< Comparisons with commercial conventional systems and validations >
Validation results:
(Table 2-3)
As indicated in the table, in comparison with commercial conventional systems the sound pickup level differentials
are notable when there is noise insertion. In the keyboard noise zone, for example, YVC-1000 provided a sound
pickup level of -55.3 dB with respect to -40.8 dB for the commercial conventional systems, thus it suppresses the
noise levels by 14.5 dB more than conventional systems do. In regard to the commercial conventional systems
responding and focusing on the noise orientations, with the YVC-1000 noises and voices are distinguished via HVAD,
and the performance differentials are that the noise orientations are not focused on.
Data measuring method:
In the system configurations in Figure 2-6, the accuracy of detecting a person's voice location was verified. The
performance differentials were compared between the YVC-1000 and commercial conventional systems as to
whether the voices and noises were alternately reproduced, and whether the noises and voices were misidentified.
* The above validation results were obtained using YVC-1000 firmware Ver.1.05.
