Abstract
Provided is a system, method, and computer program product for improving the quality of voice communications on a mobile handset device by dynamically and adaptively selecting adjusting the latency of a voice call to accommodate an optimal speech enhancement technique in accordance with the current ambient noise level. The system, method and computer program product improves the quality of a voice call transmitted over a wireless link to a communication device dynamically increasing the latency of the voice call when the ambient noise level is above a predetermined threshold in order to use a more robust high-latency voice enhancement technique and by dynamically decreasing the latency of the voice call when the ambient noise level is below a predetermined threshold to use the low-latency voice enhancement techniques. The latency periods are adjusted by adding or deleting voice samples during periods of unvoiced activity.
