Tips for Using the Speaking Lab

The Speaking Lab tool reacts differently to different kinds of voices.

Background noise affects the accuracy of the Speaking Lab tool. The SR engine is more
    likely to confuse similar-sounding words such as out and pout, or in and when. Try to use
    the Speaking Lab tool in a quiet room.

Check the sound level of the microphone.

Speak in a loud and clear voice.
