Apparatus and method for de-jitter buffer delay adjustment

A method comprising:

• determining, at a device, an arrival delay value based on previously received audio packets;
• identifying a receive time of a first audio packet of a talk spurt;
• determining an offset value of the first audio packet based on the receive time and the arrival delay value;
• adjusting a target delay value associated with a de-jitter buffer of the device in response to determining that a difference between a first delay value of a first particular subset of the previously received audio packets and a second delay value of a second particular subset of the previously received audio packets satisfies a convergence threshold, the target delay value adjusted based on the offset value;
• outputting the first audio packet at a first playout time, the first playout time based on the adjusted target delay value;
• and
• outputting a particular audio packet of the talk spurt at a second playout time, the second playout time based on the first playout time and a playout rate.

A computer-readable storage device storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• determining an arrival delay value based on previously received audio packets;
• identifying a receive time of a first audio packet of a talk spurt;
• determining an offset value of the first audio packet based on the receive time and the arrival delay value;
• adjusting a target delay value associated with a de-jitter buffer, the target delay value adjusted in response to determining that a difference between a first delay value of a first particular subset of the previously received audio packets and a second delay value of a second particular subset of the previously received audio packets satisfies a convergence threshold, the target delay value adjusted based on the offset value;
• outputting the first audio packet at a first playout time, the first playout time based on the adjusted target delay value;
• and
• outputting a particular audio packet of the talk spurt at a second playout time, the second playout time based on the first playout time and a playout rate.
