Welcome

The Speech Synthesis Workshop (SSW) is the main meeting place for research and innovation in speech synthesis, i.e. predicting speech signals from text input. Text-to-Speech (TTS) technology is a key component of numerous applications: speech-to-speech translation, digital assistants, conversational agents, social robots. While early research focused on basic intelligibility, contemporary systems now achieve remarkable naturalness. Current research frontiers include emotional expression, speaking style control, and efficient deployment for the world’s languages.

SSW welcomes contributions not only in the core TTS technology but also gathers researchers from contributing sciences: from phoneticians, phonologists, linguists, neuroscientists to experts of multimodal human-machine interaction.

Since 1990, SSWs are held every three years under the auspices of ISCA‘s special interest group SynSIG. In 2019, it was decided to have an SSW every two years, since the technology is advancing faster these days.

The 14th ISCA Speech Synthesis Workshop will be held in Maceió, Brazil, 6 (Mon)- 8 (Wed) Sept 2027. The workshop is a satellite event of the INTERSPEECH 2027 conference (São Paulo, Brazil).
