14 Appendix B
– Voice Annunciation (iRIS 350FXV)
The iRIS 350FX can be supplied with a voice annunciation feature. In this case it is then allocated the
designation,
iRIS 350FXV
. Typically the voice annunciation feature is used to play back the current values of
all enabled sensors when the unit is called up from a telephone.
To maintain high quality, natural sounding audio, including support for almost any language, the iRIS 350FXV
uses standard PCM (Pulse Code Modulation) sound files. These are stored in the unit in a dedicated flash
memory device. The files are standard 8-bit, mono, 11.025kHz wave files and loaded into the iRIS 3x0V using
the Audio Manager function in iLink 2012.
All iRIS 350FXV units are supplied initially with a default set of sound files pre-loaded and these can be
used/modified/replaced as necessary by following the directions in the later part of this section.
To optimise the speed of operation against the available memory, the audio file storage has been divided
into four “partitions”, each able to hold a fixed number of files that can be easily indexed by the iRIS 350FXV
controller. The partitioning has been designed to allow sufficient space for future bilingual voice support.
Currently, only the first half of each partition is used. The second language option will use the second block
of messages in each partition. E.g. Partition 0, Messages 1-22 are for language 1, Messages 23-44 will be for
language 2.
