Deutsche Telekom AG is pleased to see the W3C Extensible Multimodal Annotation markup language 1.0 (EMMA) recommendation moving forward and is happy to support the process by providing the following implementation report.

We made use of EMMA within various multimodal prototype applications. Among others, EMMA documents have been generated from within VoiceXML scripts using ECMASrcipt and sent to a server-based Interaction Manager (see MMI architecture for more details http://www.w3.org/TR/mmi-arch). The Interaction Manager - implemented using an early version of an SCXML interpreter (see http://www.w3.org/TR/SCXML) - acted as an EMMA consumer and integrated input (represented using EMMA) from various modalities. EMMA documents have also been used for communication between various dialog management modules.

From our implementation experiences we note that EMMA has proven to be a valuable specification for representation of (multimodal) user input.
