Abstract
A system according to an aspect of the present invention switches between the activation/deactivation of the speaker and microphone in speakerphone mode to help ensure the quality of audio communications. The system includes a processor, a microphone, a speaker, and a data relay transceiver. The microphone, speaker, and data relay transceiver are each in communication with the processor. The system further includes a memory in communication with the processor which stores instructions that, when executed by the processor, cause the processor to determine a threshold based on an average amplitude of a signal provided to the speaker by the data relay transceiver; sample the amplitude of the signal; and disable the microphone and enable the speaker if the sampled is greater than the threshold.
