大家好，我是語音辨識開發的初初入門使用者，先感謝大家的協助。
我在 Edge Impulse 網站訓練了關鍵詞語音模型，下載 Quantized (int8) 或 Unoptimized (float32) 的 .tflite 檔並使用 Ameba_acuity_toolkit 順利產生 .nb 檔，
但是在 Arduino IDE 中使用 AudioClassification 範例來測試載入 .nb 檔時，Serial Monitor 最後就是不斷出現 not align to 0x20 的錯誤資訊。
請問是否在編輯 marabari_va_inputmeta.yml 檔案時，針對關鍵詞語音辨識有一定的設定規則呢?
還是在 Edge Impulse 網站產生特徵或是訓練模型應該注意那些細項呢？
已測試了在 Edge Impulse 嘗試各種提取特徵的組合 MFCC, MFE, classifler, keyword-spotting 等等，然後訓練生成各種模型，並在AI的協助下修改各種版本的 marabari_va_inputmeta.yml 來匯出 .nb 檔。
