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).
