### Answer Yes, Retell AI offers a denoising mode specifically designed to remove background speech from the user's audio. [(1) ]() ## Denoising Modes You have two options: - Remove noise (default) – Removes background noise with nearly no distortion to the waveform and no impact on speech-to-text accuracy, but cannot remove loud background speech. - Remove noise + background speech – A more aggressive mode that removes both background noise and background speech. This may distort the waveform and can result in lower speech-to-text accuracy in certain cases. This option incurs a $0.005/min surcharge. If your use cases typically have loud background speech (like a TV or other speakers nearby) , try the

remove noise + background speech

mode. ## Additional Tuning You can also lower the interruption sensitivity setting to make the agent more resilient to background speech. Setting it lower (e.g., 0.8) helps reduce false interruptions from other voices. The

denoising_mode

parameter can be set via the API with these options:

none

,

noise-cancellation

, or

noise-and-background-speech-cancellation
