Voice AI has progressed from basic transcription to systems that can listen and speak at the same time, but industry executives say that still falls short of a broader breakthrough. TechCrunch reports that PolyAI CTO Shawn Wen sees faster reasoning as the next hurdle: models need to retrieve answers quickly enough to keep a conversation feeling natural.
Trust depends on what happens after speech
Wen said customer-service agents also need to sound less robotic and prove they can solve a caller’s problem. In his view, confidence can build over the first two or three exchanges, reducing the need to hand the call to a human.
Otter CMO Alex Gay pointed to a different stack of requirements for meetings: identifying speakers, capturing intent and connecting transcripts with organizational knowledge. Otter is also working on digital twins that could represent people in meetings, though Gay said those systems need enough emotional expression to support debate and strategic discussion rather than behaving like simple question-and-answer bots.
