Starting A Voice Session

To start a voice session the driver must press the voice button briefly. An audible tone can be heard, followed by the presentation of the voice command menu list in the SWYS pop-up in the TSD. A voice symbol alongside each item in the list indicates that the system is listening for one of the available commands. Always wait for the listening tone before using the command. To end the voice session press and hold the voice button.

When the voice button is pressed on the steering wheel, a voltage signal is received by the TSD via the clockspring. The voltage is sent on a single wire through a resistive ladder. The voice system activation is processed on the MOST ring, for example the voice menu list is retained in and presented by the TSD. The accompanying voice instruction is sent to the audio power amplifier from the IAM on the MOST ring for broadcast over the vehicle speakers. When a recognized user instruction is received by the IAM via the microphone, the instruction is processed by the IAM and sent to the TSD to perform the required action.
