Name: SIFT

Text: Speaker ldentification Field Toolkit (SIFT)
Tactical stand-alone i:M speaker identification system
designed f o r offline use by field personnel
- typically field forces, border control and military personnel allowing recording and comparison
against suspects' voices

> I FI - tearure ricn capamllries:
Speaker management
SIFT allows voices of suspects to be stored and
aaditional useful information on them (name, date of
birth, photograph, gender, etc.).
Two easy steps:

I/ Voice recording (or loading)
The voice of the suspect can be directly recorded in
the field (only 7 seconds of net speech are necessary) and
is automatically converted to the optimal system settings.
21 Perform Identification

The system compares the voice sample acquired in
the field (regardless of language and type of speech)
against the database of voices already enrolled and stored
on the laptop.
The identification results consist of a short list of
possible candidates with matching scores (Likelihood
Ratios - LR), ranked from highest to lowest probability.
The results of the identifications can be completed with a
photographfor a second visual identification process.
SlFT has been designed to store up to 1,000 speakers. It
can be installed in a single machine and does not need
centralized server in order to manage its own speaker
database. It allows any operator working in the field to
conduct voice identifications without supervision or a
technical background.

SIFT Functions:

+ Speaker management
+ Voice recordingin the field

9 Speaker ldentification (SID)

SIFT Use cases:

+ Standard operational usage (N:M):

Investigationof a group of suspects in the field (saving
time in sending data to the laboratory)

+ Border access control (%M):

Checking speaker identity by field personnel
SIFT can be seen as a red light I green light scenario:
Green: you go through the control
Red: you do not pass

,Facilitates easy and quick speaker identity
query in the field

+ Speeds up

identification of individuals

SIFT is portable,

friendly, intuitive and easy to use
SlFT uses ACNITlO's proprietary and pioneering voice
biometrics technology (text independent, channel
independent and language independent) based on unique
information extracted from an individual's vocal tract, thus
obtaining a high level of accuracy and reliability.
