Definitions

  • This invention pertains to recording voice
  • the method for dictating and then listening to voice messages is largely determined by the devices available for dictation.
  • the prior art is replete with recording devices that save information by
  • cassette tape selectively magnetizing a layer of magnetic-oxide material that is bonded to a thin flexible tape, commonly referred to as cassette tape.
  • the user listens to the recorded messages by rewinding the tape to the beginning of a message and playing it.
  • 0 Tape is a medium with deficiencies that until the present invention have been unavoidable, but we have become so accustomed to them that we often forget the drawbacks. We probably owe this willingness to overlook deficiencies to the fact that dictation 5 devices have become indispensable to business.
  • a solid state digital hand held recording device having a single function and multifunctional switch assemblies.
  • a printed circuit board including a microcontroller electrically coupled to said switch assemblies operates to control the processing of sound into electrical signals and store said signals on a digital recording medium.
  • a single, manually operable rocker-pad functioning as the multifunctional switch assembly is centrally mounted upon a pivot support of the hand held recording device. The rocker-pad actuates electrical signals coupled to said microcontroller thereby activating a sequence of actions (a program) stored within the microcontroller in a read-only memory (ROM) device.
  • ROM read-only memory
  • a plurality of programs can be activated by the manually operable rocker-pad to process digitally recorded sound as the user desires.
  • the process of playing back a message without knowing where the message begins in flash memory on the recording medium includes the steps of (i) placing the recording device in the idle mode, and (ii) pressing the play switch to activate a microcontroller program that instructs the microcontroller to find an address pointer in memory that always defines the point in said memory that the recording device is to begin playing. If the user pauses a message that is playing, the address pointer does not move so that play can be resumed from the point of interruption. If the user records a new message, the address pointer points to the beginning of the new message. If the recording device is in idle mode and the user presses the reverse or fast- forward switch, the address pointer points to the beginning of the previous or subsequent message relative to the message that the address pointer was pointing to before a switch was activated.
  • a further disclosure is the method for playing a previously recorded message forward at half-speed, which includes the steps of (i) playing any previously recorded message, and (ii) while the message is playing, pressing the play switch again to toggle between normal speed and half-speed playback.
  • Also disclosed is the method for playing a previously recorded message forward at twice normal speed which includes the steps of (i) playing any previously recorded message, and (ii) while the message is playing, pressing and holding the play switch to enable twice-speed playback.
  • a further disclosure is the method for playing in a forward direction a previously recorded message at up to ten times normal speed, which includes the steps of (i) playing any previously recorded message, and (ii) while the message is playing, pressing and holding the fast-forward switch to enable ten times normal speed forward playback.
  • the last disclosure is the method for playing in a backward direction a previously recorded message at up to ten times normal speed, which includes the steps of (i) playing any previously recorded message, and (ii) while the message is playing, pressing and holding the reverse switch to enable ten times normal speed backward playback.

  • rocker-pad 30 (figure IB) disposed under the rocker-pad 30 are aligned with said electrical contacts 32.
  • an electrical contact corresponding to the rocker-pad extremity 31 makes contact with a corresponding switch terminal 22.

  • a user with a recorder in idle mode immediately begins playing a message at the touch of a switch, regardless of where in a message the user might have stopped while recording or playing.
  • the recording medium of the present invention is digital flash memory.

  • Figure 4 is a flowchart of the steps for playing back any message at two times the normal speed, normal speed being defined as the speed at which the recording was made. In essence, a user plays any previously recorded message and while playing enters the twice normal speed playback mode.
  • Step 1 designated by 310 shows that the preliminary step is to begin the playback of any message, chosen here to be message A.
  • the green LED 60 will be lit.

Abstract

L'invention concerne un appareil enregistreur numérique portable à semi-conducteurs (10) doté d'un ensemble de commutation multifonctions (31). Une carte à circuit imprimé comportant un micro-régisseur relié électriquement aux bornes de commutation commande le traitement du son en signaux électroniques et met en mémoire les signaux sur un support d'enregistrement numérique. L'ensemble de commutation permet d'envoyer des signaux électriques, en couplage avec le micro-régisseur, pour lancer une séquence d'actions (un programme) se trouvant dans une mémoire morte. Il est possible de lancer une pluralité de programmes pour déclencher instantanément la lecture d'un message quelconque ou de tous les messages ou bien encore faire défiler un message à la moitié de la vitesse normale, à deux fois la vitesse normale, à dix fois la vitesse normale vers l'avant et à dix fois la vitesse normale vers l'arrière.
