Research notes,
with an operator.
This information and tools site is operated by Jianming Duan (段建明). It tracks public speech-model releases and develops Local Voice Dock.
Who makes this site

How we verify
Each page includes a source list and a last-verified date. We use publisher pages for release facts, preserve unknowns where no public documentation was found, and separate model capabilities from capabilities we have actually tested. A statement about a demonstration is not a benchmark or a performance guarantee.
Corrections and contact
Email duanjianming1981@gmail.com with the page URL, the statement in question and a source supporting the correction. For product feedback, describe the Mac, operating-system version and steps that produced the issue. Do not send private recordings, passwords or API keys.
Commercial scope
Free reservations collect interest in a separate Mac software product. A US$1.90 refundable preorder for our separate Local Voice Dock launcher is being prepared. Purchasing is disabled pending payment, refund and independent acceptance checks. It does not buy a Block product or Dessa access. See the preorder terms. No affiliate commission link is currently active. If commercial placements are introduced, their relationship will be disclosed next to the recommendation.
Sources and trademarks
Product names identify their respective developers. We use a separate text-led design and do not reproduce Block or Dessa logos. Publisher demos stay on publisher pages.
