Krisp’s new listener-side accent conversion adapts incoming speech in real time to improve comprehension for listeners.

Krisp now offers a listener-side accent conversion feature that refines incoming accented English during live calls, preserving the speaker’s natural voice and tone. The processing happens locally with imperceptible latency, so only listeners hear the adapted audio without affecting how speakers sound. This feature is available today in Krisp’s Voice AI for Meetings app on Mac and Windows, and is being added to Call Center AI and the SDK. It’s trained on a wide range of English accents—Indian, Filipino, Latin American, African, and Chinese Mandarin—with more coming.

Key Points:

  • Processes incoming speech to clarify misheard phonemes in real time

  • Runs locally on-device with under 200 ms latency for seamless experience

  • Preserves speaker’s voice identity while improving intelligibility

  • Available now in Krisp Voice AI for Meetings on Mac and Windows

Takeaway: By shifting accent adaptation to the listener’s end, Krisp removes communication friction without changing how people speak, enabling clearer, more natural interactions for global teams and voice AI agents.
