摘要:
In a voice communication device in which a control means controls a recording volume adjustment amount for a recording volume adjusting means which adjusts a recording volume of a recording means based on a reproduction volume adjustment amount for a reproduction volume adjusting means which adjusts a reproduction volume of a reproducing means, each adjustment amount is an adjustment absolute amount or an adjustment change amount, and the control means controls the recording volume adjustment amount based on an absolute value or a change amount of the reproduction volume adjustment amount. Also, the control means determines the reproduction volume adjustment amount based on a set reproduction volume.

The collating device includes the Formant estimation section that estimates feature amount data that represents a time-based change in frequencies of first and second Formants from voice data input through the microphone. The difference computing section calculates a difference between some reference feature amount data and the feature amount data as the feature-amount difference data. This feature-amount difference data is stored in a database. The feature-amount difference data corresponding to voice data input upon collation is collated with the feature-amount difference data registered in the database, and the result is output.
摘要:
A semiconductor device superior in heat dissipating performance and permitting reduction of the packaging cost is provided. The semiconductor device comprises a sealing body formed of an insulating resin, a semiconductor chip positioned within the sealing body, the semiconductor chip having a gate electrode and a source electrode on a first main surface thereof and having a back electrode (drain electrode) on a second main surface thereof, a drain electrode plate projecting in a gull wing shape on one end side of the sealing body, an upper surface of a portion of the drain electrode plate which portion is positioned in the sealing body being exposed from the sealing body and a lower surface thereof being connected to the back electrode through an adhesive, a gate electrode plate projecting in a gull wing shape on an opposite end side of the sealing body and being connected to the gate electrode within the sealing body, a source electrode plate projecting in a gull wing shape on the opposite end side of the sealing body and being connected to the source electrode within the sealing body, a depression formed in the surface of the drain electrode plate within the sealing body and filled with the resin which forms the sealing body, and a projecting portion formed on the surface of the drain electrode plate within the sealing body and engaged with the sealing body. The drain electrode plate and the source electrode plate branch into plural branch pieces (leads) serving as gull wing-shaped surface mounting terminals.
