Patent ID: 8386166

Claim:
A navigation device for producing sounds from data, comprising: a processor; an audio reproduction device to audibly reproduce digitally processed sounds; memory, including data stored therein, said data comprising at least one of: one or more text-based indicators; and one or more pre-recorded sounds; data transfer device to transfer the data between the processor and the memory, the processor being useable to use operating system software to control processing the flow of data between the processor and the memory and to control whether the processed sounds are audibly reproduced, the processor further being useable to repeatedly determine one or more physical conditions, which are then comparable with one or more reference values provided in the memory such that satisfaction of the one or more physical conditions gives rise to an event requiring a sound to be reproduced by the second device, the processor further being useable to use a TTS software component, which interacts with the operating system software or a program executing thereon, said operating system software or program executing thereon being useable by the processor to make the determination, according to input of a user of the processor-enabled device, whether the event should be audibly identified by way of at least one of one or more pre-recorded sounds stored on the navigation device and a sound digitally rendered by the TTS component from a text-based indicator retrieved from the database and appropriate for the event; and a radio-telecommunication device to allow the navigation device to determine traffic conditions along particular sections of a thoroughfare network represented by the data and to receive messages and other information through said radio-telecommunication device.
