Product

Voice Communication Package (VCP) is a universal software package of digital signal processing technologies for voice applications enabling high quality, full duplex, noise free communication from various environments. Users of mobile phones, hands-free car kits, Bluetooth headsets, industrial intercoms and other types of voice terminals will all benefit from VCP quality. VCP enabled devices can be used in different scenarios and modes:

• Vehicle-mounted applications in which a hands-free terminal is mounted inside a car (e.g. hands-free car kit); cars of different types are supported with either car built-in or dedicated speaker(s) used.
• Hand-held applications in which a hands-free terminal is held at the arm's length and the internal loudspeaker is used (e.g. mobile speakerphone);
• Desktop applications in which a hands-free terminal is laying on a desktop surface and the internal loudspeaker is used (e.g. office speakerphone);
• Stationary applications where a hands-free terminal is mounted in a stationary device with its own loudspeaker(s) (e.g. portable speakerphone);
• Hand-held applications in which a terminal is held in hand near speaker's ear and mouth (e.g. mobile phone or handset);
• Headset applications, in which a terminal is placed on speaker's ear (e.g. Bluetooth headsets)

VCP includes a number of signal processing components. Basic VCP version includes components required by virtually all voice communication devices. Add-on components provide the user with additional benefits and can be enabled or disabled depending on the required functionality and available DSP resources.
