The useful part

8 voice AI UX patterns Mapping emerging Voice AI UX patterns, perceived agent roles, key design decisions and limitations Radio Rex (1922) was the first voice-activated toy ever sold. When you said "Rex," the sound energy of the letter "x," around 500 Hz, vibrated the metal bridge and interrupted the current. A simple mechanism, triggered by nothing more than a fixed frequency and it must have seemed almost magical at the time.

How it works

  • Decades of voice-enabled toys, robots and digital assistants works on the same basic principle Rex did, i.e to detect a sound pattern, match it to intent and then trigger a response.
  • This idea barely changed for most of the century that followed.
  • More recently, rapid gains in performance, cost, reliability, and latency of large language models and speech models have reshaped voice as a medium, unlocking new use-cases and interaction patterns for...
