New X2-NativeCursor system improves text-to-speech progress tracking

By PulseAugur Editorial · [1 sources] ·

Researchers have developed X2-NativeCursor, a novel system for tracking text progress in incremental text-to-speech (TTS) applications. This lightweight observer operates by analyzing native speech tokens before waveform decoding, enabling more accurate synchronization for features like highlighting and interruption handling. The system demonstrates significantly lower tracking error and improved real-time performance compared to existing waveform-based methods, and has been validated on models like Qwen3-TTS and CosyVoice2. AI

IMPACT Enhances real-time capabilities for TTS systems, improving user experience in applications requiring synchronized text and speech.

    X2-NativeCursor: Native-Token Text Progress Tracking for Incremental-Text Streaming Codec TTS

    arXiv:2609.09677v1 Announce Type: new Abstract: Incremental-text streaming text-to-speech (TTS) needs online text progress tracking for synchronized highlighting, interruption handling, and dialogue-history updates. Input text arrives before it is spoken, so text arrival alone ca…
