by using Text-To-Speech to address the user by name or provide
specific information based on their profile or history. Some common
types of personalised voice prompts are name, profile, context,
location, activity, preference, and mood.
• For example, the prompt for the name attribute could be “Hi [name],
this is a reminder about your appointment tomorrow,” while the value
for the appointment time attribute could be “Your appointment is at
