F01 Voice Activation System
Introduction
History
Voice-activated control was offered for the first time as an option for the E38. The sys-
tem enabled the driver to operate the telephone and the navigation system without tak-
ing his or her eyes off the road and the traffic situation.
As the voice recognition system evolved, the number of spoken command the system
could recognize increased by leaps and bounds from the initial 30 to the current figure of
about 470 (CCC with the Voice Activation option in the E60, E90). This means that in
the current models, voice control can be used not only for the telephone and the navi-
gation system, but also for entertainment, the address book, the air-conditioning func-
tions and vehicle individualization settings.
Voice Activation is standard equipment on the F01/F02 and it is always combined with
the Navigation System .
Note: The Voice Activation System and the Navigation System
are both standard on the F01/F02.

F01 Voice Activation System
The Voice Activation system has been further enhanced.
There is now an even larger range of spoken commands and for the first time the user
has the option of individualizing the voice recognition system in accordance with specific
needs and preferences. For example, users can match the voice recognition system to
their own knowledge base and use the controller to change the spoken-language setting.
Other innovations of the voice activation system include:
" Visual feedback in the instrument panel.
" No audible beep signal during a dialog with the system.
" Combined mode with both voice inputs and controller inputs.
" Intersections and zip codes can be entered as destinations.
" Voice control of contacts, phone book and address book with up to 3000 entries.

F01 Voice Activation System
System Overview
The following pages show the input/outputs and the schematic circuit diagrams of the
F01/ F02 voice input and activation systems.
The driver s side microphone is the only device used for voice input.
Voice input is always activated by pressing the PTT button (push-to-talk button) on the
steering wheel.
The control units, sensors, control elements and components involved in the system are
shown in the input/output diagrams. A block diagram representation of a specific control
unit is additionally shown.
The input/output diagram provides an overview of the system in the form of a signal flow
diagram. It does not indicate whether the signals are sent via busses, other control units,
hard wiring or by wireless means. This detailed information can be found in the schemat-
ic circuit diagram.
The graphic representation is always followed by the corresponding legend which can
be found either under the graphic or on the next page.
For the sake of clarity the various individual speakers are not shown in the schematic cir-
cuit diagrams.

The voice input function is always implemented in the CIC.
The DVD changer serves as an example of the other voice-activated systems
that can be controlled.
The wheel speed signals are used for speed- dependent volume control.
Volume can be adjusted by means of the multifunction steering wheel and the IHKA/
audio control unit. Speed-related volume control is also active.
The microphone is connected to the TCU and the telephone commands are processed
by the telephone control unit and made available on the MOST bus.

System Functions
What can be operated by voice input?
In the F01/F02, broadly speaking all the menus that can be viewed in the CID can be
voice-controlled to the second level of a menu.
The graphic below shows the first level of the Navigation menu on the left, and the
second level on the right.
Direct entry to the first level of the menu is a possibility for reducing the length of
operating time needed to activate a particular function. This is done by saying aloud a
term from the menu in question. Instead of having to say first "Navigation" and then
"Destination entry", the user can simply say "Destination entry" to go directly to this
function. The command is executed regardless of which menu is currently open.

F01 Voice Activation System
Standard and Short Dialogs
Until now, all voice recognition systems have suffered from the drawback of appearing
complicated to inexperienced users (beginners). The difficulties were due to the fact that
the user was unaware of how many voice commands were available, or failed to enunciate
the commands correctly and completely.
Experienced users (experts) on the other hand, had the advantage of knowing how to use
the system quickly by using short commands.
In order to ensure that users in both these groups can use the system to their
satisfaction, in the F01/F02 it is possible to select a Standard dialog for inexperienced
users or a Short dialog for experts.
The Standard dialog provides detailed information while operation is in progress, but
the Short dialog dispenses with this information for the sake of rapidity.
Example:
Standard dialog:
SYSTEM: Say the name of a place
USER: Munich - shows up on the display
SYSTEM: Did you mean Munich ?
USER: Yes
Short dialog:
SYSTEM: Place
USER: Munich - shows up on the display
SYSTEM: Did you mean Munich ?
USER: Yes

The dialog setting can be toggled between standard and short by selecting Settings
Language/units .
Language/units
Language Setting
The current voice recognition systems do not offer the customer the option of changing
the input language without expert assistance. The car has to be brought to the workshop,
where BMW Service can change the language setting. The language is changed either
by recoding or by replacing the appropriate control unit.
The new 7 Series BMW enables the customer to change not only the display language
but also the input and output language of the voice activation system by means of iDrive.
The full range consists of eight languages:
" English (UK)
" French
" German
" English (US)
" Italian
" Spanish
" Dutch
" Japanese
All eight languages are saved on the hard disc.
Depending on the national-market specification, however, only three different languages
are selectable with iDrive. The other languages can be activated by coding.
The menu item for changing the language setting is:
Setting - Language/units .

F01 Voice Activation System
No beep after each step in a dialog sequence
Until now, before enunciating a command the
user always had to wait for a confirmation beep
marking the conclusion of a system message.
This does not conform to the natural flow of
speech, and often results in errors because the
user speaks too soon.
In the F01/F02 there is no beep between the
individual steps in a dialog sequence. There are
now only two audio signals: One signal confirms
the start of a dialog sequence and sounds
immediately after the user presses the PTT
PTT button
(push-to-talk) button on the steering wheel.
A second signal sounds to mark the end of Index Explanation
the dialog.
1 PTT
Visual feedback in the instrument panel
In addition to the acoustic feedback issued by
the voice input and activation system, the user
also receives visual confirmation of the result
(e.g. after enunciating the command New num-
ber via the instrument panel. The system s
input prompt e.g. Enter digits appears at the
same time in the instrument panel.
Consequently, the user has improved orientation
and can more easily follow the sequence of
functions and the changes from menu to menu
in the CID.

Combined mode with voice and iDrive inputs
This new function enables the user to operate the system by a combination of spoken
commands and iDrive actions.
Until now, voice input has always aborted as soon as the controller was used to select an
entry. This meant that the user had to press the PTT button again in order to resume
voice input to complete the sequence.
In the F01/F02 the voice-input dialog remains open even if the controller is moved, so the
user can immediately resume voice input to continue interacting with the system. This
makes it much easier, for example, to enter a destination for the navigation system by
selecting a street name from a list.
Extended destination entry in navigation
Voice-assisted destination entry has been extended in the following ways:
" Entry of intersections spoken command
" Entry of Zip codes
Voice control with up to 3000 entries
Until now, the phone book was the only administration function for which voice input
could be used. In the F01/F02 it is now possible to use spoken commands to adminis-
trate the contacts, phone book and the address list. This means that three lists with up to
3000 entries can be operated by voice control.

System Components
The voice input and activation system is implemented in the following control units:
" Telematics Control Unit (TCU)
" Voice input and activation system
CIC
The voice-input commands are transmitted via MOST or the central gateway module
(ZGM) to the receiving control unit.
Voice output consists of recorded audio signals stored in the control unit for the voice
input and activation system. The audio signals are then made available on the MOST
bus in the form of digital signals.
TCU
The TCU used on the F01/F02 is an evolved unit based on the TCU from the E70.

The Voice Activation system supports all the menus viewable on the CID. Voice control
also extends to the second level of the menu tree.
The CIC has eight languages, all saved on the internal hard disc. Three of these
languages are user-selectable by iDrive. The other languages can be activated by coding.
The volume of voice output can be adjusted by means of the multifunction steering
wheel and the IHKA/audio control unit.
The CIC is mounted behind the IHKA/audio control panel in the instrument panel.
