Modify speech commands

We recommend using MultiNet6 or newer models.
Here's a simple example to modify speech commands in the code.
You can also modify the default command list, please refer to document for more details.

// MultiNet6
    // Note: Please create multinet handle before adding speech commands

    esp_mn_commands_clear();                       // Clear commands that already exist 
    esp_mn_commands_add(1, "turn on the light");   // add a command
    esp_mn_commands_add(2, "turn off the light");  // add a command
    esp_mn_commands_update();                      // update commands
    multinet->print_active_speech_commands(model_data);     // print active commands
