Four voice SDKs, one shared runtime, zero cloud

Quick update from the VoxRT team. On Sept 19 we are launching VoxRT Voice AI Runtime here on Product Hunt. Each model ships as its own SDK. All of them are built on the same VoxRT runtime. That keeps latency profiles, memory behavior, and platform bindings consistent across the stack.

Wake-Word shipped earlier this month as a standalone product. This launch introduces the rest of the SDKs alongside it.

What's launching:

• Wake-word "Hey Assistant" (100 KB, 5.3% RTF on Raspberry Pi Zero 2 W)

• Silero VAD on our runtime (3.05% RTF on mid-range Android)

• 14-command keyword spotting (16% RTF on Snapdragon 662, 0.97% RTF in Chrome WASM)

• Streaming ASR (NeMo FastConformer): partial results, real-time on mid-range mobile

TTS is next up, in development, shipping after this launch.

Runs on-device across iOS, Android, browser (WASM), and Raspberry Pi. Coverage varies per SDK.

If any of this is relevant to what you are building, hit Notify Me on the product page so you catch the launch.
