My phone says no voice tags found ...what does this mean ?

Touchscreen phones simplify the wireless world, especially when combined with voice activation. Although making calls using voice commands was an option before touchscreens became available, the method used to set up this feature is different than it is for non-touchscreen units. It can take time to master the set of procedures that will get the feature working.
Step 1
Create a voice tag. Touch "Contacts" on the today screen. This opens the list of contacts on your phone. From here, do one of three things: you can hold your finger on the desired contact and then tap the "Add Voice Tag," you can select the desired contact, tap on "Menu" and then "Add Voice Tag," or you can tap the desired contact to open their personal screen and then hit "Menu" followed by "Add Voice Tag."
Step 2
Record the voice tag on your phone. Touch the phone number to which you wish to add a voice tag then touch the "Record" button. Record your voice tag for that contact. An icon will be displayed to the right of the number when the voice tag is complete. You can listen to your voice tag by touching the "Play" button on the screen or you can delete it to record a new one.
Step 3
Make a voice tag for a program. Tap the "Start" button on the phone. Go to "Settings" and then the "Personal" tab followed by "Voice Speed Dial." Choose the program for the voice tag and record the voice tag in the same manner as you did for the contact. To open the program with the voice tag, tap "Start," "Programs" and then "Voice Speed Dial."
Step 4
Launch a program or make a call. Make a call by tapping "Start" followed by "Programs" and then "Voice Speed Dial." You will hear a beep. Say the voice tag you recorded for the person you wish to call. You can open a program via the same procedure (by speaking the voice tag created for the program).
Step 5
Check the voice tags you created. Tap on "Start," "Settings," "Personal" tab and then "Voice Speed Dial." A voice tag tab appears and displays a list of your voice tags.

Does not depend on the phone, is the phone company that provides voice message service.

Delete some SMS and you will have more free memory to add a tag to a contact that you must save on the telephone and not on the SIM

You should be able to add a voice tag while editing the contact. You may also be able to simply activate voice dialing and press the voice dial button and say the name of the person and it will automatically dial for you. Try doing that.

You do not have to record voice tags for your contacts. Go to Tools, click on Voice Command then Settings and finally Train. Follow the prompts and once complete, your phone will them be able to recognize your commands. when you hit the call button on your bluetooth headset, the phone will say "Say a command". at that point you can tell it to call any contact in your list or tell the phone to call a number (i.e. call 601 555 0123). The phone will ask for conformation and then make the call. The phone will also respond to request to check missed calls, check voice mail and tell you the time and date. Hope this helps.

choose the contact you want then seek for add voice tag.

receive contacts is the same as voice tags. Use voice tag menu to receive contacts from your phone.

Voice tag is what enables you to call by speaking. So say you have a contact named Bob on your phone. You press the button and the phone beeps and you say "Bob" to call him. If you say it clearly, the phone will display Bob (and possibly any other contact that is close in name to Bob). If you don't do anything within a few seconds, it will start dialing Bob. That is the voice tag. My guess is your phone does not support voice tag or you dont have any voice tags assigned to your contacts. You will have to call from the handset, not the headset.
