2. NATURAL LANGUAGE UNDERSTANDING*
Due to natural language speech recog-
nition technology, this system recog-
nizes commands when spoken
naturally. (If the connected services
subscription has been entered, the
system will be able to connect to the
Cloud and the range of naturally spo-
ken English which can be recognized
will be increased.) However, the sys-
tem cannot recognize every variation
of each command. In some situations,
it is possible to omit the command for
the procedure and directly state the de-
sired operation. Not all voice com-
mands are displayed in the function
menu.
To use this function, a subscription to
the connected services is necessary.
Contact your Toyota dealer for details.
