Open the original- What it measures
- The table sits in the README of the esp-sr component, version 2.6.0. It shows which chips each speech recognition model supports. The Audio Front End table lists the original ESP32 separately.
- What it does not show
- A missing row is not a statement that the chip cannot run the model. Check the esp-sr documentation for your chip and SDK version before you design around it.
