    Abstract: Push to talk (PTT) devices that communicate packet-based voice communications are disclosed. An example PTT device receives voice packets via a packet-based communication network from another PTT device. Voice information in the received voice packets are used to reconstruct the voice communication. The receiving PTT device is able to identify an occurrence of at least one delayed, corrupted or lost voice packet, and then communicate a packet re-transmit request to the other PTT device requesting a replacement voice packet that has a portion of the voice communication that is identical to the voice communication portion of the delayed, corrupted or lost voice packet. The voice communication may then be repaired based on the received replacement voice packet. While the voice communication is being repaired, a comfort tone may be generated so that the listener of the PTT device understands that the voice communication is being repaired.

    Abstract translation: 披露了传送基于分组语音通信的一键通（PTT）设备。 示例PTT设备经由来自另一个PTT设备的基于分组的通信网络接收语音分组。 接收到的语音数据包中的语音信息用于重建语音通信。 接收PTT设备能够识别至少一个延迟，损坏或丢失的语音分组的发生，然后将分组再发送请求传送到另一个PTT设备，请求具有语音通信的一部分的替换语音分组， 与延迟，损坏或丢失的语音分组的语音通信部分相同。 然后可以基于接收到的替换语音分组来修复语音通信。 在正在修复语音通信的同时，可能产生舒适音，使得PTT设备的听众理解语音通信正在被修复。
