The disclosure relates to an audio system in a motor vehicle.
Car users can get bored during driving, and they may sing alone or with family. While riding in a vehicle, many passengers sing songs, even if there is no music due to only navigation or other non-music related applications playing in the car infotainment unit.
The present invention may provide a personal experience for a driver or passenger who is singing in a vehicle. In response to a user singing a song, the car infotainment unit automatically plays the background music for the song to accompany the user's singing. The car infotainment unit may retrieve and play music in the form of actual karaoke songs which are available over internet radio. The car infotainment electronic unit may use voice recognition to detect the lyrics that the user is singing, and then may find the song based on the recognized lyrics. The words sung by the user and recognized by the infotainment system may be used to search for a piece of Karaoke music in internet radio applications.
In one embodiment, the invention comprises a motor vehicle including a loudspeaker, a voice recognition module, and a microphone producing a microphone signal based upon words uttered by a human passenger within a passenger compartment of the motor vehicle. An electronic processor is communicatively coupled to the microphone, the loudspeaker, and the voice recognition module. The electronic processor receives the microphone signal and communicates with the voice recognition module to thereby ascertain the words uttered by the human passenger. The electronic processor retrieves Karaoke music corresponding to the ascertained words uttered by the human passenger, and plays the Karaoke music on the loudspeaker.
In another embodiment, the invention comprises a method of providing music within a motor vehicle, including using a microphone to produce a microphone signal based upon words uttered by a human passenger within a passenger compartment of the motor vehicle. A voice recognition module is used to ascertain the words uttered by the human passenger. Karaoke music corresponding to the ascertained words uttered by the human passenger is retrieved. The Karaoke music is played on a loudspeaker associated with the passenger compartment.
In yet another embodiment, the invention comprises a method of providing music within a motor vehicle, including using a microphone to produce a microphone signal based upon utterances by a human passenger within a passenger compartment of the motor vehicle. A voice recognition module is used to determine a tonal pattern of the utterances by the human passenger. Music is created having a melody corresponding to the determined tonal pattern of the utterances by the human passenger. The music is played on a loudspeaker associated with the passenger compartment.
An advantage of the present invention is that it may add music to match the singing of a user. Thus, the invention can provide a personalized user experience and create a cheerful environment for the passengers in the car.
A better understanding of the present invention will be had upon reference to the following description in conjunction with the accompanying drawings.
During use, microphone 14 may pick up the audible singing of a passenger 26 within vehicle 12. Microphone 14 may then transmit a microphone signal 28, based on the passenger's singing, to processor 22. Processor 22 may communicate with voice recognition module 20 in order to ascertain the user's words or lyrics in microphone signal 28. Processor 22 may then perform a search for Karaoke music via the Internet 30, using the user's words or lyrics as a search term. Having received the Karaoke music via the Internet 30, processor 22 may then audibly play the Karaoke music on speaker 18.
In one embodiment, during the searching and retrieving of the Karaoke music, processor 22 continues to use microphone 14 and voice recognition module 20 to keep up with the lyrics that the user is currently singing. Upon receiving the Karaoke music, processor 22 may begin playing the Karaoke music at a point within the music that corresponds with the point within the lyrics at which the user is currently singing. Thus, the user does not have to start singing the song from the beginning of the song when the Karaoke music starts to play.
In another embodiment, the Karaoke music is stored in memory 24, and processor 22 searches for and retrieves the Karaoke music from memory 24 instead of from the Internet 30. In yet another embodiment, the Karaoke music is initially retrieved from the Internet 30, but is stored in memory 24 upon being received by processor 22. Thus, the next time it is detected that the user is singing the same lyrics, processor 22 may more quickly and reliably retrieve the Karaoke music from memory 24 instead of from the Internet 30.
The invention has been described as retrieving music from the Internet, or from in-vehicle storage. In another embodiment, however, the music being played is music created by the head unit of the vehicle's infotainment system itself. The infotainment system may use voice recognition to detect the audio pattern uttered by the user, including changes in the tone of the user's voice. Thereby, the infotainment system may ascertain a melody of the song that the user is singing. The audio pattern recognition can then be used by the system to produce audible tones and a melody to accompany the user's singing.
Although the voice recognition module has been described herein as being disposed in the vehicle, in another embodiment the voice recognition module is disposed remotely from the vehicle, and may be internet-based. The processor may wirelessly communicate with the voice recognition module.
Next, in step 204, a voice recognition module is used to define the song being sung by the human passenger. For example, voice recognition module 20 may ascertain the lyrics or words uttered by the human passenger while singing the song, or voice recognition module 20 may determine a tonal pattern of the singing by the human passenger.
In a next step 206, music corresponding to the song being sung by the human passenger is obtained. For example, Karaoke music corresponding to the words or lyrics sung by the human passenger may be retrieved from the Internet 30 or memory 24. Alternatively, music having a melody corresponding to the determined tonal pattern of the human passenger's singing may be created by processor 22.
In a final step 208, the music is played on a loudspeaker associated with the passenger compartment. For example, the music may be audibly played on loudspeaker 18 within a passenger compartment of vehicle 12.
The foregoing description may refer to “motor vehicle”, “automobile”, “automotive”, or similar expressions. It is to be understood that these terms are not intended to limit the invention to any particular type of transportation vehicle. Rather, the invention may be applied to any type of transportation vehicle whether traveling by air, water, or ground, such as airplanes, boats, etc.
The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom for modifications can be made by those skilled in the art upon reading this disclosure and may be made without departing from the spirit of the invention.
This application claims benefit of U.S. Provisional Application No. 62/354,643 filed on Jun. 24, 2016, which the disclosure of which is hereby incorporated by reference in its entirety for all purposes.
