Referring to fig. 1, a method for adaptively adjusting multimedia volume provided in an embodiment of the present invention is applied to a vehicle-mounted terminal, and includes the following steps:
step S11: speech in the ambient sound in the vehicle is recognized.
The in-vehicle ambient sound includes human voice (including talking, calling or other sounds) generated by the occupant and various other sounds, and may be mixed with multimedia sounds generated when the in-vehicle ambient sound is collected. Specifically, the method of recognizing the speech in the in-vehicle ambient sound is to extract various features of the in-vehicle ambient sound that may exist in the in-vehicle ambient sound, and compare them separately.
In one embodiment, the process of recognizing the speech in the environmental sound in the vehicle is specifically as follows:
extracting the characteristics of the environment sound in the vehicle and the characteristics of the multimedia audio, and comparing;
and recognizing the environment sound in the vehicle based on the comparison result, and comparing the characteristics of the environment sound in the vehicle with the preset voice characteristics.
In the first comparison, the environment sound in the vehicle is collected through a microphone arranged in a carriage, converted into digital information and extracted with the characteristics, and simultaneously the characteristics of the multimedia audio existing in the multimedia are extracted, so that the interference of the multimedia audio mixed in the environment sound in the vehicle is eliminated; in the second comparison, the preset voice characteristics may be a tone database, and the characteristics of the in-vehicle environment sound after the first comparison are compared with the preset voice characteristics, if the matching is successful, the in-vehicle environment sound contains voice.
Step S12: and determining a seat corresponding to the voice and the current driving state.
Specifically, after the voice information is recognized, the generating direction of one or more voice information is further judged so as to determine the current seat where the speaking passenger is located, and meanwhile, the current driving state of the vehicle is obtained from the automobile system, wherein the driving state comprises a driving state and a parking state.
In one embodiment, the process of determining the seat corresponding to the voice specifically includes:
acquiring speech from at least two locations;
and determining the generation seat of the voice according to the difference of the acquisition time of the same voice acquired from the two orientations.
Distributed microphones are arranged and respectively positioned at each position in the carriage of the automobile, the loudspeakers arranged in a distributed mode can be positioned at the front left position, the front right position, the rear left position, the front position or the rear position, and the like, and each loudspeaker can adjust bass, middle pitch, high pitch, loudness, volume and the like, so that each area in the automobile can independently correspond to one loudspeaker. For example, two microphones are arranged at the left position of the front row and the right position of the rear row respectively, when the passenger talks, the time difference exists when the front row microphone and the rear row microphone acquire the same voice information, and the position of the speaking passenger can be judged by combining the time difference, the sound velocity and the relative distance between the two microphones and each seat.
Further, the process of determining the seat corresponding to the voice may further include:
acquiring pressure information applied to a seat;
and determining the generation seat of the voice by combining the acquisition time difference and the pressure information.
Each seat is provided with a pressure detection device, whether a passenger sits on the seat is judged according to the change of the pressure information, for example, the pressure information of the seat is increased by the pressure value of no passenger sitting, the passenger sits on the seat is determined, when the seat where the speaking passenger locates is determined, the seat which meets the time difference range and the pressure information range is judged according to the time difference and the pressure information, and the seat where the speaking passenger locates is judged.
Step S13: and reducing the multimedia volume according to the voice generated on the seat and the current driving state.
After the voice and the corresponding seat are recognized, the multimedia volume reduction operation which does not affect the current driving state is carried out according to the current driving state, namely, the multimedia volume output related to the driving is maintained according to the current driving state.
Specifically, step S13 includes the steps of:
reducing multimedia volume output based on the recognized speech;
and maintaining the driving-related multimedia volume output of the driver position according to the current driving state.
The driving state comprises a driving state and a parking state, and in the driving state, the navigation driving is started or not started, and the navigation state can be a scene that the navigation is carried out by utilizing a vehicle-mounted terminal or the navigation is carried out by utilizing a plug-in device but the navigation is accessed to the vehicle-mounted terminal for broadcasting. Exemplarily, recognizing voice in the vehicle, if the current driving state is a navigation driving state, reducing other multimedia volume outputs except the driving related multimedia volume output of the driver position, maintaining the volume outputs of navigation broadcasting and adas system voice notification, and simultaneously converting the navigation broadcasting mode into a simple broadcasting mode; similarly, the voice in the vehicle is recognized, if the current driving state is the state that the navigation driving is not started, the volume output of the voice notification of the adas system is only maintained, and if the current driving state is the parking state, all multimedia volume output is reduced.
In an embodiment, the step S13 may further include the steps of:
reducing the multimedia volume output of the non-occupant seat;
when the passenger seat generates voice, the multimedia volume of the voice generating seat is reduced.
The method is suitable for the vehicle type with the loudspeaker arranged on each seat, and the multimedia volume output of each seat is specifically adjusted according to the number of passengers and the corresponding sitting condition. Specifically, after the multimedia is started, according to the detection result of the seat pressure information, the seats are divided into passenger seats and non-passenger seats, the volume output of a loudspeaker at the non-passenger seats is reduced or stopped, the loudspeakers corresponding to other passenger seats sound normally, when the voice corresponding to the passenger seats is detected, the multimedia volume output of the loudspeaker at the passenger seats is reduced, the voice is accurately reduced in a subarea mode, a relatively quiet environment is provided for talking or talking passengers, and the normal multimedia volume receiving of other passengers is not influenced.
For example, when the passengers in the driver seat and the passenger seat are confirmed according to the pressure information change on the seats, the in-vehicle machine system automatically adjusts the center of gravity of a sound field in the vehicle, so that the sound volume is concentrated on the front row of the vehicle for output, particularly the sound volume is output from a loudspeaker positioned in the middle of the front row of the vehicle; when the vehicle is in a driving process and voice information generated by communication between a driver and a co-driver is detected, the system automatically reduces all media volume except navigation volume and adas volume of the driver, and the playing mode of the navigation volume is switched to a simple broadcasting mode, or the media output volume of the co-driver is reduced when the co-driver is detected to make a call.
Referring to fig. 2, on the basis of the above steps S11-S13, the method for adaptively adjusting multimedia volume includes the following steps:
step S14: and when the intensity of the voice in the environment sound in the vehicle is lower than the threshold value, the multimedia volume output is recovered.
And after the steps S11-S13 are executed, the multimedia volume output is reduced according to the position of the actual voice and the driving condition, and the multimedia volume output is automatically increased after the conversation or conversation is finished.
