Network Integration Capabilities
VoxNauta offers, in addition to conventional network interfaces, an application layer protocol interface based on TCP/IP. This allows for the upgrading of any conventional IVR platform, or any other private network interfacing equipment (e.g. WiFi), to the new and essential features offered by VoiceXML 2.0 and 2.1. At the same time, it exploits optimal integration with speech technologies (ASR and TTS). In this way, any third party equipment can still leverage on its own call control mechanism or access techniques, while upgrading to a fully standards compliant VoiceXML platform.

Integration is straightforward, being based on a simple message-based protocol, and saves time and outlay for companies wishing to exploit a certified VoiceXML browser without having to worry about technology integration. O&M integration is also ensured by the SNMP interface available with VoxNauta.

Multimedia Capabilities Toward IMS
The aim of 3GPP (UMTS scenario), to ensure convergence of cellular and internet technologies, has led to the standardization of the IP Multimedia Subsystem (IMS) architecture, in which multimedia applications are hosted on a SIP application server, described in CCXML and VoiceXML and executed by an MRF (Media Resource Function) component.
Therefore, the essential elements of an MRF are the CCXML interpreter, the VoiceXML interpreter, the speech server for TTS, ASR and DTMF management and the video server for streaming, video/image presentation and co-decoding.
Both CCXML and VoiceXML are media agnostic and therefore suited both for speech and video application development.
Moreover, with the introduction of a few specific, additional VoiceXML elements for video/image presentation and push-to-talk options, VoxNauta is at the forefront for this new emerging and challenging market opportunity.


Multimodal Capabilities over Mobile Data Networks
Loquendo VoxNauta platform can also be used as a network server in multimodal application development for mobile data networks (e.g. GPRS), by exploiting the capabilities of DSR (Distributed Speech Recognition) encoding and Loquendo Embedded TTS.
In this context, multimodal applications are activated by a thin client on the cellular, and described in VoiceXML/CCXML as any other vocal applications.
Uplink payload for vocal commands is dramatically reduced by DSR encoding of the speech front-end parameters, which also ensures reduced channel errors’ sensitivity.
Downlink payload is minimized by exploiting the Loquendo Embedded TTS capabilities, which can be installed on the terminal together with the client software.
In this way, developing multimodal services becomes as easy as writing VoiceXML applications.
