Android（RecognitionListener）現場演講文本預覽

Question

我在我的應用程序中使用recognitionlistener界面將語音轉換爲文本。不過，我想在演講後立即顯示來自演講的轉換文本。如果我說4-5個單詞，那麼只要我說一個單詞就應該顯示第一個單詞。總之就像谷歌助理。我正在重寫它的onresults方法並顯示調用此方法時的結果。有沒有辦法一次檢測出一個單詞並逐一顯示？

當然可以，你需要重寫onPartialResults :)

@Override 
      public void onPartialResults(Bundle partialResults) { 
       ArrayList data = partialResults.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION); 
       String word = (String) data.get(data.size() - 1); 
       recognisedText.setText(word); 

       Log.i("TEST", "partial_results: " + word); 
      }
