14 -
(1). i
defines the group number (from 0 to 255).
(2). N
defines the number of global repeats (from 1 to 16).
(3). m1, m2, m3
and
m4
define the number of local repeats (from 1 to 7).
(4). A, B, C,
and
D
are files containing ADPCM converted voice data.
(5). _flv
is the section control setting, for which the parameters f, l and v are as follows:
f: Sampling Frequency define (default value: f=2)
f
3
2
1
0
Frequency
8 KHz
6 KHz
4.8 KHz
4 KHz
I: LED status define (default value: l=0)
l
1
0
LED status
On
Off
v: Fading Effect define (default value: v=7)
The max. value of the voice is v=7, that is the full scale of the sound. The min. value is v=0, that is
0.1 times of the full scale of the sound. The volume value from large to small is 7> 6> 5> 4> 3> 2>
1> 0.
Note 1: If the section control setting is not defined, the default values are used. For example, in the
speech equation H4+A+T4, if the A sound is played, the default values are used. These values are:
6K Hz sampling frequency (f=2), LED off (l=0), and maximum volume output (v=7).
Note 2: If the section control setting is defined, both the f and l digits must be defined together. The v
digit is optional.
For example:
1. H4+A_2+T4: This is a wrong speech equation since only one digit (f) of section control is defined.
2. H4+A_21+T4: This is a correct speech equation with section control. The sampling frequency is 6K
Hz (f=2), the LED is ON (l=1), and the volume is maximum value (v=7, the default value).
3. H4+A_210+T4: This is a complete speech equation with section control. The sampling frequency is
6K Hz (f=2), the LED is ON (l=1), and the volume is minimum value (v=0).
(6). [1FFFF]
is a period of silence of length 1FFFF (around 5.46 seconds) under the 6K Hz sampling
frequency condition. The maximum silence length in one "[ ]" is [FFFFF], that is 1M bits, around
43.69 seconds under the 6K Hz sampling frequency condition.
The silence can't be placed between
voices and H4/T4 that will generate a little noise. It is necessary to place it on one line as
above example that will gain a good silence.
