Land Rover Discovery: Operation - Incontrol Touch Audio Systems

The voice control system provides the driver with the option of voice control for a range of supported functions. The following systems can be controlled by voice control:

• Bluetooth Telephone system
• Navigation system
• Radio, satellite radio and digital radio (if fitted)
• USB and auxiliary input connections.

The voice control system uses a 'visual prompter' system known as 'Say What You See' (SWYS). The SWYS visual prompter shown in the TS guides the user through the flow, showing examples of what they can say next, and also confirmation of where they are in the conversation flow.

NOTE:

Telephone voice commands are only accessible when a Bluetooth device is paired to the vehicle.

The system is operated by the voice control switch on the left steering wheel switchpack. Voice commands are detected by the dedicated microphone in the overhead console. When giving a voice command audible feedback will be heard through the vehicle's audio speakers.

Efficient operation of voice control is reliant on the user understanding some of the following basic operating conditions:

• Face forwards, sitting in a normal driving position
• After pressing the voice button, always wait for the end of the audible tone before speaking
• Speak naturally, as if you were talking to a passenger or on the phone without pausing between words
• When the system asks for more information, always wait for the end of the tone before responding
• Always say numbers clearly but at a natural pace
• Excessive noise, for example while driving with windows open, may cause voice command mis-recognition. If it is too noisy to use the phone, it is likely that voice commands will not be recognized.

Most accents are understood without difficulty, but if the system does not recognize the command it will allow two more attempts to say the command.

All feature items listed that can be activated by voice control, can also be activated by touching the relevant command list item on the TS. A list of the available features can be displayed by saying the voice command; "More Commands". Alternatively, saying "All Commands" or selecting 'All Commands' via the TS, will enable visual and audible instructions to be given in a default sequential order, starting with navigation Commands and then followed by other available features. The voice control system will work with the user to display the feature lists individually. Say (or select) "Navigation Commands" or "Phone Commands", then only the relevant commands for that feature will be read out and displayed.

Starting a Voice Session

To start a voice session the driver operates the voice control switch on the left steering wheel switchpack briefly. An audible tone can be heard, followed by the presentation of the 'Say What You See' (SWYS) visual command list in the TS indicating some commonly used available commands. A voice symbol indicates that the system is listening. Always wait for the listening tone to finish playing before using the command. To end a session press and hold the voice control switch until a double beep is heard.

When the voice control switch is pressed on the left steering wheel switchpack, a signal is received by the AHU via the clockspring assembly on a Local Interconnect Network (LIN) bus. A voltage is sent on a single wire from the switchpack, through a resistive ladder and converted to a LIN bus signal. The whole process is then initiated via the APIX2 connection between the AHU and the TS; for example the TS starts the voice session and carries out the resulting action requested by the user, but the AHU maintains the dialogue with the user. The SWYS visual prompter is calculated and presented in the TS when requested to do so by the AHU.

The accompanying voice feedback is sent to the Audio amplifier Module (AAM) for broadcast over the speakers from the AHU. If a recognized user instruction is received via the microphone, this is then processed and sent to the TS to perform the required action.

Navigation Destination Entry by Voice

Destination entry uses phonetic transcriptions of the navigation data (stored as part of the map data) to offer the user the ability to enter an address or postcode into the Navigation system by voice. The user simply follows the visual and audible instructions given by the voice system and enters their desired address in a step-by-step manner or one shot destination entry (for example; House No, then Street, then Town).

At each address entry stage, the user's voice command is matched against the phonetic map data and a list of likely recognition candidates is presented in a "pick list" for the user to select from. If the chosen address has more than one location associated with it, the voice system will work with the user to determine the exact address they wish to navigate to.

Dialling from the G2P Phonebook

Provided the phonebook has been downloaded via Bluetooth, the voice system is able to perform a grapheme-to-phoneme (G2P) transcription of each of the names stored in the phonebook. This is then used by the voice system to allow the user to dial a contact by saying the name stored in the phonebook, there is no need to store a voicetag first.

The user's voice command is matched against the phonebook entries and a list of likely recognition candidates is presented in a "picklist" for the user to select from. If the chosen contact has more than one number associated with it, the voice system will work with the user to determine the exact number they wish to dial.

The contact name must be spoken as displayed in the phonebook in the TS.

The system will attempt to recognise names based on the currently selected voice language. Foreign contacts may not be recognised correctly and depending on the characters used, may not be recognised at all.
