Expected behavior

版本：

2.2.1

代码：
afe_config = afe_config_init(config_str, models, AFE_TYPE_SR, AFE_MODE_HIGH_PERF);
#if 1
afe_config->se_init = true;
afe_config->ns_init = true;
afe_config->afe_ns_mode = AFE_NS_MODE_NET;
afe_config->agc_init = true;
afe_config->agc_mode = AFE_NS_MODE_NET;
#endif
afe_config->vad_init = true;
afe_config->vad_mode = VAD_MODE_2;
afe_config->vad_min_speech_ms = 64;
afe_config->vad_min_noise_ms = 1000;
afe_config->agc_init = true;
afe_config->memory_alloc_mode = AFE_MEMORY_ALLOC_MORE_PSRAM;
afe_config->wakenet_init = true;
afe_config->aec_init = true;
afe_config->wakenet_model_name = esp_srmodel_filter(models, ESP_WN_PREFIX, NULL);

Actual behavior (suspected bug)

如下任务获取到的res->vad_state总是： VAD_SILENCE，但如果喊“小明同学”，唤醒一次后，就正常了，希望初始化就正常，而不是必须唤醒一次。

void audio_detect_task(void *pvParam)
{
int64_t temp_time = 0;
vad_state_t vad_state = VAD_SILENCE;
esp_afe_sr_data_t *afe_data = (esp_afe_sr_data_t *) pvParam;

/* Check audio data chunksize */
int afe_chunksize = afe_handle->get_fetch_chunksize(afe_data);
ESP_LOGI(TAG, "------------detect start------------\n");
ESP_LOGI(TAG, "afe_chunksize: %d", afe_chunksize);

//fetch一定要快，否则会出现rb_out slow
while (true) 
{
    afe_fetch_result_t *res = afe_handle->fetch(afe_data);
    vad_state = res->vad_state;

你遇到的情况比较奇怪，你可以使用下面这个例子的代码试一下，不需要唤醒也可以输出 VAD_SPEECH
