Issue or Suggestion Description
我使用的模组为ESP32-WROVER-E N16R8，环境为ESP-IDF V5.5.0，我尝试使用例程（cn_speech_commands_recognition）并做了修改想要直接获取模型名称但是失败了修改代码如下：
void app_main() {
models = esp_srmodel_init("model");
afe_config_t *afe_config =
afe_config_init(esp_get_input_format(), models, AFE_TYPE_SR, AFE_MODE_LOW_COST);
afe_handle = esp_afe_handle_from_config(afe_config);
esp_afe_sr_data_t *afe_data = afe_handle->create_from_config(afe_config);
afe_config_free(afe_config);
int afe_chunksize = afe_handle->get_fetch_chunksize(afe_data);
char *mn_name = esp_srmodel_filter(models, ESP_MN_PREFIX, NULL);
printf("multinet:%s\n", mn_name);
}
之后我去ESP-SR组件下似乎没有找到mn_cn2模型，build目录下也只有wn9s_hiesp目录，srmodels.bin也只有大约123KB（在sdkconfig中不勾选唤醒词的话srmodels.bin只有1KB）我怀疑是ESP-SR的mn模型是不是不支持ESP32？导致此模型并未烧入（但是sdkconfig上又有此选项所以很疑惑）
