Voiceprint Commands

The following voice commands are employed in conjunction with voiceprint

authentication. For a more detailed description of their use, see the User's

Guide:

• Record Voiceprint

• Erase Voiceprint

• Erase Voiceprint Of <User Name>

These commands are all conditioned upon enabling of the voiceprint mechanism

as described above, as well as the corresponding permissions.

Note: If users have already recorded a voiceprint, they cannot re-record the

voiceprint unless they also have the Erase Your Voiceprint permission.

Recommendations for Using Voiceprints

Leave voiceprints disabled until your users have gained familiarity with the rest of

the system. At that point, you can activate authentication from the User

Registration page of the System screen in the Administration Console.

If the users who require authentication fall into existing groups—for example,

the Doctors group and the Nurses group—you can set the necessary voiceprint

permissions as properties of Doctors and Nurses. If existing groups also include

users who do not require authentication, you may want to set up a special group

that includes only users who require authentication.

Important: Users must record voiceprints in a quiet environment.

Authentication accuracy degrades for voiceprints recorded in the presence of

noise.

Because authentication entails a certain degree of user inconvenience, you

should enable authentication only for those users who need it.

• If authentication is needed for only a few people in the organization, it is

best to leave Auto-Record Voiceprints disabled and instruct those few

people to record their voiceprints explicitly using the Record Voiceprint

command.

• If, on the other hand, everyone will need to be authenticated, it may be

better to turn on Auto-Record to force users to record a voiceprint at the

time of their next login. The disadvantage of Auto-Record is that it may

prove distracting if it intrudes at an inopportune time.
