## Abstract

The general field of the invention is that of systems for segregating audio messages in a cockpit of a first aircraft. Said system comprises: means for receiving and recording audio messages; a database of keywords for the audio messages; means for recognizing of keywords in the audio messages; means for separating the audio messages as a function of said keywords; means for ranking the messages according to an order of priority; means for processing the audio messages according to said order of priority; means for transmitting the messages processed according to said order of priority; means for listening to the audio messages.

## Claims

### Claim 1

System for segregating audio messages in a cockpit of a first aircraft, said system comprising means for receiving and recording said audio messages, a database of keywords for said audio messages, and means for listening to said audio messages,
wherein the system comprises:
a first computer having the functions of recognizing keywords in said audio messages and separating said audio messages as a function of said keywords,
a second computer having the functions of ranking said messages according to an order of priority and processing said audio messages according to said order of priority, and;
means for transmitting said processed messages to the listening means according to said order of priority, the order of the priorities of the audio messages being a function of the distance or the attitude or the trajectory of second aircraft close to the first aircraft, said second aircraft being identified by the call signs of their audio messages.

### Claim 2 (depends on 1)

System for segregating audio messages according to claim 1, wherein the keywords are aircraft call signs.

### Claim 3 (depends on 1)

System for segregating audio messages according to claim 1, wherein the system comprises means for graphically representing and means for displaying audio messages.

### Claim 4 (depends on 1)

System for segregating audio messages according to claim 1, wherein the processing of an audio message consists in an adaptation of its sound level.

### Claim 5 (depends on 1)

System for segregating audio messages according to claim 1, wherein the processing of an audio message consists in a spatialization of the sound of said audio message.

### Claim 6 (depends on 1)

System for segregating audio messages according to claim 1, wherein the processing of an audio message consists in a modification of the voice reading said audio message.

### Claim 7 (depends on 1)

System for segregating audio messages according to claim 1, wherein the first priority is assigned to the audio messages whose call sign is that of the first aircraft.
