VOCAL SCW 1 checks the codeword
and the unique voice-pattern.
Any voice-pattern is just as unique as a fingerprint.
Speak your codeword into the microphone or use a dialer.
Via the speaker you will be prompted or get answers.
VOCAL SCW 1 recognises you and
up to another 4 authorised drivers by biometrical voice identification
as well as the codeword. Only then does it allow the vehicle
to be started.
