Voice modification for wearable device

A system comprising:

• a wearable device, the wearable device comprising a digital signal processor, a processor operatively connected to the digital signal processor, a microphone operatively connected to the digital signal processor, and a Bluetooth transceiver operatively connected to the processor;
• a device having a Bluetooth transceiver adapted for connecting with the Bluetooth transceiver of the wearable device;
• an audio modification software application executing on a processor remote from the wearable device;
• wherein the digital signal processor is configured to receive an audio signal and encode the audio signal using a codec to provide an encoded audio stream;
• wherein the wearable device is configured to route the encoded audio stream from the digital signal processor over a Bluetooth parallel transport channel that operates concurrently with and is distinct from a Bluetooth hands free Profile (HFP) channel from the Bluetooth transceiver of the wearable device to the device;
• wherein the audio modification software application executing on the processor is configured to modify the encoded audio stream at the processor to provide an encoded modified audio stream;
• wherein the device is configured to communicate the encoded modified audio stream over the Bluetooth parallel transport channel back to the wearable device;
• and
• wherein the wearable device is configured to communicate the encoded modified audio stream from the wearable device over the Bluetooth hands free profile (HFP) channel to the device.
