Abstract: A portable computer has a voice section and is capable of processing texts and verbal inserts originating from the voice section. The computer comprises a voice conversion unit, a hard disc unit for the storage in memory or the reproduction of texts and of verbal inserts and function keys (FN F9) to command the access to a voice management program (VOICE). An annotation command (ANNOTATE) permits the visual display on a screen and the leaving in the text of a linkage track for a verbal insert datum. The computer comprises a cover, which carries preset keys which are accessible from the outside for the handling of verbal inserts as in a cassette recorder. The computer links the inserts both in a commercial WP program texts and in texts of a resident program NOTE which is specialized for texts with call-ups for the inserts. It further provides a plurality of compression/decompression programs for compressing and decompressing the voice signals in accordance with differing quality/occupancy ratios of the memory.
