Vocally and Aldebaran has provided a first version of the functions of echo cancellation, noise reduction and sound localization. They have built a corpus of audio signals that will be used to model the audio system of Nai and to evaluate the performances of the developed functions. The integration on Nao was delayed because it is not possible to make a synchronized acquisition of the input and the output audio buffers. This synchronization is necessary for the echo cancellation function in which the robot is supposed to cancel its own voice in the audio signal acquired by its microphones. Aldebaran has developed standalone software to overcome this problem. It will allow the testing of the Vocally function.
