Post your VXML application development project on Upwork, the world’s largest online workplace, and hire expert IVR developers and software engineers with VoiceXML experience to create industry-standard interactive voice response applications. They can develop voice exchange platforms, IVR controllers to run through your SIP VOIP server, or Mobile SIP dialers, as well as voice and DTMF apps. These developers can even complete phone chat-line IVR systems with voice mail controllers, or an API- or email-controlled VOIP-based auto dialer.

Voice XML is the W3C standard XML format for creating interactive voice response (IVR) applications with features like audio playback functionality, speech synthesis and recognition, and dialog management. On Upwork, companies hire professional VXML developers to manage IVR development or to create custom VoiceXML API integration and speech recognition engines integrated with other communication software (like FreeSWITCH or Asterisk).

    United Kingdom - Last active: 07/11/2012 - Tests: 21 - Portfolio: 4

    EXPERIENCE: --- I have spent the past two decades between the UK and Germany capturing technical and business requirements and composing the related documentation as a Project Manager, Technical Consultant, Voice User Interface Designer, QA Tester, and nowadays Director of and Principal Consultant at my own UI design, testing and optimisation company, DialogCONNECTION Ltd., which specialises in voice recognition applications and language technologies. I have already provided my services to clients such as: Apple, Raytheon BBN Technologies, and the Gerson Lehrman Group in the US; Barclays, CapGemini, Littlewoods, and the National Health Service (NHS) in the UK; Vodafone, Siemens, Sony, Grundig and Loewe in Germany; Swisscom in Switzerland; and Omilia in Greece. In addition, I have been working on technical, scientific, and business communication (written and spoken) for the past 25 years. With several degrees in languages, Linguistics, and IT [BA in English & American Literature & Linguistics, MSc in Machine Translation, PhD in Automatic Text Summarisation, Post-Doc in Dialogue Processing for Automatic Speech Recognition], I have gained considerable experience conceptualising, authoring, editing and publishing peer-reviewed articles for international publications, as well as technical reports for international business clients. LOOKING FOR ROLES: --- I am looking mainly for roles conceptualising, designing, documenting, testing (functionality and usability), and tuning / optimising speech recognition / voice recognition applications for voice self-service and Call Centres / customer hotlines. --- Equally attractive to me would be Functionality Testing roles, as I have had more than a decade of experience in functionality testing, user acceptance testing, usability testing, load testing, live testing, reporting and debugging. --- In addition, any opportunities to put my rigorous, technology-conscious and yet creative and intuitive English, German and Greek language skills into use would also be welcome. IT Project Management, Technical Pre-Sales, and Technical writing roles are of particular interest to me, as I am an expert in translating high-level business, marketing, technical, and user requirements into concrete business process flows, technical process flows, example use cases, dialogue scripts, and test scenarios. This is why I have always been the perfect bridge between Sales & Marketing teams and IT development & programming teams.
