The Voice Summary Shrinks—and Does Not Win
A glanceable mobile display reduced conversations to short phrases, but 48 participants resumed them no better than with a transcript.
Summary
A glanceable mobile display reduced conversations to short phrases, but 48 participants resumed them no better than with a transcript.
Souffleur was designed to preserve the thread of a mobile voice conversation after an interruption by showing a few short phrases instead of a text chat. In a between-subjects study with 48 participants, the system showed no reliable difference from a conventional transcript in ease of following or resuming short conversations, effort, attention or recall. That null result matters: a compact interface can reduce visible text without automatically improving conversational continuity.
