Make a call by using a voice tag
If the phone has an application running that is sending or receiving data
using a GPRS connection, you must end the application before voice
dialing.
1. In the standby mode, press and hold the volume down key. A short
tone is heard, and
Speak now
is displayed.
2. Say the voice tag clearly. The phone plays the recognized voice tag,
and dials the phone number of the voice tag after 1.5 seconds.
If you are using a compatible headset with the headset key, press and
hold the headset key to start the voice dialing.
