Join the voice commands

The next step is to join the 59 individual voice command files into a single file.

Windows

1.Download and save Viftool to your computer.
2.Extract the files into the folder containing your 59 voice files.
3.Open a command prompt. To do this, click Start, then click Run, and then type CMD and press the Return key.
4.At the command prompt type the name of the drive where you saved your files, for example:
 
C:
 
Then type cd followed by the directory path of the folder in which your voice files are saved.  For example:
 
cd TomTom\Voices
5.Type the following command:
 
viftool join <number> <name> data<number>.vif
 
For example:
 
viftool join 75 John data75.vif
 
Number refers to a unique file number that each navigation voice must have.

Note: Many numbers are already used by the standard and premium TomTom voices. You can check the numbers that are already in use by looking in the voices folder on your device. Number 71 to 99 are recognized as special voices and it is recommended that you use one of the numbers that are in this range.

Name refers to the name of your voice.  It can be between one and eight characters long and must only use ASCII characters.

6.Viftool will then create two files, a .CHK file and a .VIF file.  For the above example you would have these two files:
 
data75.chk
data75.vif

Mac
