From speech to a useful action.
A simple architecture for turning a conversation into something an application can safely do.
Humlet editorialA spoken request can contain everything an application needs: a task, a name, a quantity, a date. Turning that request into useful work takes more than producing a transcript.
The system needs to understand the message, identify the relevant details, confirm the intended action, and check whether the action actually succeeded.
Capture what was said.
Start with the original speech and a transcript that preserves meaningful details. If the workflow includes translation, keep the source and translated text connected. Names, numbers, corrections, and conditions should remain easy to review.
A polished summary is not a substitute for this record. If the next stage gets a quantity wrong, you need a way to determine where the error entered the workflow.
Extract a proposal, not a completed action.
Imagine a request to move a delivery from Tuesday to Thursday. The application can extract the requested change and identify the order, but it still needs to check that the speaker has the relevant authority and that the new date is available.
Treat extracted values as a proposed input to the business workflow. Missing or ambiguous details should remain unresolved until clarified. Do not fill them in simply because the destination form requires a value.
Confirm the details that matter.
Read back the meaningful change in a short, clear form. Give the person a chance to correct it before the application makes the change. The confirmation should reflect the final request, including any correction made during the conversation.
Different actions require different safeguards. A note draft can remain editable; a change to an order needs the application’s normal checks. The speech layer should not bypass the rules already protecting the underlying system.
Verify the result before announcing success.
After the application submits the action, it needs to inspect the response and handle failures. A timeout or rejected request should not produce a cheerful spoken confirmation that the work is complete.
Humlet’s role in this architecture is the speech layer: the direction is easier access to recognition and translation while the application owns its workflow and permissions. Keeping those responsibilities clear makes integrations easier to reason about and errors easier to recover from.
Hearing a request, understanding it, and completing it are separate steps worth making visible.
