Abstract

The invention relates to a method for generating an auditory message in an interior of a vehicle, the method comprising: detecting a parameter of an acoustic content by a sensor in the interior of the vehicle; and generating an auditory message dependent on the detected parameter of the acoustic content by a computing unit of the vehicle.

Description

The invention relates to a method for generating an auditory message in an interior of a vehicle. Furthermore, the invention relates to a system for generating an auditory message in an interior of a vehicle comprising at least one means built into the vehicle or carried by the vehicle. Furthermore, the invention relates to a corresponding computer program and a corresponding appropriately configured mobile user device.

Vehicle audio systems have a volume control that allows the volume of an audio output to be adjusted by a driver of the vehicle. Also known from the prior art are systems which, for example, dynamically adjust the volume of the audio output at an increased noise level in an interior of the vehicle. Also well-known in the art are audio systems used in vehicle messages, e.g. in the event of an on-board computer or a navigation system of the vehicle, adjust the volume of the audio output dynamically.

It is therefore an object of the invention to efficiently improve generating an auditory message. In particular, it is an object of the invention to achieve a more efficient perceptibility of an auditory message in a vehicle interior.

This object is achieved by the features of the independent claims. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

According to a first aspect, the invention is characterized by a method for generating an auditory message in an interior of a vehicle, e.g. of a motor vehicle. The method comprises detecting, in particular predicting, a parameter of an acoustic content by one or more sensors, e.g. a camera sensor and / or a microphone sensor, in the interior of a vehicle, and generating, in particular adjusting or varying, the auditory message depending on the detected, in particular predicated parameter of the acoustic content in the interior of the vehicle. The acoustic content may be a voice of at least one occupant of the vehicle and / or an audio signal in the interior of the vehicle. The audio signal can be distributed by a multimedia system, also called infotainment system or head unit, of the vehicle or by a mobile user device.

The said parameter of the acoustic content may be one, e.g. time-ordered, sequence of several parameter values, e.g. in terms of the near past, such as the current time, and / or a near future prediction. For example, a parameter of the acoustic content may also be a measure of the change in the values of a particular parameter value over time and / or in relation to a space-related quantity, e.g. Represent direction or distance. At least one parameter of the acoustic content may be included in the method based on sensor data, a history, e.g. in connection with one or more communications in the vehicle interior or communications involving certain persons and / or considering a probability calculation. Preferably, at least one parameter of the acoustic content, in particular based on an adjustment or billing of a plurality of the parameters from the history, can be predicted.

The auditory message may be in linguistic form, e.g. in the form of a vehicle preset language, information to be output. Further, the auditory message may include non-speech information, e.g. a sound, a sequence of sounds, or melodies. Furthermore, the auditory message may be a combined form having different proportions of linguistic and non-linguistic information. In particular, it is characteristic of the auditory message that the auditory message comprises a content to be interpreted by at least one occupant of the vehicle, for example in relation to a present trip, a state of the vehicle, or a driving context. In particular, the auditory notification is generated within the vehicle depending on information from a vehicle on-board network. By generating the auditory message in response to information from the vehicle on-board network, the auditory message may differ from a multimedia content being broadcast or played by a volume or data stream. For example, the auditory message may be a predetermined audio signal, a combination of audio signals, or a combination of portions of an audio signal indicative of a warning, acknowledgment, vehicle misoperation, and / or information indicative of an automatic generated linguistic communication within the vehicle.

The auditory message may additionally or alternatively be a warning signal and / or a voice signal of a mobile user device connected to the vehicle, eg a smartphone, a tablet, a smart watch, and / or an augmented reality (AR) goggles. This may be an auditory message related to the driving context of the vehicle be. The mobile user device connected to the vehicle can, for example, receive information about an acoustic content of, for example, a microphone of the vehicle via an interface of the vehicle and generate an auditory message or adapt an already generated auditory message. In particular, the auditory message represents information that is at least predominantly relevant to a particular occupant, eg the driver of the vehicle or the occupants at certain seats, eg front seats or rear seats, of the vehicle.

Advantageously, an auditory message can be flexibly generated and / or adapted depending on the acoustic content detected in the interior of a vehicle. The auditory message can thus be generated more efficiently and provided more intelligently. Vehicle occupants get the auditory message depending on the acoustic content of their communication. For example, if the acoustic content represents an important conversation of the vehicle occupants, generating the auditory message may be suppressed and made up for later. An auditory message may be adapted to vary information represented by tones, sequences of tones, or melodies. Alternatively or additionally, in turn, tones, sequences of tones, or melodies can be adapted, which represent a substantially unchanged information. In other words, the same information, e.g. a driver information with other, adapted tones, sequences of tones, or tunes are output. In this case, at least a first criterion of an auditory message with a certain type or a specific content can be adapted, while at least a second criterion, which characterizes the auditory message as an auditory message of the particular kind or with the particular content, is issued or amplified unchanged. For example, one or more frequencies and / or amplitudes in which the tones are output may be adjusted while a tone sequence remains substantially constant. Thus, the auditory message through human perception is still sufficiently recognizable or interpretable.

According to an advantageous embodiment, the acoustic content in the interior of the vehicle may be a voice message of one of the occupants of the vehicle, and / or the parameter of the acoustic content may be determined by detecting a readiness of communication of at least one occupant of the vehicle. By recognizing the willingness to communicate, the generation of the auditory message can already be adapted or varied before a voice message of an occupant. This can be prevented that an auditory message interrupts a communication of a vehicle occupant when the vehicle occupant begins to speak.

According to a further advantageous embodiment, the method may include determining a type and / or a priority of the acoustic content in the interior of the vehicle, and / or determining a type and / or a priority of an auditory message to be generated, and generating the auditory message depending on the determined type and / or the ascertained priority of the acoustic content in the interior of the vehicle and / or the determined type and / or the determined priority of the auditory message to be generated. This can be used to generate an auditory communication depending on a type and a priority. The generation of the auditory message may be controlled dynamically according to its importance relative to the acoustic content.

• - „Wichtig“ aber nicht „Eilig“;
• - „Eilig“ aber nicht „Wichtig“;
• - nicht „Eilig“ und nicht „Wichtig“;

unterschiedlich behandelt werden.Particularly preferred in the method is a comparison of one or more parameters of the acoustic content representing its type and / or a predetermined or determined from the nature of the acoustic content priority measure of the acoustic content, one or more parameters with an auditory message to be issued representing its nature and / or a predetermined or determined from the nature of the auditory message issued priority measure the issued auditory message. Such a comparison of the at least two priority measures can be carried out, for example, according to a prescribed rule, logic, assignment table, etc. In this case, a priority measure determined or processed in the method can identify at least one respective "importance" and / or at least one "urgency". For example, in the method, for example, an audible content with approximately average parameters, auditory messages may have the following priority identifiers:

• - "Important", and "urgent";
• - "important" but not "urgent";
• - "urgent" but not "important";
• - not "urgent" and not "important";

be treated differently.

Depending on the alignment of the read, determined or estimated priority measures, an adaptation of the auditory message to be output can take place. In this case, the time of the output and / or at least one, in particular acoustic parameters in the output of the auditory message can be varied. For example, if only a short time interval between a linguistic Communication is detected or predicated, an auditory message is issued at the appropriate time interval. In this case, at least the time or a time interval of the output of the auditory message is adjusted. Further, the method may also adjust the time at which the auditory message is to be ended and / or the auditory message time interval. In particular, the auditory message may be appropriately placed or scheduled within an available time interval within a communication between the at least two occupants of the vehicle. For example, it may be output between two phrases of a speaker or a speaker's phrase, with a time interval until an expected response of the phrase by another occupant being sufficiently determined, predicted, or estimated. Further, depending on the adjustment of the said parameters, information intended for output as an audible message can alternatively or additionally be output as a visual message, eg image, graphic, text or symbol or a haptic message, eg vibration.

For example, if it is determined from the adjustment of the parameter that the acoustic content is to receive an overall higher priority than the acoustic message, the auditory message can be suppressed or output at a later time and / or with changed parameters. For example, if it is determined from the alignment of the priority measures that a particular auditory message has an overall higher priority measure than a certain auditory content, the auditory message may be associated with a changed parameter, e.g. louder or predominantly from another loudspeaker, and in addition a visual or graphical and / or haptic message are output. In the method, one or more auditory messages can be generated on this basis, wherein the times for their output are selected such that, in terms of the output time interval, they essentially fit between two further acoustic contents or amplitude maxima of two acoustic contents.

According to a further advantageous embodiment, the generation of the auditory message can be suppressed if a communication intention of an occupant of the vehicle is detected by a camera sensor of the vehicle, a voice of an occupant of the vehicle is detected by a microphone sensor, and / or an output of a multimedia device. Audio signal is present. Alternatively, the auditory message may be generated in preferably updated form when using means of the vehicle comprising at least one computing unit, e.g. is determined in a control unit of the vehicle that the communication project of the occupant is no longer present, and / or the voice of the occupant in the interior of the vehicle no longer sounds, and / or at least a pause of a currently reproduced audio signal is present. This can be used to control the generation of the auditory message efficiently and context-dependent.

According to a further advantageous embodiment, the acoustic content may be a voice of an occupant of the vehicle, and generating the auditory message depending on the voice of at least one occupant of the vehicle and / or depending on the voice of an occupant at a particular seat in the interior of the vehicle Vehicle done. This can be used to generate the auditory message personalized to one or more specific persons.

According to a further advantageous embodiment, the acoustic content may be a multimedia content, and / or the acoustic content may be predicted by means of an analysis of an audio data stream prior to a reproduction of the audio data stream. This can be used to control the generation of the auditory message as a function of a preferably predicted acoustic content of an audio data stream. The generation of the auditory message can thus be dependent on characteristics of an audio data stream and thus depending on the currently output and / or future output audio data stream, e.g. a music data stream to be customized in the interior of the vehicle.

According to a further advantageous embodiment, the voice may be a person's voice, in particular a voice of a previously known person or a voice belonging to a group of people in the interior of the vehicle, and generating the auditory message depending on a recognition of the voice of the known person or one Voice belonging to the group of people in the interior of the vehicle done. This can be used to generate the auditory message based on person and / or person group. The generation of the auditory message can thus be controlled individually.

According to a further advantageous embodiment, the detection of the parameter of the acoustic content may include predicting the acoustic content by detecting a communication project of at least one occupant of the vehicle by a camera sensor of the vehicle, and / or recognizing recognizing a lip movement of the at least one occupant and or detect a physical movement of the at least one occupant by means of the camera sensor. This can be used to generate the auditory message based on communication gestures. Generating and outputting an auditory Message simultaneously with a linguistic communication of a vehicle occupant can be efficiently prevented.

According to a further advantageous embodiment, the method may include teaching one or more keywords, word sequences and / or mimic patterns of at least one occupant, e.g. with means of the vehicle, in particular by an arithmetic unit of the vehicle, and recognizing a willingness to communicate and / or a relevance of the detected acoustic content depending on the learned keywords, word sequences and / or mimic pattern of the at least one occupant, and / or adjusting one or several parameters of the acoustic message depending on the learned keywords, word sequences and / or mimic pattern of at least one occupant include. This allows the vehicle to adapt to the environment and in particular to a communication situation of one or more occupants in the interior of the vehicle, so that the vehicle can learn when an auditory message is to be output depending on the communication situation.

According to a further advantageous embodiment, the method may include training a voice and / or a physical impulse of at least one speaking occupant of the vehicle at one or more time intervals, and adapting the acoustic message to the voice of the at least one speaking occupant if the voice of the at least a speaking occupant at one or more later time intervals, eg is recognized by the arithmetic unit, in particular the control unit of the vehicle. This allows the vehicle to adapt to the environment and in particular to a communication situation of one or more occupants in the interior of the vehicle, so that the vehicle can learn when and how an auditory message is to be output.

According to a further advantageous embodiment, the voice of the at least one speaking occupant in the interior of the vehicle can be distinguished from a voice from a multimedia player, in particular an infotainment system of the vehicle and / or a multimedia player coupled to the vehicle. This can efficiently improve the recognition of a person by the vehicle.

In one example of the method, the auditory message may be, e.g. be a driver information, in particular a based on a sensorially detected information to be output from the environment of the vehicle information. Such information may indicate a current or predicted distance and / or risk of collision with one or more objects in the environment of the vehicle. For example, the auditory message may include an audible signal to be output that is generated due to approaching an obstacle in the vicinity of the vehicle. Such a signal may be generated from a parking or shunting system of the vehicle.

In particular, the "acoustic content" is two or more clearly audible acoustic effects in the interior of the vehicle. In the method, a cumulative acoustic content is preferably determined or predicted. In this case, in the method, the individual contents of the acoustic content (at least roughly) can be distinguished from each other and different, e.g. with a predefined, different weighting and / or logical rules, to be considered in the procedure. For example, an adaptation of the auditory message to a sudden sound may deliberately be more pronounced than to a substantially similar background music.

In the method, one or more auditory messages may be generated based on this, wherein the amplitude, frequency parameters, tone sequences, timing parameters, such as, e.g. Parameters of the so-called envelope (so-called "Envelope"), increase parameters and / or decay parameters, a so-called dynamic range to be adjusted. These can be determined in such a way that a sufficient perceptibility of the auditory messages and / or a reduced disturbance of further acoustic content result.

In this case, for example, sounds, sound sequences of a vehicle system can be adapted so that they are sufficiently perceptible even with a significantly increased current or predicted acoustic content and / or the auditory message yet includes features that are used to assign the auditory message to the particular system of the vehicle or to the particular type of content of the auditory message or information contained therein.

The adaptation of the at least one auditory message can be carried out according to one or more predetermined criteria, for example the user settings.
At least one criterion for adapting at least one parameter of the auditory message preferably represents sufficient audibility and / or perceptibility and / or audible intelligibility. Such perceptibility or audibility or intelligibility can be achieved, for example, by using a psychoacoustic model of a human acoustic perception, in particular in Reference to a specific occupant, identified and taken into account in the procedure.

Another criterion may be at least one vehicle setting or user setting, e.g. a seat or a user profile of an occupant can be assigned. This can represent, for example, the extent to which an auditory message, in particular an auditory message of a certain type and / or priority, should be audible. Certain perception characteristics of at least one particular person, e.g. Parameter representing an audiogram of a particular occupant, be taken into account.

Particularly preferably, in the method, a control of one or more parameters of the auditory message can be performed, wherein a target value of the control is selected depending on a given audibility and / or acoustic perceptibility of an auditory message and / or an acoustic content, in particular continuously adapted.

The generation of an auditory message may be performed in the method such that control signals for controlling the audio system or the onboard computer or the system of the vehicle, e.g. the multimedia system of the vehicle on the basis of which the auditory message is generated. In the method, the generation of the auditory message also includes an analogous adaptation of an already generated or, based on the already present, cached information, to the auditory message to be output. In this case, the method can be applied to the generation of information to be output with the auditory message, to the generation of an underlying data record and / or to the output of the auditory message by a vehicle system. In other words, generating the auditory message involves adjusting an auditory message to be generated.

According to a further aspect, the invention is characterized by a system for generating an auditory message in an interior of a vehicle. The system comprises a sensor which is designed to detect a parameter of an acoustic content in the interior of the vehicle, and a means of the vehicle, comprising at least one computing unit installed or mounted in the vehicle, in particular a control unit of the vehicle, which is designed for this purpose to generate an auditory message depending on the detected parameter of the acoustic content. Furthermore, the arithmetic unit, in particular the control unit of the vehicle, can be designed to carry out the method described above.

According to a further aspect, the invention is characterized by a computer program, in particular a computer program product comprising the computer program, wherein the computer program is designed, when executed on a computer unit, an essential part of the method according to the invention or an advantageous embodiment of the method according to one or more further features of the procedure. In particular, the computer program is a computer program which, for example, can run as an app or application on a device installed or to be carried in the vehicle, comprising at least one arithmetic unit.

The computer program or computer program product in this case comprises an executable program code, which executes in an embodiment by a device comprising a computing unit, at least part of the method according to an aspect described herein or an advantageous embodiment of the method described herein. The computer program product can be designed as an update of a previous computer program, which includes, for example as part of a functional extension, for example in the context of a so-called "remote software update" the parts of the computer program or the corresponding program code for a device of the vehicle.

Further features of the invention will become apparent from the claims, the figures and the description of the figures.

Hereinafter, a preferred embodiment of the invention will be described with reference to the accompanying drawings. This results in further details, preferred embodiments and further developments of the invention. In detail, show schematically

• 1 an exemplary method for generating an auditory message in an interior of a vehicle, and
• 2 an exemplary system for generating an auditory message in an interior of a vehicle.

In detail shows 1 a procedure 100 for generating an auditory message in the interior of a vehicle. The procedure 100 can one Determine parameters of an acoustic content by a sensor, for example by one or more microphone sensors or by one or more camera sensors in an interior 102 , The acoustic content in the interior of the vehicle may be, for example, a voice message or a voice message from an occupant of the vehicle. A parameter of the acoustic content may be indicative of a beginning or an end of the voice message, a progression of a volume, and / or a pitch. Additionally or alternatively, the method 100 Predict a parameter of an acoustic content and / or a communication-related action or a communication project of an occupant of the vehicle. Depending on the determined or the predicted parameter of the acoustic content and / or the predicated communication-related action, an auditory message for output in the interior of the vehicle can be generated or adapted 104 ,

When a sensor of the vehicle detects that, for example, a passenger of the vehicle is just beginning to speak or intends to speak by a gesture, facial expression, or other communication-related action, generating an auditory message of the vehicle to a driver of the vehicle may be delayed adapted to the communication situation. The adjustment of the auditory message can be done for a given time interval. After a lapse of the predetermined time interval, a new adjustment of the auditory message can take place. For example, the auditory message regarding a volume of one or more speakers of an audio system of the vehicle can be adjusted.

The acoustic content as well as the auditory message can be classified according to their type and / or their priority. The classification of the acoustic content and the auditory message can be done according to a predetermined scheme. Preferably, the acoustic content and the auditory message are classified according to the same scheme, so that comparability in terms of importance and / or urgency can be made. Depending on the type and / or priority determined, the importance and urgency of the auditory message relative to the auditory content may be determined and the generation of the auditory message adjusted accordingly.

For example, if it is determined that the acoustic content is a voice message of an occupant, an indoor noise, a multimedia content in the interior, or a sound of a carried user equipment, e.g. is a mobile ringtone, the generation of the auditory message may be adjusted accordingly. For example, the auditory message may be paused, shortened, include less detailed information, spoken faster, and / or split into at least two or more parts.

If the auditory message is an output of a navigation system of the vehicle, the priority of the auditory message may be compared to a priority of the audible content. If the priority of the acoustic content is higher than the priority of the auditory message, the auditory message of the navigation system can be suppressed. If the type of auditory message is a playback of a multimedia content and the type of acoustic content is a dispute between vehicle occupants, the playback of the multimedia content may be paused or stopped. If the auditory message is an urgent audio message, i. an audio message with a high priority, e.g. when an audio message for the acquisition of an autonomous driving vehicle by the driver, there is no adjustment of the auditory message. The urgent audio message is generated and output without change.

The generating of the auditory message may additionally or alternatively be adjusted depending on the voice of an occupant and / or depending on a seat of a speaking occupant. The voice may be a person's voice belonging to a particular person or group of persons. By means of one or more microphone sensors in the interior of the vehicle, a direction of a voice and thus a seat of the speaking occupant can be determined. Depending on the determined direction, the generation of the auditory message can be adapted. For example, the driver's voice of the vehicle may be generating and outputting auditory messages, e.g. Multimedia contents, affect one or more occupants in the rear of the vehicle when the driver's voice is detected and the driver's acoustic content is directed to the occupants of the vehicle in the rear.

The voice of a speaker in the interior of the vehicle can be distinguished from a voice from a multimedia player. Preferably, the voice of a speaker in the interior of the vehicle can be distinguished from the voice from a multimedia system by matching the signals of a microphone sensor of the vehicle and a signal of the multimedia system of the vehicle. For example, the voice of a speaker in the interior of the vehicle of a voice from a multimedia player can be distinguished by determining whether the voice of a speaker is contained in the vehicle only in the microphone system of the vehicle or is recognizable, or if the voice in one evaluated signal of a multimedia system can be detected.

The voice of a particular person can be learned by the vehicle. Upon recognition of the learned voice, a predetermined generation and / or adaptation of the auditory message to the voice of the recognized person can take place. The teaching of the voice of a particular person or a particular group of people can be done in the vehicle, outside the vehicle, and / or by means of a mobile user device. Particularly preferably, a different adaptation of the auditory message can be carried out for at least two voices of two different persons. A group of people may include members of a family. Voices of a group of people can be children's voices, male voices, or female voices. The voice of a certain person can be linked to a professional position of the person. For example, the acoustic content can be prioritized depending on the occupational position.

In addition to the voice, certain key words, word sequences and / or mimic patterns of at least one occupant can be taught in and the auditory message can be generated as a function of the learned characteristics. If a physical sensation, e.g. a certain lip movement pattern is detected in a person who has always spoken softly and / or indistinctly in the vehicle so far, the auditory message can be adapted greatly to match the speech frequency and / or the speech of the recognized person. If a physical sensation, e.g. a certain lip movement pattern is detected in a person who has always spoken loud and / or clear in the vehicle, the auditory message matching the voice frequency and / or the speech of the recognized person can not or only slightly adapted.

If the acoustic content is a multimedia content, the acoustic content may be predicted by analysis of an audio data stream of the multimedia content. For example, an amplitude characteristic of the audio data stream can be predetermined. The auditory message is only generated and output if the amplitude profile of the audio data stream corresponds, for example, to a predetermined pattern of the amplitude profile.

Furthermore, the acoustic content can be predicted or predicted by means of a recognition of a communication project of at least one occupant of the vehicle. The recognition of the communication project can be done for example by means of the recognition of one or more learned lip movements and / or one or more learned physical movements of the person through an interior camera. One or more physical impulses that are known, for example, from an analysis of body language and / or an emotion evaluation and that precede speech, can also be recognized as communication projects. The auditory message can thus be adjusted depending on physical impulses such as a smile and speech, a frightened face and loud talking or shouting. For example, the generation of the auditory message when recognizing a scared face and / or recognizing a hassle or screaming can be switched off, paused, interrupted or adjusted more strongly than with an average degree of communication readiness and / or voice recognition. Preferably, the auditory message may also be prefixed, e.g. be adjusted before or just after the beginning of speaking. This has the advantage that the person who is about to say something, is very anticipated.

In detail shows 2 an exemplary system 200 for generating an auditory message in an interior of a vehicle. The system can have one or more microphone sensors 202 and one or more camera sensors 204 include. The microphone and / or camera sensors 202 . 204 may detect a parameter of an acoustic content in the interior of the vehicle 102 , The sensors 202 and 204 are with a in this example means of the vehicle representative of the computing unit of the vehicle control unit 206 connected via a communication network of the vehicle. The means of the vehicle may generally comprise at least one arithmetic unit and / or sensor, which is set up for operation in a vehicle, and in particular connected to the vehicle, for example to the on-board network of the vehicle for exchanging the data for carrying out the method.

The control unit 206 may receive the parameter of the acoustic content and generate an auditory message depending on the detected parameter of the acoustic content 104 , The auditory message may, for example, be via one or more audio output devices 208 be issued. Furthermore, a mobile user device 210 with the arithmetic unit, in particular the control unit 206 be coupled, wherein the mobile user terminal can serve as a sensor for detecting a parameter of the acoustic content and / or as an audio output device for said auditory message. Furthermore, the arithmetic unit 206 that in conjunction with 1 perform the described method.

In this example, the auditory message relates to acoustically output tones or portions of speech messages that are not limited to mere perception (listening, such as music) but interpreting the appropriate message, at least understanding and / or distinguishing and / or categorizing by at least one occupant , for example, determined by the driver.

For example, auditory messages may include auditory, in particular linguistic information that depends on the driving context of the vehicle (eg traffic signs, traffic jams, other road users) and / or depending on the condition of the driver (fatigue detection, distraction) and / or actions of the driver (references to possible consequences of an action) are generated. For example, the auditory message includes information, e.g. a text portion which is acoustically output in a preset language in a vehicle computer installed or carried on board. Advantageously, by the method and system described above, the output of auditory messages as a function of one or more parameters of an acoustic content in the vehicle interior can take place in a fundamentally improved manner. In this case, the described features of the method, in particular to achieve predetermined optimization criteria in any manner can be combined.

For example, depending on the determination, a high priority measure of a current or predicted acoustic content in the interior of the vehicle, e.g. as "important" and / or "urgent" or "urgent", lead to a much greater adjustment of auditory reporting than to auditory content with a medium or lower priority level. For example, upon detecting a temporal overlap between an acoustic content of certain types and a particular auditory message, the auditory message may be output at an earlier or later time and / or in a shortened form and / or with a changed acoustic parameter.

For example, an adaptation of an auditory message, in particular speech, predominantly or more strongly takes place on the acoustic content in the form of person voices, wherein the person voices can comprise both the (live) spoken contents in the interior and / or voices from a multimedia program and / or telecommunication contents. Thereby no or substantially less adaptation to other sources of noise, e.g. the barking of a dog or horns of other road users or background noise, e.g. Wind noise or specific noise scenes done. This is particularly advantageous because a linguistic message is much more disturbed in terms of their comprehensibility by persons' voices than by further noises.

Alternatively or additionally, an audio signal corresponding to the auditory message can be adapted, wherein the signal energy of at least part of the auditory message is distributed to one or more frequency ranges which have a smaller, in particular the smallest possible overlap or correlation with the frequency ranges of the human voice. in particular to the voice of a particular occupant (the "speaker"). In this case, the perceptibility and / or comprehensibility of the linguistic communication between the occupants of the vehicle and / or the auditory message can be increased, or a mutual interference, in particular a masking (known, for example, from psychoacoustics) can be reduced.

Individual occupants of the vehicle, e.g. Driver, co-driver and rear seat occupants can receive individual, auditory reports, which depend on the voice, the behavior and / or the conversation situation. By using a camera sensor, intentional actions can be detected and taken into account in the generation of auditory messages. The flow of information from the vehicle to the driver can thus be controlled dynamically and intelligently without receiving any annoying or superfluous information. The inmates get exactly the information that is important in the current situation. Thus, the information flow in autonomous vehicles can be controlled more efficiently. For example, the driver can only receive the safety-related auditory messages. All disturbing, non-situatively appropriate, auditory messages can be delayed, suppressed, and / or adapted situationally. For example, an auditory message about a low wiper water level can be suppressed until a gas station is approached and this auditory message receives a high importance for the driver of the vehicle.
