- the unit 24 makes it possible to distinguish three states of the acquisition means 4 respectively, solicitation, active and inactive.
- the solicitation state corresponds for example to the activation of a commissioning button of an input unit.
- the active state corresponds to the state in which the acquisition means 4 can actually receive data and the inactive state is the state in which the acquisition means 4 are neither used nor solicited.
- the unit 22 receives the status information of the acquisition means 4 delivered by the unit 24 and directly monitors the signals delivered by the data input units 2A and 2B. Thus, the unit 22 makes it possible to distinguish three different states, namely a data entry monitoring state, a local processing waiting state corresponding to an inactive state of the acquisition means 4 conjugated to a processing in progress. of the received signal and finally, a state of non-reception corresponding to the absence of data entry detection on the input units.
- the state of non-reception may in particular result from an input signal with a weak intensity. Indeed, the unit 22 makes it possible to monitor the signals so as to ensure their quality.
- the means 20 comprise a unit 26 for monitoring the interface means 12 which can switch between states of information reception, information transmission, conversion processing and conversion failure.
- the analysis means 20 are adapted to transmit the status information delivered by the unit 22 and the unit 26 to means 30 for determining a system status information.

- the user decides to make a voice input and activates a button to turn on the microphone 2B.
- the unit 24 detects this action and goes into the request state of a data input, this status information is transmitted by the means 30, which causes the display on the screen 6A of an icon indicating that a data entry is required.
- the acquisition means 4 are active a few moments later only, this active state being detected by the unit 24, the unit 22 then switching to a voice data input monitoring state.
- This state information is transmitted to the means 30 which goes into a processing state of a data entry.
- This state information is passed on to the control means 8 in order to allow, for example, the emission of a sound signal by the loudspeaker 6B and the simultaneous display of a visual index on the screen 6A.
- the audible signal informs the user that the system is ready to receive voice data input.
- the user can then initiate the input of voice data, for example the input of a voice command.
- voice data for example the input of a voice command.
- the unit 22 switches to a non-reception state, this state is detected through the unit 22, means 30 and the control unit. 8, and results in the emission of a new sound signal different from the previous one, reflecting the failure voice input and prompting the user to re-enter their voice data.
- signal quality information delivered by the unit 22 is displayed through the screen 6A.
- a signal strength graph is displayed along with a tolerance threshold, thus allowing the user to adapt his position and his speech to deliver a sufficiently powerful signal and avoid switching to a state of no - reception.
- the acquisition means 4 detect a signal, the unit 24 transmits this state, so that the means 30 delivers a status information of the processing system of the voice command.
- the input voice data is then transmitted by the acquisition means 4 to the interface means 12 which converts them into a format adapted to transmit them to the processing unit 10.
- the interface means 12 convert this signal in text using a speech recognition unit.
- the interface means 12 fails to convert the input data, for example in the case where the speech recognition unit fails to identify a voice command, the unit 26 for monitoring the means 30 flips into a state of failure. This is reflected as previously by the return of a failure state information of the processing of the voice command to the user.
- the voice input data are converted and transmitted to the processing unit 10, they are processed and in the case of a recognized command, cause the execution of an application.
- This execution is reflected, for example, by determining a response to be returned to the user.
- this response is in the form of a multimodal content comprising visual information and audio information.
- the data forming this response are transmitted by the processing unit 10 to the interface means 12, which convert each of the data streams into a suitable format before transmitting them to the control unit 8.
- the unit 26 switches to the information download state, this status information being determined as previously by the means 30 and returned to the user.
- the synchronization units 4OA and 4OB determine the order in which the different data must be transmitted from the processing unit 10 to the control means 8 and the order in which the control means 8 must control the restitution of the information on the data.
- the restitution units 6A and 6B determine the order in which the different data must be transmitted from the processing unit 10 to the control means 8 and the order in which the control means 8 must control the restitution of the information on the data.
- the system can simultaneously manage data download states and rendering states depending on the availability of the elements to be rendered.
- the units 4OA and 40B make it possible to ensure a hierarchy between the transmission of audio and visual data and to synchronize the reproduction of visual and audiophonic data.
- the system returns to a state of waiting, which is detected by the means 30, the status information being returned to the user.
- each unit of the analysis means 20 is directly connected to the control unit 8 and delivers information relating to the operating state of a component of the system such as the means of acquisition or the interface means. This provides the user with detailed information on the status of each of the system components. For example, a system status information is visually reproduced, while a speech signal processing status information is sound reproduced.

- the step E31 is a step of obtaining the operating states coming from different units of the communication system described with reference to FIGS.
- the operating states relate to the operations of the input units (2A, 2B), the acquisition means 4 and the interface means 12. It is possible to receive other operating states according to the units available in the communication system.
- operating states come from the monitoring unit of the input units, the monitoring unit of the acquisition means and the monitoring unit of the interface means.
- examples of operating states input units are a data entry monitoring state, a local processing standby state, and a non-receiving state.
- the operating states relating to the acquisition means are, for example, an active state, an inactive state and a bias state.

- the system state will be in processing state of an entry. The state of the system will only enter the interrogation state of the processing unit when all the acquisition means (4) are again inactive and the interface means (20) are no longer in the reception state. information for any of the entries.
