Hi,

Prompt format is CCITT u-Law, 8 kHz, 8 bit mono for the WAV files

To convert your prompt for these parameters please use Audacity,Goldwave or any online converter.

managed to get it working using goldwave.

initially i convert the files using online converter that didnt allow me to choose u-Law.

my user find the voice prompt a little too soft.

how can I make it louder  in volume ??

Hi,

 Yes we can increase using audacity software . open the file and increase or decrease the volume .

To increase or decrease the volume, use the slider bar with the +/- to increase/decrease the sound.

if you want to record use gold wave software .go to Tools -speech  converter type the text and save as  speak to file
