2. Processing data through AI and language technology

After receiving, the information is sent to data processing systems, including:

- Natural language processing (NLP): Technology helps the virtual assistant understand the meaning of the sentence, regardless of how the user expresses it.

- Dialogue Management: The system determines the user's purpose and provides appropriate responses.

- Text-to-speech (TTS): If the response needs to be delivered in audio, the virtual assistant will convert the data into a natural voice.

- Data retrieval or transfer: If the question is out of the scope of the scenario, the virtual assistant will search for the answer from the internet or forward it to a support staff to ensure the user experience is not interrupted.

3. User feedback

After processing, the virtual assistant will respond via:

• Text: Respond on the screen.
• Voice: Play audio feedback.
• Image: Displays charts, maps or appropriate visual interfaces.
