Voice is not first-class until it understands intent.
Voice is often called an interface when it is really being used as a faster keyboard. You speak a paragraph, the computer types it, and the cursor moves on. The interaction is quicker, but the person still has to arrive with a finished thought and supervise the machine word by word.
Commands create the same illusion. “Open the plan” works only when there is one obvious plan and one obvious action. Real work sounds more like, “Send Molly the version we agreed on yesterday, but leave out the pricing change until I have spoken to her.” Every important word depends on something outside the sentence.
To understand that request, the computer has to follow the conversation behind it. It needs to know which Molly the person means, which draft survived yesterday's discussion, whether “her” still refers to Molly, and whether the pricing change was rejected or merely withheld. It also has to recognize the boundary inside the request: prepare one version now, preserve another decision for later.
The example reveals why intent is not a speech-recognition problem. Yesterday's discussion has to survive long enough for Candor to find the moment the team settled on a draft, connect it to Molly, and judge whether the speaker has authority to send it. At work, no single person necessarily holds that entire history. The words become useful only when those scattered pieces can be understood together.
The same words can also carry different intent depending on how they are spoken to the system. While dictating, the person may be composing the message to Molly. Asked as a question, the sentence may be a request to explain which version survived. Spoken while thinking aloud, it may require no response at all. A request to send the message crosses another boundary again. Until the interface can tell those moments apart, it understands the sentence but not the person.
Uncertainty is part of understanding, not evidence that the interface failed. If yesterday's meeting never settled which version to send, the intelligent response is a question. If the speaker lacks the authority to withhold the pricing change, the system cannot manufacture that authority from a confident tone. Knowing when not to proceed is part of knowing what someone intends.
The user should not have to think about those layers. They speak as they would to a capable colleague, with references, corrections, and unfinished thoughts intact. If the machine requires them to reconstruct the context and translate the request into exact commands, voice is still only decorating the old interface.
Recognition turns sound into words. Intent turns words into work.
