The consortium ECESS (European Center of Excellence for Speech Synthesis) has set up a framework for evaluation of software modules and tools relevant for speech synthesis. Till now two lines of evaluation campaigns have been established: (1) Evaluation of the ECESS TTS modules (text processing, prosody, acoustic synthesis). (2) Evaluation of ECESS tools (pitch extraction, voice activity detection, phonetic segmentation). The functionality and interfaces of the ECESS TTS have been developed by a joint effort between ECESS and the EC-funded project TC-STAR . First evaluation campaigns were conducted within TC-STAR using the ECESS framework. As TC-STAR finished in March 2007, ECESS continued and extended the evaluation of ECESS TTS modules and tools by its own. Within the paper we describe a novel framework which allows performing remote evaluation for modules via the web. First experimental results are reported. Further the result of several evaluation campaigns for tools handling pitch extraction and voice activity detection are presented.
