A dual compression voice recordation non-repudiation system provides a voice recognition system that compresses voice samples for two purposes: voice recognition and human communication. It is determined that physical storage is not allocated for the target logical address range. dimensionally stable two-component moulding parts. The degranulation of goblet cells that results in airway mucus production is thereby inhibited. Module initialization is then performed. Thus, the connector is soldered on a circuit board via solder balls on the contacts and the protrusions, thereby preventing the connector from inclining downwardly during in reflow process because of the connecting force between the connector and the board increased.
