Customising how applications interact with the hosted or on premise VoiceVault biometric verification server is made possible via the VoiceVault web service API.

The API provide capabilities that enable the development of applications that are able to access functionality on the VoiceVault verification engine in a variety of implementation scenarios and architectures.

In its basic form the VoiceVault Web Service permits an application to enrol a person by capturing speech samples and generating a "voiceprint". It then accepts samples of a person's speech (an 'utterance') from an application, together with the claimed identity of that person which could for example, be an account number or PIN.

Using the utterance and the claimed identity, the VoiceVault verification engine will determine a quantitative degree of confidence as to how well the speech matches that of the enrolment-time voiceprint. This information (the 'score') is then returned to the application so that it can make an authentication decision.

VoiceVaultWebLink API Key benefits and features

• Fully-exposes all the functionality of the iometric engine
• Available for hosted or on-premiseengine installations
• Full sample code supplied in Java, VB.NET and C#
• Security via a certificate authority SSL certificate
• Optionally no client-side installation needed

The VoiceVault Web Service provides capabilities that enable the development of platform-independent, machine-to-machine applications that are able to access, over an intranet or the Internet, functionality on the VoiceVault verification engine. The VoiceVault Web Service methods themselves enable an application to send voice and supporting data, and appropriate instructions though to the standard VoiceVault API, and from then on to the voice verification engine.

With the provided web service methods it is possible to develop a range different of types of application including:

• Browser-based
• Interactive voice response (IVR)
• Mobile applications (e.g. iPhone)
• Windows, Linux or Unix services
