How to turn off the voice.?

What is the source of your TV signal: Cable? Dish Networks? DirectTV? Antenna?
Many times the Cable/Dish Networks/DirectTV controller also has an option for closed captioning. Please verify that a controller is not setup to deliver the CC data.
Also, try setting the TV CC using 'C1' or 'T1' and selecting 'Enter' to accept the change; then come back and set CC to 'Off' again to see if toggling on/off helps.

FIRST U HAV RESTORE UR PHONE AFTER CHGE UR SSETTING IN TUNE OPTION

I had this problem with my previous TV (Syntax by Olevia, an off brand). It only happened to me on certain channels, and for certain shows. What is happening is the TV station is broadcasting the audio in Dolby 5.1 format. For some stupid reason, the TV is playing the background speakers (effects) instead of the speaking parts. You get a little bleed-over of the voices into the back speakers, so voices are there but really quiet. Unfortunately my TV didn't have any surround sound options to fix this.

See if your TV has a surround sound option. Otherwise, you will need to connect the TV sound output to a surround sound system that can properly decode the audio channels.

Go to control panel and check sound and audio devices...under voice tab check the setting also try to look whether front mic option is selcted or rear one.......do reply back

Heh, you have the voice changer on and it as "child"

It's just a (funny) function the phone has in it..

Go to MENU-> Call center -> General call settings -> More -> Voice mode and change the "voice mode" to "Normal"

OR

when you are calling go to options (left button) and there pitch where you can also change the voice.

Hope this helps!

• You should be able to switch demo mode off by pressing the preferences button (the one with four small circles printed on it), then select Route Options, then tap the right arrow button until you get to page 4 which is the Demonstration and Logging screen. Then untick the SmartST shop demonstration box.
  If that doesn’t work you could try doing a factory reset.

went on the "menu" option and formated the disk. I first downloaded the files I needed to my computer. Took off the "lock" option.

Seems like the songs u downloaded and put onto it were messed with. Try deleting them and then re-download them and see if that works

try dialing *780, you should hear beep beep beep confirming that it is turned off. press *78 to reactivate.
