Laughter / Rire

The Monash University (Melbourne) has also tried to perform laughter recognition, which is a "side-effect" of the SoundHunter software. For the moment, the laughter-recognition software is rather crude and cannot accurately distinguish between different people.
L'université de Monash (Melbourne) a également essayé la reconnaissance par le rire, mais pour l'instant ce n'est qu'un "effet de bord" de leur software SoundHunter, qui est plutôt simpliste et ne peut pas encore reconnaître les gens avec précision.
