Android(RecognitionListener) 实时语音转文本预览 [英] Android( RecognitionListener) live speech to text preview

问题描述

我在我的应用程序中使用识别侦听器界面将语音转换为文本.但是，我想在我说话时立即显示语音转换后的文本.如果我说 4-5 个单词，那么我一说第一个单词就应该显示出来.总之就像谷歌助手.我目前正在覆盖它的 onresults 方法并在调用此方法时显示结果.有没有办法一次检测一个单词并一个一个显示出来?

I'm using recognitionlistener interface in my app to convert speech to text. However I want to display the converted text from speech as soon as I speak. If I speak 4-5 words then 1st word should be displayed as soon as I speak it. In short like google assistant. I'm currently overriding it's onresults method and showing results when this method is called. Is there any way to detect one word at a time and show it one by one?

推荐答案

是的，你可以，你需要覆盖 onPartialResults :)

Yes you can, you need to override 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);
            }
