🔒DoP Deep goes deeper into the concepts and ideas that are covered in the Weekly Briefing to help you learn lessons from the experiences of top tech companies. If you’d like to upgrade to receive these in-depth pieces of analysis you can upgrade below. New reports added every month.


In a recent DoP poll, almost 50% of respondents said they interact with software through voice. I have to say, I was pretty shocked that so many people say they interact with products through voice as it’s really not something I spend much time doing day to day (aside from an occasional, often frustrating chat with Alexa).

Historically, to me at least, voice has always seemed like a UX pattern that sounds like the next big thing in theory, only to fall flat on its face in practice.

How exactly could people ever sit at their desks speaking over each other to get things done?

This is still true, but with hybrid working is perhaps less of an issue. And now, thanks to the power of LLMs and vast improvements in AI voice technologies with latency reductions, speech to speech and other technical improvements, voice is firmly back on the agenda of some of the world’s top product execs.

Just this month, Meta acquired a voice AI startup, voice generation ElevenLabs is now valued at $3.3 billion, a sizable 22% of YCombinator’s most recent startups were voice based and recent studies show 55% of Gen Z is using voice to control software.

To prove just how far AI voice technology has come, here’s this entire introduction read by my synthetic voice replica in ElevenLabs.
