MENGENAI EPISOD INI
Dylan Fox is the founder and CEO of AssemblyAI, the voice AI infrastructure platform behind AI notetakers, medical scribes, drive through ordering, contact centers and humanoid robots. AssemblyAI went through Y Combinator's first AI batch in 2017 and now serves over 1 million developers with roughly 100 million API calls a day.
We get into the volume numbers, why weekly conversations are up over 800% in three years, the three macro trends pulling voice into everything, why coding agents turned small businesses into API customers, how data mixture drives 75% of model quality, the humanoid robot speaker problem, on device models, and the disclosure question the entire voice agent industry is avoiding.
"It's very easy to optimize for a public open source benchmark. It's very hard to optimize across all these real world applications."
We cover
› 120 million weekly conversations and 4x YouTube's daily voice volume
› Coding agents expanding the TAM by 100x
› Context aware voice models and the McDonald's ordering problem
› Why humanoid robots can't disambiguate speakers
› Whether voice agents should disclose they are AI
