2.1 The Speech Dialogue System
2.1.1 Introduction
The speech dialogue system enables you to operate some of the mobile phone’s functions by
voice input. It recognizes commands and sequences of numbers independently of the person
speaking. The commands and sequences of numbers can be spoken without a break between the
individual words. You can also save telephone numbers using a name chosen by you (voice tag).
Later, a telephone call can be initiated by using this voice tag. If the voice control system fails to
operate properly or fails to recognize your voice, it provides you with acoustic messages and asks
you to re-input the command you want. The speech dialogue system also confirms important
commands and, when appropriate, asks for further information.
Before you dial a telephone number, the following preconditions must exist:
The mobile telephone must be ready for operation and a Bluetooth connection must exist.
The mobile telephone must be registered in a GSM network.
If no phone is connected you will receive the audio messages: “No phone connected” and “You
can say Pair or Select device”.
For most phones the PIN-code must be entered before (This applies to phones which don’t support
Bluetooth reconnection without entered PIN).
2.1.2 Activating the speech dialogue system
You can activate Speech dialogue system by pressing the “Push-To-Talk” button. An active
phone call should not be taking place. If you do have an active call and press the “Push-To-Talk”
button, this starts the “Barge In” process (see below for details). In this case not all speech
commands are available.
2.1.3 Ending the dialogue
You can stop the speech dialogue at any time via the “Stop” button.
It is also possible in other ways:
• Via the voice command “Cancel”.
• After second time-out: if nothing has been said for a certain period of time.
• After the third unrecognized command (noticeable through the voice prompt “Cancel”).
2.1.4 Operation

With the aid of the voice control system, you can operate the mobile telephone very comfortably
using the voice input function. Simply activate the speech dialogue system and say the desired
command. Once the command has been input, you will be led through the dialogue with the
corresponding questions and messages in order to reach the action you require.
The infotainment system reacts to your commands simultaneously with voice messages and
display changes.
If you keep silence then the system gives the message “No speech detected” and ends the speech
recognition session.
If system cannot recognize the given command then it asks you “Pardon?”. After a second
unrecognized command the system recites all the available commands. And after a third attempt
the system ends the current speech recognition session.
2.1.5 Main menu commands
After the speech dialogue system has been activated, you will hear a short sound, which is a signal
to inform you that the voice control system is waiting for your input.
The following commands are available:
• "Dial"
• "Call"
• "Redial"
• "Save"
• "Delete"
• "Directory"
• "Pair"
• "Select Device"
• "Voice feedback"
• "Help"
• "Cancel"
When no phone is connected the system supports only a subset of commands: “Pair”, “Select
Device”, “Voice Feedback”, “Help”, “Cancel”.
2.1.6 Barge in
If you are in an active call then you can initiate a second call via the speech dialogue system. This
is done by pushing the “Push-To-Talk” button. The list of commands available after you activate
the “Barge In” process is:
• Send – permit to send DTMF via digits input.
• Send nametag - permit to send DTMF via a saved nametag.
• Call – you can call via nametag.
• Dial – you can dial a number you provide.
• Redial – you can redial last dialled number.
• Help – described below.
• Cancel – end the speech recognition session.
Example of DTMF sending:

User: Send
Voice Output: Please, say the number to send.
User: 123456789
User: Send.
The interrupted call will be continued after deactivation of the “Barge In”.
2.1.7 “Dial”
Say the telephone number in a normal voice. Recognition is most successful when you pause for
at least half a second after every three to five numbers. You can input single digits and block of
digits. To input the block of digits you should say the number without pause. After each pause the
system plays back the previously entered digit or block of digits.
To verify the input you could use the “Verify” command. This command will play back the
previously entered digits. The infotainment system then repeats the recognized numbers.
The maximum length of a dialled number is 25 digits. Otherwise the system plays back the
message “Too many digits entered”.
If you enter a wrong number then GSM network will inform you about that.
After you said “Dial” you can then input the following commands:
• “Dial” - the number is confirmed.
• “Delete” – it will delete the last entered digit or block of digits.
• “Plus” - a plus is inserted (used for calls abroad).
• “Verify” – plays back the inputs.
• “Digits” – digits (1, 2… 9, 0).
• “Star” – a star-symbol is inserted.
• “Pound” – a pound-symbol is inserted.
• “Help” – described below.
• “Cancel” – the speech recognition session is ended.
Example of a Dial-dialogue:
User: Dial.
Voice output: Please say the number to dial.
User: 12345
User: Dial
Voice output: The number is being dailled
Korean digits can not be entered by blocks, but only digit by digit.
2.1.8 “Call”
Using this command, you can input a telephone number which has been saved in the phone book
under a name (voice tag) that can be used to create a connection. If you have no voice tags saved
you will receive the audio command “Directory is empty”. You could create some voice names
using the command “Save”.
The commands that you can use here are:
• “Yes” – according to the context of question it will give the appropriate result
• “No” – according to the context of question it will give the appropriate result
• "Help" - The dialogue is ended and all commands available in this context are listed.

•
"Cancel” – end the speech recognition session.
Example of a Call-dialogue ()
User: Call.
Voice Output: Please say the nametag to call.
User: .
Voice output: “Do you want to call ?”
User: No.
Voice output: “Please say the nametag to call?”
User: 
Voice output: “Do you want to call ?”
User: Yes.
Voice output: Calling
You have three attempts to enter a correct voice name. After a third unsuccessful attempt the
system ends the speech dialogue.
2.1.9 “Redial”
Using the “Redial” command, you can redial the last dailled number. If there is no previously dailled
number then the system sends you the message: “No number to redial.”
Example of using Redial (last dailled number exists):
User: Redial.
Voice Output: Redialling…
2.1.10 “Save”
Using the “Save” command you can save the contacts. Each contact contains the number and the
nametag. Saved nametag is related to the phone number and is valid for every connected phone.
The maximum number of contacts that can be saved like this is 50.
Available commands:
• “Save” – accept digit inputs.
• “Verify” – playback the digit inputs.
• “Help” – described below.
• “Cancel” – end the speech recognition session.
If you try to save more than 50 contacts then you receive the message “Directory is full”.
If you save a nametag you must repeat it twice and your utterance must be the same. Otherwise
you will receive the message “The nametags are too different”.
You cannot save two contacts with the same nametag. In this case you receive the message “The
nametag sounds too similar to ”.
The maximum number of digits in the number is 25. Otherwise the system plays back the message
“Too many digits entered”
Example of saving of a voice tag:
User: Save.
Voice Output: Please say the number to save.
User: 1234567.

Korean digits can not be entered by blocks, but only digit by digit.
2.1.11 Delete
Using the "Delete" command from the main menu, you can delete any voice tag. If the directory
does not contain any nametag then the system will play the audio “Directory is empty” and end the
speech recognition session.
The commands that you can use here:
• "Help" - The dialogue is ended and all commands available in this context are listed.
• "Cancel” – end the speech recognition session.
• “Yes” – according to the context of question it will give the appropriate result
• “No” – according to the context of question it will give the appropriate result

Voice Output (if all nametags displayed): End of directory.
Voice Output: Ending session.
2.1.13 “Pair”
Using the “Pair” command you can add or delete a device to or from the device list. This allows you
to later select the device from the list to start a Bluetooth session (for details see the next chapter).
The maximum number of devices in the list is 5. If you add a sixth device it replaces the least
recently used one from the list.
Four commands are available after you said “Pair” (if device list is not blank):
• Add device - using the “Add” command, you can add the new device into the device list for
future pairing.
• Delete device - Using the “Delete” command, you can delete the device from the device
list.
• Help – described below.
• Cancel – end the speech recognition session.
Example of adding of new device:
User: Pair.
Voice Output: Do you want to add or delete a device?
User: Add.
Voice Output: Using the pair function in the external device, enter  to pair.
Voice Output: Do you want to pair the device?
User: Yes
Voice Output: The device is paired as number .
Voice Output: Ending session.
Example of deleting of device:
User: Pair
Voice Output: Do you want to add or delete a device?
User: Delete.
Voice Output: Please, say a device number to delete.
User: .
Voice Output: Do you want to delete device number ?
User: Yes.
Voice Output: Device number  is deleted.
Voice Output: Ending session.
If the device list is empty then the audio prompt “Do you want to add or delete a device?” is
omitted. Instead, the system immediately asks you to add a new device.
2.1.14 “Select device”
Using the “Select device” command, you can select a device for a Bluetooth session.
Example of device selecting:
User: Select device.
Voice Output: Please say a device number to select.

Voice Output: Do you want to select the device number ?
User: Yes.
Voice Output: One moment. The system is searching for the selected device.
Voice Output: Device number  is selected
Voice Output: Ending session.
2.1.15 “Voice Feedback”
Each word that you say using the speech dialogue system has an appropriate audio feedback
which contains some set of words. You can switch on and off these words using the “Voice
Feedback” command. Depending on the current state of the Voice Feedback toggle (On or Off) the
system will switch it to the inverse position (if it is On then it will be Off and vice-versa).
The system also uses different beeps for different events. There are 4 kinds of beeps: beep for
positive acknowledge tone (used if Voice Feedback is off), beep for negative acknowledge tone
(used if Voice Feedback is off), beep for ending a session and beep for listening.
Additionally there is another way to skip voice messages the system gives you: just press the
button “Move-On/Skip”. Then the system will stop playing the current voice dialogue and play back
the listening beep.
After you switch on or off “Voice Feedback” system provides ending of speech recognition system.
So you would need to activate the speech dialogue system again to verify the result of your
changes.
2.1.16 “Help”
Using the "Help" command all possible commands are said.
2.1.17 "Cancel"
This command can be used to finish a speech recognition session.
2.1.18 PIN code
This feature works only with the few mobiles which can reestablish a Bluetooth connection without
entering the PIN before. You can input single digits and blocks of digits.
The following commands are available:
• "Accept" – the PIN code is confirmed.
• "Delete" – the last entered digit is deleted.
• “Dial” – dial emergency number.
• “Pound” – a pound-symbol is inserted.
• “Verify” – plays back all entered digits.
• “Help” – described above.
• “Cancel” – ends the speech recognition session.
Example of a dialogue whereby a PIN code is entered:
Voice output: Please say the PIN code then Accept.
User: 1234, accept.

If you enter a wrong PIN you receive the audio message: “Wrong PIN Code” and the system asks
for the PIN once more. You have only 3 attempts. After a third unsuccessful attempt you will
receive the audio message “Phone not ready”. Then you must enter the PUK code.
PUK cannot be entered via the speech dialogue system – it is only possible via the keypad.
The maximum length for the PIN is 8 digits. Otherwise the system plays back the message “Too
many digits entered”.
