Vocally and Aldebaran still work on improving their own echo cancellation, noise reduction and sound localization algorithms. Since few time, a new speech recognition engine has been integrated on Nao, which allows to have 95% of recognition rate when the speaker is saying words at 1m of the robot, even with important fan noise. It has been decided that the recognition of the short orders said to the robot will be made directly with this embedded recognition engine. To improve the natural language understanding by the robot, a recognition engine based on a remote server will be used. The  improvments achieved by vocally on the performances of this engine will soon be evaluated.
