A link, called an X-Link~ and is placed in a message (SMS, MMS, email etc ) that is sent to a user and displayed on their device (e.g. mobile telephon e). When the link is selecte'd by the user, it connects the user's device to a conversion system, enabling the user to speak a reply which is then conve rted to a text based reply message; the reply message is then sent to the or iginal message sender (and/or another appropriate recipient). This approach enables a text message to be responded to by voice: it is an example of an a symmetric communication. There are many circumstances where this approach is very useful - for example if the message is a SMS and the recipient does no t know how to respond using SMS, or is in an environment where it is difficu lt (perhaps when walking or driving). |
