The background, development and test databases were allocated evenly in three partitions, with each having 20 speakers.
Moreover, in the current study, a cross validation experiment was also performed by permuting the composition of the background, development and test databases, creating six permutations.
Similarly to the female database, a cross validation experiment was also performed by permuting the composition of the background, development and test databases, creating six permutations.
In particular, the initial 30 speakers (identification numbers: 01 to 30), the next 30 speakers (31 to 60) and the last 30 speakers (61 to 90) were used for the background, development and test databases.
To generate meaningful likelihood ratios from this one offender recording with other suspect recordings, they perform database selection to collect a database of homogenous nature (as described in Section 4.1) suitable for the particular court trial and split the database into background, development and test databases for FVC system development.
In particular, the initial 20 speakers (identification numbers: 01 to 04, 09 to 20, 22, 25, 26, 28), the next 20 speakers (29 to 48) and the last 20 speakers (49 to 68) were used for the background, development and test databases.
FVC results obtained were substantially poorer compared with FVC results from a GMM-UBM system based on the same 60 female speaker database, based on the same database allocation for background, development and test databases as the JFA or i-vector techniques.
The paper reviews the design and construction of a 'hybrid' demonstration building addresses the background development work and testing of the modules and floor cassettes.
Development and testing of the site has taken 3 years.
