Is a dictated trip saved without my confirmation?

No. Nothing enters your list without a click from you: the assistant proposes, you confirm.

1. After your sentence, the assistant shows a box headed 1 trajet prêt à ajouter, or N trajets prêts à ajouter, with each line it understood.
2. If everything is right, click Ajouter ce trajet or Ajouter ces N trajets.
3. Otherwise, click Non, reformuler: the proposal disappears and you add what was missing.
4. To start over, click Nouvelle conversation.

Once added, a dictated trip is edited like any other: departure, arrival, vehicle, purpose, round trip or exclusion, directly in the trip list.

The assistant is only there to record your trips: it does not answer general questions and never modifies an existing trip. This strict scope is what makes it reliable.
