X2-NativeCursor is proposed, a lightweight observer that tracks progress from native speech tokens before waveform decoding without changing the TTS generator, and its normalization plan links spoken labels to their original-text spans.
A frame-synchronous turn state head that operates in parallel with the ASR head on shared streaming representations, jointly predicting ASR tokens and fine-grained turn states at the frame level is introduced.

X2Streaming-ASR is proposed, which decomposes streaming recognition into when to commit and what to commit, and achieves the best streaming CER among the evaluated systems on AISHELL-1 and AISHELL-3 with substantially lower latency.

X2Streaming-TTS is presented, a causal TTS framework that consumes asynchronously arriving text tokens and emits speech without accessing future input that outperforms existing pseudo-streaming models on most subjective and objective metrics.
