We propose a novel approach that utilize inter-speaker relative cues for distinguishing target speakers and extracting their voices from mixtures. Continuous cues (e.g., temporal order, age, pitch level) are grouped by relative differences, while discrete cues (e.g., language, gender, emotion) retain their categories. Relative cues offers greater flexibility than fixed speech attribute classification, facilitating much easier expansion of text-guided target speech extraction datasets. Our experiments show that combining all relative cues yields better performance than random subsets, with gender and temporal order being the most robust across languages and reverberant conditions. Additional cues like pitch level, loudness, distance, speaking duration, language, and pitch range also demonstrate notable benefit in complex scenarios. Fine-tuning pre-trained WavLM Base+ CNN encoders improves overall performance over the baseline of using only a Conv1d encoder.
