The Rubidium RSV100 provides a total solution to manufacturers and designers wishing to use biometric speaker identification to implement multi-user Voice Password in their product. The RSV100 combines cutting edge digital speech processing technology with state-of-the-art optimized silicon design to provide a single chip self-contained solution.

An RSV100 chip is a multi-user Voice Password processor intended to identify a group of users by their voice and the spoken password of their choice. Any foreign voice is rejected, even when speaking one of the right passwords. A registered user will also be rejected if they speak a wrong password. The RSV100, therefore, provides a double layer of security, using both the user's distinctive voice characteristics and their personal password. As users select their own password, the RSV100 is language independent and is suitable for use by any user, including children.

The RSV100 is intended for a group of users, each selecting their own password. As a result, the selected passwords are stored in a separate memory chip, hence providing for a larger number of users.

The RSV100 has very low power consumption and is ideal for integration into power sensitive and battery-operated devices, where minimal power consumption is critical.

The RSV100 applies proprietary speech analysis and comparison technology to create representative, yet efficient speech templates. Sophisticated speech comparison algorithms detect the presence of speech and compare it to the stored template, resulting in highly accurate speaker identification process.

The RSV100 Developer's Kit comes with a comprehensive, fully documented integration package which includes an evaluation board, a PC-based software utility to communicate with the evaluation board, reference design and datasheet.
