when interfaced with VTS forms an intelligent Advanced Driver Assistance System’s audio unit. The events and alarms detected by the VTS device will be given to voice box to play respective audio message. This is ‘Event message announcement’ device, specifically designed to be used in ‘Advanced Driver Assistance System’ (ADAS). The unit stores audio messages relevant to vehicle driver in the internal memory, and plays back specific audio file for given event.
The Audio Unit plays pre-recorded audio messages on receiving voice code. This OTA model has a facility to write new audio files in the internal memory via RS232 port. The RS232 port is always connected to VTS, meaning VTS can upload new audio files in Voice Box at any time. To play back the audio message, the interfacing unit (here VTS) will send a predefined ‘Voice code’ over serial RS232 port, Audio Unit will search appropriate message to be played and trigger audio circuits. Presently audio Unit can store in-all 160 messages (96KB each). The maximum file size and number of files can be altered as per customer requirement. The voice code is predefined and standardized with VTS manufacturer for ease of interfacing. After detecting event or alarm condition VTS will send any one of the voice codes to VTS over RS232 port at 57600 baud. Audio unit all the time monitors port activity. The received voice codes are placed in a queue for playing messages one after other. Audio unit implements a message queue of voice codes for 10 voice commands. Audio unit will play all audio messages in sequence of the received messages.
Voice Box optimizes the balance between deep, flexible functionality and safety. Because drivers don’t have to ‘think about’ how to structure a command, they are less distracted. And independent research shows that consumers prefer Voice Box to other solution The Voice Box Unit is the record and playback unit, which will play the voices as per need. Majorly this unit is used in the logistic fields, and many official fields where a frequent guidance in the form of voice is needed
