Speaker Adaptation (SA) mode

Speaker Adaptation allows up to two out-ofdialect users to train the system to improve recognition accuracy. By repeating a number of commands, the users can create a voice model of their own voice that is stored in the system. The system is capable of storing a different speaker adaptation model for each connected phone.
