Open the original- What it measures
- MultiNet is an offline model for short fixed phrases, such as turning on a light, that runs on Espressif's ESP32-S3 and newer chips. It does not transcribe open dictation.
- What it does not show
- A command list, not free speech. Espressif's wording and limits change between releases, and an older overview page gave a lower command count.
