ParaStyleTTS: Next-Gen Expressive Text-to-Speech

ParaStyleTTS introduces a lightweight, interpretable, and robust TTS framework for expressive style control directly from text prompts. It features a novel two-level style adaptation architecture that separates prosodic and paralinguistic speech style modeling, enabling fine-grained control over factors like emotion, gender, and age. This innovation overcomes limitations of LLM-based methods by achieving 30x faster inference, using 8x fewer parameters, and requiring 2.5x less CUDA memory, all while maintaining superior robustness and consistent style realization.

ParaStyleTTS introduces a novel two-level style adaptation architecture, allowing for precise and interpretable control over prosodic (phoneme-level) and paralinguistic (sentence-level) styles. This innovation ensures high-quality, robust, and controllable expressive speech.

Feature ParaStyleTTS (Our Solution) Typical LLM-based TTS (e.g., CosyVoice)
Style Control Method
  • ✓ Two-level (phoneme & sentence) explicit disentanglement
  • ✓ Acoustic-centric learning from prompts
  • ✓ Single-level implicit entanglement
  • ✓ Semantic interpretation via LLM
Robustness to Prompt Variation
  • ✓ Superior consistency across varied prompt phrasings
  • ✓ High interpretability & explicit control
  • ✓ Sensitive to prompt phrasing and wording
  • ✓ Black-box nature, harder to debug style errors
Resource Efficiency
  • ✓ 30x faster inference, 8x smaller model
  • ✓ 2.5x less CUDA memory, ideal for edge devices
  • ✓ High computational cost, substantial memory
  • ✓ Not suitable for real-time or on-device deployment

Case Study: Robust Gender Style Control

In a controlled experiment investigating robustness against prompt variation, ParaStyleTTS consistently achieved 100% accuracy in generating gender-specific speech across diverse phrasings. For example, whether prompted with "A male speaker is talking" or "You are hearing a man's voice," the model reliably produced a male voice. In contrast, LLM-based solutions like CosyVoice showed inconsistencies, with 5 out of 10 male-prompted samples being misidentified as female, highlighting its fragility. This demonstrates ParaStyleTTS's superior ability to maintain consistent style output crucial for enterprise applications requiring dependable performance.
