Voice activity detection in communication devices for power saving

A method comprising:

• receiving, at a first Bluetooth device, a radio frequency (RF) signal comprising one or more Bluetooth packets from a second Bluetooth device of a communication network;
• determining that the one or more Bluetooth packets comprise audio data;
• determining whether the audio data associated with the one or more Bluetooth packets comprises voice information;
• and
• switching to a power save mode at the first Bluetooth device based, at least in part, on determining that the audio data associated with the one or more Bluetooth packets does not comprise voice information.

A communication device comprising:

• a transceiver unit operable to receive a radio frequency (RF) signal comprising one or more packets from a second communication device of a communication network;
• and
• a power save unit of the transceiver unit, the power save unit operable to:
• determine that the one or more packets comprise audio data;
• determine whether the audio data associated with the one or more packets comprises voice information;
• and
• switch to a power save mode at the communication device based, at least in part, on the power save unit determining that the audio data associated with the one or more packets does not comprise voice information.

One or more machine-readable storage media having instructions stored therein, which when executed by one or more processors causes the one or more processors to perform operations that comprise:

• receiving a radio frequency (RF) signal comprising one or more packets at a first communication device from a second communication device of a communication network;
• determining that the one or more packets comprise audio data;
• determining whether the audio data associated with the one or more packets comprises voice information;
• and
• switching to a power save mode at the first communication device based, at least in part, on determining that the audio data associated with the one or more packets does not comprise voice information.

A communication device comprising:

• means for determining that one or more packets received in a radio frequency (RF) signal from a second communication device comprise audio data;
• means for determining whether the audio data associated with the one or more packets comprises voice information;
• and
• means for switching to a power save mode at the communication device based, at least in part, on determining that the audio data associated with the one or more packets does not comprise voice information.
