Hush: Open-source tool for suppressing background speech in voice AI calls
By
Atul Singh
Summary
The article introduces Hush, an open-source noise suppression tool built by the team at Weya to solve a critical problem in voice AI agents: background speech interference. When callers are in noisy environments (restaurants, with TVs, or people talking nearby), the AI agent misinterprets background voices as the caller's speech, derailing conversations. The tool specifically targets competing voices and ambient noise in real-time phone calls, addressing a gap they found in existing open-source noise cancellation models.

· 3 pulledThe #1 issue that kept breaking our pipeline wasn't the LLM, wasn't the TTS. It was background speech.
The background speaker's words get picked up, transcribed, and fed into the AI agent as if the caller said them. The entire conversation derails.
We tried every open-source noise cancellation model out there.
