1 Speech based <strong>Interface</strong><br />
1.1 Component Overview<br />
The overall functional architecture of the Speech based interface has been described in<br />
deliverable D4.1 and D4.2. The Voice interface service consists of the following main<br />
components: Explicit Speech Interaction service, Speaker Recognition <strong>Service</strong> and Implicit<br />
Speech Input <strong>Service</strong>.<br />
The introduced main components and their subcomponents are further treated in this<br />

1.1.1 Voice <strong>Service</strong><br />
1.1.1.1 Speaker Recognition Component<br />
Provider<br />
SingularLogic S.A.<br />
Introduction<br />
Speaker recognition component provides two basic functionalities: enrollment of new users<br />
and recognition of enrolled users.<br />
- Enrollment happens when a new user joins the system – a person speaks and the<br />
application builds a voiceprint model for that person.<br />
- Recognition happens in the future whenever the application wants to ensure the identity of a<br />
speaker – the user speaks and the speech is compared to existing voiceprint models. If the<br />
comparison scores above a predefined threshold, the identity is validated; otherwise the<br />
identity claim is rejected.<br />
Speaker recognition component includes: speaker recognition engine and speaker recognition<br />
server.<br />
Development status<br />
Speaker recognition engine software is available as WIN32 dynamic linked library (DLL).<br />
Speaker recognition server is deployed as an autonomous executable in .NET framework.<br />
Final versions available at INRIA Gforge repository.<br />
