  • METHOD FOR TRANSMITTING AND RECEIVING VOICE PACKET AND ELECTRONIC DEVICE IMPLEMENTING THE SAME
    Publication number: 20150063261
    Abstract: A method for enhancing the voice quality of received voice in VoLTE (Voice over Longterm Evolution) includes setting a call with another electronic device, performing a Tx voice enhancement process on first voice data received from a voice input unit, encoding the first voice data, and second voice data received from the voice input unit, following the first voice data, synthesizing the first voice data and the second data, and converting the synthesized voice data into a voice packet and transmitting the voice packet to another electronic device. Other electronic devices for voice packet transmission/reception are also disclosed.
