The invention relates to the formation of packages of the type used typically for pre-cooked meals. The non-ohmic element has a first semiconductor layer which includes at least one diffusion buffering region and a conductive layer adjacent to the first semiconductor layer. The optical beam influencing element is displaceable between a first beam influencing position where a first one of the beam influencing regions is exposed to a bundle of the illumination light, and at least another beam influencing position where another one of the beam influencing regions is exposed to the bundle of the illumination light. The processor is capable of performing the steps of generating text of a word having at least a first syllable and a second syllable, obtaining from the database a first voice recording of the first syllable and a second voice recording of the second syllable, combining the first and second voice recordings, and transmitting the combination over the audio speaker.
