Open the original- What it measures
- Espressif says developers reach these instructions through its ESP-DSP and ESP-NN libraries. The original ESP32 product line is not described as having the same support on this page.
- What it does not show
- This is a vendor's description of hardware acceleration. It does not give a speed-up for any speech model, so measure a model on the board before you rely on it.
