A user of a wireless device, such as a mobile phone, can make purchases or obtain
information via a network, such as the Internet, using both voice and non-verbal
methods. Users can submit voice queries and receive non-verbal replies, submit
non-verbal queries and receive voice replies, or perform similar operations that
marry the voice and data capabilities of modern mobile communication devices. The
user may provide notification criteria indicating under what conditions a notification
should be sent to the user's wireless device. When purchasing opportunities matching
the selected notification criteria become available, the user is notified. The
user can respond to the notification, and immediately take advantage of the purchasing
opportunity if he so desires. Mixed-mode interactions can also be used by sellers
to more advantageously control the marketing of distressed, time sensitive, or
other merchandise/services.
