Demo · Paralinguistic Expressiveness
Emotion & Speaking Style

Same Thinker; vanilla Talker vs. Silent Tags. All inputs are spoken queries — responses are generated end-to-end with no explicit tags at inference.

Demo · Intra-Response Trajectory
Token-Free Prosody Shift Within a Single Response

Silent tags re-read the Thinker's hidden states at every decoding step, so a reply can open soothingly and pivot to an encouraging tone mid-sentence — no inline tags inserted.

Scenario Response (prosody labels shown for reference only) Baseline (Qwen2.5-Omni) Silent Tags
User distressed about a setback soothing "I hear you — that's genuinely hard, and it's okay to feel overwhelmed." encouraging "But you've navigated tough situations before, and you have more tools than you realise."
User shares exciting news nervously warm "That's wonderful news — congratulations!" excited "I can only imagine how much work went into this. You should be really proud!"
Sarcastic question about obvious advice dry "Yes, drinking water when you're thirsty is indeed recommended." playful "But in all seriousness, hydration has measurable effects on focus — want the details?"
Additional demo cases (longer conversations, more emotion categories, and out-of-domain scenarios) will be appended here in subsequent revisions.
