Voice Elements

Voice Elements is a Microsoft .NET development environment for building automated telephone systems. Voice Elements was released by Inventive Labs Corporation in 2008, based on their original CTI32 toolkit. Software developers who use C#, VB.NET or Delphi use Voice Elements to write telephony-based applications, such as Interactive Voice Response systems, voice dialers, auto attendants, call centers and more.

Voice Elements Software

In addition to the Microsoft .NET Framework, Voice Elements supports the use of speech recognition, text-to-speech,[1] Dialogic TDM hardware and the Inventive Labs HMP Elements SIP Platform. Applications built with Voice Elements are deployed via Voice over IP, via the Inventive Labs cloud hosting service, or by traditional TDM, such as T1, E1 or analog phone lines.[2]

Users of Voice Elements-based solutions interact by using Touch Tone (DTMF) input or with voice commands through speech recognition technology. In addition, developers may program with pre-recorded prompts or use text-to-speech.

Common applications that are built using Voice Elements include:

  • Tele-Integrations
  • Customer Self-Service IVRs
  • Call Centers
  • Phone Systems
  • Ticket Management
  • Two-Factor Authentication
  • Customer Surveys
  • Store Locators
  • Appointment Reminders
  • Voice/SMS Broadcasts
  • Political Polling
  • Power Dialer
  • Reservation Confirmation
  • Collections
  • SMS Marketing
  • Emergency Notifications [3]
  • Order Status
  • Delivery Reminders
  • Flight Information
  • Fundraising
  • Alerts/Notifications

Typically, industries such as Health Care, Retail and Hospitality, and Financial Services use telephony applications to increase customer contact and automate tasks.

Visual Studio developers, by learning the Voice Elements classes, can create almost any voice application. Call logging and sample inbound and outbound applications are a part of the software package.

If deployed via SIP, Voice Elements developers may use the highly tuned Call Progress Analysis that is included in the Inventive Labs SIP Platform. Call Progress Analysis results inform the software if a person or machine answer a call, and are used in outbound dialing campaigns.

WebRTC

Voice Elements launched their WebRTC interface in August 2013 with their Voice Elements Platform 5.[6] It includes a simple API for creating browser-based, feature-rich WebRTC applications. It allows you to focus on the WebRTC functionality you want to provide for your users, without the need to understand the complexities and nuances of WebRTC. WebRTC enables you and your customers to communicate real-time using their computer, tablet, phone or any WebRTC-enabled device.

Voice Elements' session border controller bridges the WebRTC world to the existing SIP infrastructure, enabling your company to make use of WebRTC in a unique way.[7]

This new feature was premiered at the WebRTC Conference & Expo, Atlanta GA, June 25–27, 2013. "The WebRTC marketplace is rapidly developing and evolving, so now is a crucial time for organizations, large and small, to take notice and learn how the latest advancements in communications will impact their business," said Dave Rodriguez, TMC president and event organizer. "We really do have an outstanding group of exhibitors for this event, and together they'll provide a vast and valuable resource for our attendees."[8]

What Can I Build with WebRTC?
Toll Bypass (FREE Calls), Appointment Reminders, Voice Broadcast, E-mail to Fax Systems, Browser-based Phone, Time and Attendance, Full-featured IVRs, Predictive Dialers, Browser-based PBX, Call Center Applications, Auto Attendant, Customer Self Service, Click-to-Call, Two Factor Authentication, Conferencing Systems, Phone Surveys

Premise or Cloud

By building on the Voice Elements platform, you can utilize the cloud service until you are ready to deploy on your own Windows VM behind your firewall. To gain more control and run on your own equipment at your premise, the Voice Elements Platform is designed for seamless porting from Cloud to Premise any time. No programming changes are required.[9]
