Dialog Management means = deciding what to do next.

But something else makes Voice AI feel human instead of robotic:

Context and Memory Management

Consider this exchange:
๐Ÿ—ฃ๏ธ โ€œBook me a flight to Paris.โ€
๐Ÿ—ฃ๏ธ โ€œMake it business class.โ€
That second sentence only makes sense if the system remembers the first.
Thatโ€™s context.

This information feeds directly into Dialog Management so the system can make better decisions.

Without memory, every interaction would feel like the first one.

LLMs can reason โ€” but the architecture decides what to remember, when to retrieve it, and when to forget.

That balance is what makes Voice AI feel natural and safe.
