1. A method for operating of a dialog system, the method comprising: activating, by means of a computing device comprising one or more processors and a memory, a speech acquiring mode; receiving, by means of the computing device and via the speech acquiring mode after the activating, a first input of a user; deactivating, by means of the computing device and after receiving the first input of the user, the speech acquiring mode; obtaining, by means of the computing device, a first response associated with the first input; delivering, by means of the computing device, the first response to the user; determining, by means of the computing device, that a conversation mode is activated, wherein determining that the conversation mode is activated is based on prior input provided by the user via a user interface, the prior input provided prior to receiving the first input of the user; selecting, by means of the computing device and after obtaining the first response, a first predetermined time period based on a conversational length of the first response; and based on the determination that the conversation mode is activated, automatically re-activating, by means of the computing device, the speech acquiring mode within the first predetermined time period after delivery of the first response to the user; receiving, by means of the computing device and via the speech acquiring mode, a second input of the user after the reactivating; processing the second input, using an automatic speech recognizer, to generate a recognized input.
