Sesame's blog post discusses the challenges of creating natural-sounding conversational AI voices. It argues that simply improving the acoustic quality of synthetic speech isn't enough to overcome the "uncanny valley" effect, where slightly imperfect human-like qualities create a sense of unease. Instead, they propose focusing on prosody – the rhythm, intonation, and stress patterns of speech – as the key to crafting truly engaging and believable conversational voices. By mastering prosody, AI can move beyond sterile, robotic speech and deliver more expressive and nuanced interactions, making the experience feel more natural and less unsettling for users.
HN users generally agree that current conversational AI voices are unnatural and express a desire for more expressiveness and less robotic delivery. Some commenters suggest focusing on improving prosody, intonation, and incorporating "disfluencies" like pauses and breaths to enhance naturalness. Others argue against mimicking human imperfections and advocate for creating distinct, pleasant, non-human voices. Several users mention the importance of context-awareness and adapting the voice to the situation. A few commenters raise concerns about the potential misuse of highly realistic synthetic voices for malicious purposes like deepfakes. There's skepticism about whether the "uncanny valley" is a real phenomenon, with some suggesting it's just a reflection of current technological limitations.
