Use case
Innovative travel consultation with a speech-to-speech agent
In conversation
What the real-time voicebot can do
A caller contacts the travel consultation service because she needs an extra suitcase for her upcoming trip to Japan. During the conversation, several issues come up at once:
A speech-to-speech agent takes over the consultation and handles all three issues in the same conversation. The following three steps demonstrate how this works in detail.

Part 1
Listening, understanding, and reacting
The caller would like to book an additional piece of luggage for her trip to Japan. The agent asks her for her date of birth – but in the middle of the conversation, she remembers something else and jumps to two new topics before providing the information.
Shortly afterward, the caller provides the information – the agent confirms her identity and continues with the original request.

Part 2
Completing tasks and switching languages
While the additional piece of luggage is being entered into the system in the background, the conversation continues as usual: The caller asks about import regulations for food items she would like to bring with her – and spontaneously requests an answer in Japanese.

Part 3
Resolving or handing over seamlessly
Finally, the agent brings up the third issue on its own – one that the caller had only mentioned in passing at the very beginning: a possible trip in the fall.
The conversation ends without any of the three concerns being overlooked.
