# NeuroXess **Entity class:** Brain-computer interface company **Domain:** Flexible Electrode Interfaces / Chinese Speech Decoding **Doc Type:** Company Node **Maturity:** Clinical-stage **Collection:** [[collections/Neurotech|Neurotech]] **Primary Sources:** [[research/Research Inferences Integration Report - 2026-10-23|Research Inferences Integration Report — 2026-10-23]] ## Definition **NeuroXess is a Shanghai company developing high-channel flexible-electrode brain-computer interfaces, and the first group to demonstrate real-time decoding of Mandarin Chinese from neural activity.** It was founded by Tiger H. Tao, whose team worked with Jinsong Wu at Huashan Hospital on a December 2024 clinical trial using a 256-channel implant in a patient with epilepsy. The results were published in *Science Advances* on 5 November 2025. ## Record - **Speech decoding:** about 71% accuracy across 142 common Chinese syllables within five days of surgery, at under 100 milliseconds of single-character latency, reaching coverage of 418 syllables within a week. - **Combined decoding:** the company has announced results joining motor and language decoding in one system. - **Platform:** a 256-channel fully implantable wireless system demonstrated for cursor control, robotic interaction and Mandarin speech decoding, per a mid-2026 industry survey. - **Regulatory:** a landscape analysis reports that a semi-invasive BCI from the Huashan and NeuroXess group received NMPA Class III approval on 13 March 2026, the same date as [[wiki/Neuracle|Neuracle]]'s NEO. That is a single source and concerns a semi-invasive device rather than the speech system; it awaits confirmation against the registration record. - **Unverified:** an encyclopedia-style source reports output above 300 characters a minute in 2026, exceeding normal Mandarin speech rate; no primary source was located. ## Reading NeuroXess is the strongest evidence for the register's claim that substantial neural-interface programs run outside the American reporting environment with their own trials, companies and publication record. Its speech work also tests a question the English-language programs cannot: whether decoding transfers across a tonal, syllable-based language, where the unit inventory and the role of pitch differ from English phoneme decoding. The company operates inside the national plan that targets clinical and commercial BCI deployment by 2027. ## Open Questions - Primary confirmation of any NMPA registration, and for which device. - Peer-reviewed accuracy and latency for open-vocabulary Mandarin outside the laboratory. - Whether the 300-characters-a-minute figure holds against a published measurement. ## Research Inferences These entries translate the forward-looking register in [[research/Research Inferences|Research Inferences]] into ordinary wiki prose. The tier labels apply to the inference, not automatically to every factual anchor inside it. Proposed IDs above INF-0500 come from the 2026-10-23 cycle: [[research/Research Inferences Integration Report - 2026-10-23|Research Inferences Integration Report — 2026-10-23]] · [[research/Research Inferences Integration Audit - 2026-10-23|Research Inferences Integration Audit — 2026-10-23]]. - **INF-0465 — Strongly indicated.** Substantial neural-interface and brain-mapping programs operate outside the American reporting environment, with their own trials, companies, and standards participation. Visibility in English-language press is not a measure of capability, and native-language sourcing is required for an accurate picture. - **INF-0007 — Strongly indicated.** Academic speech BCIs reached 62–78 words per minute with implanted electrodes and model-side decoding, which means the recent gains are attributable to the decoder more than the sensor. Decoder improvement is free of surgical risk and compounds across every existing implant already in a head. - **INF-0002 — Plausible.** Paradromics frames Connexus against transcribed human speech at roughly 40 bps, a comparison that sets the commercial floor at parity with talking. The interesting regime opens above it: once decoded output exceeds speech rate, the interface stops substituting for a lost channel and becomes a channel humans never had. - **INF-0083 — Strongly indicated.** Work through 2026 has moved from decoding externally supplied captions toward recovering participants' own inner speech via subject-specific neural-semantic alignment. Inner speech is the first genuinely private content to become instrumentable, and the technique requires no change to the underlying language model. - **INF-0367 — Strongly indicated.** Clinical programs migrate toward jurisdictions with faster pathways, which relocates the evidence base for frontier interventions. Reading where trials are run is the most reliable indicator of where a capability will first become ordinary. ## Relationships - **founder:** Tiger H.
