# Rook Multi Speaker

> Perceptual speech enhancement for natural-sounding human conversation.

The Rook Multi Speaker models are specifically optimized for **human-to-human** interaction in real-time constrained systems (e.g. voice calls).
They reduce background noise and reverberation while preserving speech naturalness and intelligibility for human perception.

In contrast to the Quail models, Rook Multi Speaker will suppress any sound that is does not recognize as speech.
This makes Rook Multi Speaker suitable also as a pre-processing step for third-party VADs that do not perform well in noisy conditions.
However, note that Rook Multi Speaker will preserve both foreground and background speech.
