Abstract
A method for allowing at least one passenger, wearing a personal listening device broadcasting an audio signal, to hear an oral message uttered by an authorized person in a transport vehicle, the method including detecting, recording and encoding said oral message as a voice signal, configuring a “payload signal to noise” ratio in the perceived audio signal, in which the payload signal consists of the oral message and in which the noise consists of the audio signal and stray noise, at a value greater than a predetermined threshold, and broadcasting the voice signal on a wireless communication network, to a mobile terminal connected to the personal listening device or directly to the personal listening device in order to broadcast it to the at least one passenger.

A method for allowing at least one passenger to hear an oral message uttered by an authorized person in a vehicle, said at least one passenger having a personal listening means having an audio speaker, said method comprising the following steps:
- detecting, by a microphone in the vehicle, the oral message uttered by the authorized person, the oral message intended to be made audible to said at least one passenger,
- recording, by a processor in the vehicle, the oral message,
- encoding, by the processor in the vehicle, said recorded oral message as a voice signal, and
- broadcasting said voice signal on a wireless communication network, i) to a mobile terminal connected to the personal listening means or ii) directly to the personal listening means, such that the audio speaker of said personal listening means outputs said voice signal to said at least one passenger.

- a microphone in the vehicle for detecting an oral message uttered by the authorized person, the oral message intended to be made audible to said at least one passenger, said microphone being automatic or activatable;
- and
- a processor configured to:
- record said oral message,
- encode said captured oral message as a voice signal, and
- broadcast said voice signal on a wireless communication network, to a mobile terminal connected to the personal listening means or directly to the personal listening, such that said audio
- speaker of said personal listening means outputs said voice signal to said at least one passenger.
