Talk Title: In human-likeness we trust? Human-like speech synthesis and and the challenges of speech design and evaluation
Talk Abstract: Speech synthesis is a core part of any speech based conversational interface. It is arguably one of the most important aspects that we must consider as designers when creating speech based conversational machines. My keynote will explore how the frequent goal of human-likeness in synthesis influences user behaviour and perceptions of a speech agent’s capability as a dialogue partner (termed partner models), how the focus on emulating human voices may be misguided as well as how we can bridge the gaps between the speech technology and conversational user interfaces communities by jointly tackling key challenges in the evaluation of synthetic speech.
