Technology giant Apple has filed for a patent with US Patent and Trademark Office, for a technology that could convert text-to-speech and vice versa, Patently Apple reports.

According to the new patent, the proposed system would enable using text-to-speech and speech-to-text converters as well as providing a means of sending prerecorded notifications to the caller if you're unable to speak when answering your phone.

Also, in a situation where text messaging is needed but for some reason the system could be activated on both ends, with both speakers talking into the handset and their words being converted to text and sent to the other party, Patently Apple writes.
