1. A system comprising:
a first splitter coupled to a first audio input device, an intercom system and a first input interface to provide a first audio signal received from the first audio input device to each of the intercom system and the first input interface;
a second splitter coupled to a second audio input device, the intercom system and a second input interface to provide a second audio signal received from the second audio input device to each of the intercom system and the second input interface, wherein the intercom system is configured to combine the first audio signal and the second audio signal into a consolidated audio signal;
a first analog-to-digital converter (ADC) coupled to the first input interface to convert the first audio signal into a first input corresponding to the first audio signal;
a second analog-to-digital converter (ADC) coupled to the second input interface to convert the second audio signal into a second input corresponding to the second audio signal;
a shared output interface to be coupled to a communications bus;
a first recognition module coupled to the first ADC and the shared output interface to determine a first textual representation of the first audio signal based on the first input and transmit a first message stream comprising the first textual representation and a first identifier associated with the first audio signal via the shared output interface; and
a second recognition module coupled to the second ADC and the shared output interface to determine a second textual representation of the second audio signal based on the second input and transmit a second message stream comprising the second textual representation and a second identifier associated with the second audio signal via the shared output interface, wherein the second identifier is different from the first identifier.
