11 Appendix B – Voice Annunciation (iRIS 320V)

The iRIS 320 can be supplied with a voice annunciation feature. In this case it is then allocated the designation, iRIS 320V.

To maintain high quality, natural local sounding audio, including support for almost any language, the iRIS 320V uses special PCM (Pulse Code Modulation) sound files. These are stored in the unit in a dedicated flash memory device that has a total capacity of 2Mb. The files are created from standard 8-bit, mono, 11.025kHz wave files using the Audio Manager function in iLink.

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 320V controller. The partitioning has been designed to allow sufficient space for future bilingual voice support.

Partition	Function	Max File Length
0	Standard Sounds	1 second
1	Sensor Units	2 seconds
2	Sensor Names	3 seconds
3	Site Name / Misc Instructions	5 seconds

Number of Files 44 18 18 12

Partition 0

This partition holds the standard sound files for the digits 0-9, a decimal point and minus. These are used to create the reported measurement values. This partition should be loaded with the appropriate files containing the local words for the following numeric values:

Message 1:	“One”	Message 11:	“Point”
Message 2:	“Two”	Message 12:	“Minus”
Message 3:	“Three”	Message 13:	spare
Message 4:	“Four”	Message 14:	spare
Message 5:	“Five”	Message 15:	spare
Message 6:	“Six”	Message 16:	spare
Message 7:	“Seven”	Message 17:	spare
Message 8:	“Eight”	Message 18:	spare
Message 9:	“Nine”	Message 19:	spare
Message 10:	“Zero”	Message 20:	spare

Partition 1

This partition holds the specific sound files for the units of the nine sensors. For example, if Sensor 3 is measuring air temperature in °C, then the file load ed into Partition 2, Message 3 should contain the local language phrase for “Degrees Celsius”.

Messages 1-9: Sensor Units for Sensors 1-9 respectively.

Partition 2

This partition holds the specific sound files for the measurement names of the nine sensors. For example, if Sensor 3 is measuring air temperature in °C, then t he file loaded into Partition 1, Message 3 should contain the local language name for “Air Temperature”.

Messages 1-9: Sensor Name for Sensors 1-9 respectively.

Partition 3

This partition holds the specific sound files for the site name and specific instructions or information relating to the site.
