TH040 Trigger Voice Combination Example
Voice File |
Description |
Voice File A |
Hello ( 1.5”) |
Voice File B |
Good Morning (3”) |
Voice File C |
John (1”) |
Voice File D |
Tom (1”) |
Voice File E |
Mary (1.5”) |
|
|
Group1 = Step1 + Step 2
Group 2 = Step3 + Step 4 + Step 5
Group 3 = Step 6 + Step 7
Group1 = Hello John
Group 2= Hello Tom Good Morning
Group 3 = Good Morning Mary
Step1 = Voice File A
Step 2 = Voice File C
Step 3 = Voice File A
Step 4 = Voice File D
Step 5 = Voice File B
Step 6 = Voice File B
Step 7 = Voice File E
Total use 3 Group , 7 Steps
Voice duration= Hello + Good Morning + John + Tom + Mary
= 1.5” + 3” + 1” + 1” + 1.5”
= 8”
Total duration = 8” ( 20”-8” = 32” space are free , can add more Voice File )
