Definitions

  • the present invention relates to the synthesis of melodic user-alerting tunes based on Indian classical music in personal and public communication devices. Principally, this invention can be applied to personal phones (landline as well as mobile) and public automated enquiry systems, as ring tones for incoming calls, call waiting, call holding and call transferring. Further, this invention may also find its application in products such as domestic doorbells, alarm clocks etc.
  • the ring tone that is used to signal an incoming telephone call is usually produced by a ringer repeatedly striking one or two bells.
  • the ringing tone is produced by an electronic buzzer, which produces a pitch of a given frequency or a combination of frequencies according to values in a data stream representative of a series of musical tones.
  • U.S. Patent 5,452,354 discloses a ringing tone apparatus, wherein subscriber identification information is used to generate the ringing tone. While this tone generation method is useful for producing different ringing tones for different subscribers, the ringing tones may sound too mechanical and may contain musical notes that are not pleasing when played together. Electronically producing music is well known in the art.
  • U.S. Patent 5,753,843 (Microsoft Corporation [Fay], issued on May 19, 1998) discloses a system and process for composing a musical section in response to a user's interaction with a multimedia presentation. As disclosed in Fay, the system includes a composition engine, a performance engine and an arbitrator.
  • the required computer system has least an INTEL 386SX processor with at least two megabytes of RAM and at least five megabytes of disc storage space.
  • U.S. Patent 6,928,410 discloses a method and apparatus for modification of a speech signal indicative of a stream of speech data having a plurality of syllables.
  • the method comprises the steps of mapping the stream of speech data from the speech signal into a stream of tone data according to a linguistic rule regarding the syllables for providing a tone signal indicative of the stream of tone data forming a string of musical notes responsive to the tone signal for providing a carrier signal indicative of the string of musical notes; While this tone generation method is a random process and creates new ring tones with differences, the ringing tones may contain musical notes that are not pleasing when played together and may sound too dissonant
  • U.S. Patent 7,006,622 discloses a method and apparatus for producing a ringing tone in a communication device, such as a mobile phone, an electronic organizer or a personal digital assistant, to signal an event in the communication device.
  • the method includes the steps of generating a sequence of musical notes in a random fashion within a range of pitch and duration for defining the musical notes, modifying the sequence of musical notes based on a set of modification rules in order to produce a modified sequence, and repeating the modified sequence for forming a motif.
  • This method also chooses the pitch and the duration of the note too randomly to fit them into any particular time signature or measure.
  • a) Monotony In current systems, user-alerting tunes are predefined and set. For example, in the case of personal phones a tune is selected or downloaded (from the service providers' servers) and set as the alerting tune. The tune then is played every time an incoming call is placed. The tune is rendered monotonous. The situation is even worse in public domain systems like automated railway enquiry systems. When the user is put on hold, music is generally played. This tune remains the same over a long period of time. This sort of monotony might lead to an unsatisfactory user-experience.

  • the present invention proposes a method for synthesizing time-sensitive ring tones in communication devices.
  • This invention puts forth a recursive method that generates a new tune associated with various functions of mobile devices, at user-defined time intervals. By making the generation of tunes dynamic and using a permutation of various classical notes, different tunes can be generated, thus ameliorating the problems presented by prior art.
  • This invention finds its application in the area of ring-tones for cellular phones, amongst several other applications.
  • the proposed system is programmed to generate time-variant music, with predefined information about the selection of the time-sensitive Ragas and other dependent parameters, the user does not have to have a deep understanding of classical music and its nuances. Further, the proposed method composes music, while selecting the suitable time-dependent Raga, pace, rhythm and other parameters to ensure that sympathetic user-alerting tunes are generated.

  • the proposed invention is therefore capable of adapting to the needs of the user, as it varies in time and space.
  • the present invention further provides a one-button solution that allows the user to record whether they like or dislike a particular tune. The user, by putting a particular score in the
  • “Liked” or “Disliked” zone gets the internal weighting matrix updated thereby making the future music more tuned to his/her choice. For example, if for a particular time period in a day, the system has been provided with 4 different Ragas, A, B, C and D. Initially, the probability of one of them being played during that time-period is equal, i.e. 0.25. After a while, if the user feels that Raga B is particularly appealing to him from among the four options, he may specify that he likes Raga B, the next time it is played (by means of a simple 'LIKED' or 'DISLIKED' input option in the system). This causes the probabilities of the playing of the 4 Ragas, to be modified slightly such the user preferred

Abstract

La présente invention propose un procédé pour synthétiser des sonneries de téléphone chronosensibles dans des dispositifs de communication. Cette invention propose un procédé récursif qui génère une nouvelle mélodie associée à diverses fonctions de dispositifs mobiles, à des intervalles temporels définis par l'utilisateur. La génération dynamique de mélodies et l'utilisation d'une permutation de diverses notes classiques permettent de générer différentes mélodies, ce qui améliore les problèmes présentés par l'état antérieur de la technique. En outre, l'utilisateur peut enregistrer ses appréciations positives ou négatives pour ainsi surpasser la probabilité qu'une mélodie peu appréciée ne soit jouée trop souvent. Cette invention trouve des applications dans le domaine des sonneries de téléphone pour téléphones cellulaires, parmi plusieurs autres applications.
