preserve every spoken word and still lose the shared context, correction, and uncertainty that made the exchange intelligible.
A credible radio ASR evaluation needs more than one word error rate: it must expose critical-word failures, invented speech, data leakage, and runtime behavior on the actual device.
We connect primary research and technical standards to the realities of spoken work. Published findings, our interpretations and proposed experiments are identified separately. These articles report no new Memo field trials or model benchmarks.
