Title of the intervention:

Towards helpful, customer-specific Text-To-Speech synthesis

Abstract of the intervention:

The subject of automatic speech synthesis began to democratize in the 1990s. Each of us has already dealt with those automated answering machine voices that initially made us all suffer. Today, however, the advances made in both understanding language and the acoustic quality of speech synthesis approaches have allowed us to make giant leaps, and new voice services are currently seeing their quality and capabilities rapidly increase with voices that are ever more human and expressive.
In this presentation, we will briefly review recent advances in speech synthesis. After this introduction, we will address topics related to customizing synthetic voices to meet client needs at several levels. First, at the level of the main components of spoken expression: language, speech style, language register, and gender, for example. Then, the issues related to the utterance; primarily prosodic (manipulation of pitch, rate). Finally, we will conclude by discussing subsidiary elements to consider in order to best meet the needs of clients and end users of synthetic voices in our constantly evolving world.
