| Voice Activity Compression (VAC) |
A method of conserving transmission capacity by not transmitting pauses in speech. |
|
| VAD (Voice Activity Detection) |
Voice Activity Detection. When enabled on voice port or a dial peer, silence is not transmitted over the network, only audible speech. When VAD is enabled, the sound qualify is slightly degraded, but the connection monopolizes much less bandwidth. |
|
| Value Creating Gap |
This represents a performance gap where your call center is doing better than your Peer Group. |
|
| Value Destroying Gap |
This represents a performance gap where your call center is doing worse than your Peer Group. |
|
| Virtual Call Center |
The concept of having network and agent resources that are located at multiple physical sites perform as if all resources were located at a single site. |
|
| VoFR (Voice over Frame Relay) |
Voice over Frame Relay. Enables a router to carry voice traffic (for example, telephone calls and faxes) over a Frame Relay network. When sending voice traffic over Frame Relay, the voice traffic is segmented and encapsulated for transit across the Frame Relay network using FRF.12 encapsulation. |
|
| Voice Authentication |
A technology used to verify the identity of a person accessing a system by comparing spoken passwords with prerecorded computerized voice patterns. |
|
| Voice Processing |
The technology that allows computers to speak, store human voices, and react to human speech. |
|
| Voice Recognition |
A telephone system using speech recognition to activate equipment that dials telephone numbers automatically. May be speaker-dependent or independent. |
|
| Voiceband |
A transmission service with a bandwidth considered suitable for transmission of audio signals. Generally 300, HZ or 500 Hz to 3,400 Hz. |
|
| VoIP |
Voice over IP. Enables users to transfer voice communications over a data network using the Internet Protocol (IP). In VoIP, the DSP segments the voice signal into frames, which are then coupled in groups of two and stored in voice packets. These voice packets are transported using IP in compliance with ITU-T specifications H.323. |
|
| VRU |
Voice Response Unit. Also referred to as IVR (Interactive Voice Response Unit). A device which automates retrieval and processing of information by phone using touch tone signaling or voice recognition to access information residing on a computer to give a response. The response may be given by a recorded human voice or a synthesized (computerized) voice. |
|
| VXML |
Voice-Enhanced Extensible Markup Language. Existing Web sites predominantly employ HTML. VSML is a proposed standard that will bring the power of Web development and content delivery to self-service voice applications. That is, allowing for Automatic Speech Recognition or keypad input to access Web pages that are interpreted and spoken back to the caller with recorded prompts and/or Text To Speech technology while using an industry standard Programming language (VXML) to accomplish this. |
