M5Stack ASR Unit with Offline Voice Module (CI-03T)
Grove-connected unit whose product name states offline automatic speech recognition on a CI-03T module. The command set, supported languages, wake-word behaviour and host integration path were NOT verified against a datasheet in this pass. Treat the offline-ASR claim as a supplier claim until the datasheet is read.
