Abstract: A computing system includes first and second client computing devices accessing a communications network to establish a communications session. The first client computing device operates an audio analysis agent to determine network latency within the communications session based on communications with an audio analysis agent in the second client computing device. In response to the network latency exceeding a latency threshold, audio input from a user of the first client computing device is analyzed to determine a speaking status of the user. The audio analysis agent generates an indicator command message for the second client computing device based on the determined speaking status of the user. The second client computing device displays an indicator based on the indicator command message indicating when a user of the second client computing device can speak to avoid speech confliction with the user of said first client computing device.
