Advances in Single‑Channel Speech Separation and Target Speaker Extraction with Iterative Refined Adaptation

The article surveys recent advances in single‑channel speech separation and target‑speaker extraction, explains the encoder‑separator‑decoder framework, compares frequency‑ and time‑domain methods, highlights models such as SpEx+, DPRNN‑Spe, and introduces Iterative Refined Adaptation, which iteratively improves speaker embeddings to boost SI‑SDR performance and enables effective speaker‑suppression for applications like in‑vehicle voice interaction.
