Abstract

A vehicle-mounted apparatus is capable of recording customized voice road feature descriptions along with location information as the vehicle travels along the road. A vehicle location signal generating device is associated with the vehicle and is capable of producing a vehicle location signal in response to an audio input signal initiated by the device operator. When an audio input signal is entered, a processor generates a unique event sequence indicator for each audio input signal. Each event sequence indicator is unique to the particular audio input signal for which it is produced and indicates the order in which the respective audio input signal is produced in relation to any other audio input signals. An audio sequence generating device synthesizes an audio sequence signal for each event sequence indicator and this audio sequence signal is recorded in an audio recording device along with a custom feature description dictated by the device operator. In addition to the recorded audio information, a data storage device records each event sequence indicator and the vehicle location signals. This information may then be combined with the recorded audio information using matching event sequence indicators to produce a complete road feature record.
