INESC ID's Spoken Language Systems Laboratory (L²F - Laboratório de sistemas de Língua Falada) was created in January 2001, bringing together several research groups which could potentially add relevant contributions to the area of computational processing of spoken language for Portuguese. The lab is integrated in the research unit of Interactive Intelligent Systems.
