	In a human-machine interaction, '''mixed-initiative''' could be also considered as an alternation of flow-control initiative during time. By example let's consider an home automation voice assistant. The initiative could be triggered by a question or command that user ask to the conversational system.

''The system initiates, and closely directs, all interaction. Most systems deployed thus far used a directed-dialog strategy. A directed dialog fora travel planning might sound like this:''

<code>System: What's the departure city?</code>

<code>Caller: Um, San Francisco</code>

<code>System: And the arrival city?</code>

<code>Caller: I wanna go to New York</code>

<code>System Ok, what day you are living?</code>

<code>Caller: Next Tuesday</code>

<code>System: Great. And what time do you want to go?</code>

<code>Caller: Sometime after ten a.m.</code>

''This directed-dialog is an example of form-filling. The caller is asked a series of directed questions as is the caller were filling out a form.''

''With a mixed-initiative dialog strategy, the same travel dialog might allow callers more flexibility in what they can say. First the initiative come from the caller. Depending on the caller's response, the system may then take initiative and prompt for missing information:''

<code>System: What are travel plans?</code>

<code>Caller: I wanna go to New York next Tuesday morning.</code>

<code>System: Ok, and what's the departure city?</code>

''In this second example, the caller provides several pieces of information for the trip, and then the system takes the initiative and prompts for the rest. All mixed-initiative dialogs need to include back-off strategies to capture missing pieces of information.''<ref>froem pages 63-64 of book Voce User Interface Design, by Choen, Giangola, Balogh. 2004</ref>
