Table 4: Synthesized voice message table
Messages are formed by combining a message from each of the columns.
For instance, to build the phrase "Floor One", choose "Floor" from the first column, "Silence" from
the second and "One" from the third. Hence the values of
Sint 1
and
Sint 2
will be chosen as follows:
Sint1
=
“
Floor
”
+
“
Silence
”
= 0x08 + 0x00 = 0x08,
We always force bit 7 to be 1, and so finally,
Sint1
= 0x88.
Similarly for Sint 2:
Sint 2
=
“
One
”
= 0x52, (again we set the most significant bit to 1) and it becomes 0xD2.
