How to customize Bellman's voice system
system is composed of some voice files and a voice format
The files may be any of mp3, wav or ogg. For naming
files, there are two types:
Numerical voices such as zero, one, two, three, ...,
twenty, and so on, have to be named files as e00,
e01, e02, e03, ..., e20 and so on. Here, the
character 'e' is a prefix sign
corresponding to English language. For other
languages, the prefix sign is listed below:
So, any way, to make a new customizing voice style,
you have to select a language listed on Common
option screen to
Non-numerical voice can be named any words or
It is a text file. Its file extension must be ".brf". It
can be saved in any folder on SD card. All external
voice files referenced by the format file must be saved
in the same folder.
How to compose a Voice Format
The first line and all odd lines are voices
sequence lines. The second line and all even lines are condition lines
to be compared to determinate if their previous line, a voices sequence,
may be selected to report time.
M = 0 & [ H < 20 | ( H % 10 ) = 0 ]
!TheTimeIs,( H / 10 * 10 ),( H % 10 )!Oclock
M = 0
A voices sequence line is composed by file
names of voice waves, H, f( H ), M, as well as f( M ) according to a sequence
you want, separated by comma (Space character is not allowed).
Example 1: !TheTimeIs,H,!Oclock
Example 2: !TheTimeIs,H,( M / 10 * 10 ),( M % 10 )
A file name must be leaded "!", e.g. "!ENowTime.wav"
or "!ENowTime". A file extension may be omitted because it will be
matched by program autommatically.
H is represented current time hour numbers.
It is 24 hour format. It will be replaced with a name of voicing number wave file by
program automatically depending on current hour number, e.g.
"e08.wav" for English voice.
M is represented current time minute
numbers. It will be replaced with a name of voicing number wave file
by program automatically depending on current minute number. e.g.
"e50.wav" for English voice.
Here f( H ) and f( M
) are represented formulas to get a number to voice. You have to
replace it with a formula in the line.
Example 1: ( M / 10 * 10 )
Example 2: ( M % 10 )
A formula must be bracketed by "( "
and " )". Note: there is a space character.
Only be H, M and constant number
allowed for operands.
Only be +, -, *, / and %( modulus )
allowed for operators.
All operands and operators are
seperated by a space character between each other.
A voice file name written in a format,
include numerical voice file name produced by program depending on
H, M, f(H) and f(M), is matched with file names firstly in the
folder where the format file saved, then matched with built-in
resources voice names (Please reference
Built-in default format
A condition line is composed by one or
multiple comparison expressions, each other connected with logic
operators "&"( AND ) or "|"( OR ).
Example 1: M = 0 & [ H < 20 | ( H % 10 ) = 0 ]
Example 2: M = 0
Only be "=", "<" and ">" allowed as
comparison expression's operators.
Only be H, M, f( H ),
f( M ) and constant number allowed as comparison
There is only one level "[ " and " ]"
brackets allowed to use to change priority of logical combining
among comparison expressions. Note: there is a space character along
There is a space character between
comparison expression and logic operator.
The program matches conditions one by one
from second line (that is the first condition line) to the last line
until one successful. So, in fact, the last voices sequence line is
unconditioned, that is say the last condition line must be canceled. It
is replaced with "#" to announce the end of lines.
default format files:
Czech voice format
German voice format
Spanish voice format
English voice format
French voice format
Italian voice format
Russian voice format
of customized format:
For English language, how to speaking time in
12-hour format with AM and PM.
In this example, only AM and PM both are
external voice files, all other voices are still
referenced from built-in voices.
The "epoint" is a file name of voice "o'clock".
Second example: It is changed from
to delete "O'clock".
