barge-in
In voice interaction, the act of a user intentionally interrupting the speaker to gain the floor, expressing "please stop, it is my turn." Its pragmatic intent is entirely distinct from that of a backchannel, which serves as a feedback signal.
Timeline (last 90 days)
Implementing barge-in requires audio echo cancellation (AEC) of the sound the system itself plays; otherwise, the system will mistake its own output for user input.
Backchannel refers to the brief responses emitted by the listener while the other party continues speaking (such as 'uh-huh' and 'right'), while barge-in refers to intentionally interrupting; the pragmatic intents of the two are entirely different.
Voice AI needs to handle barge-in: when a user interrupts while the AI is speaking, the system must immediately stop and respond.
Barge-in capability is one of the core metrics for measuring whether a voice AI has reached production grade.
When the user speaks while the system is reading out a response, recognition quality degrades noticeably, requiring a dedicated barge-in mechanism to address this.
