一、在语音识别中可以正常运行，唤醒也可以用，但是当判断是什么唤醒词语的时候出错？

解决方式：JSONObject jsonObject=new JSONObject(params);String word=jsonObject.getString(“word”);放到判断语句中即可解决

public void onEvent(String name, String params, byte[] data, int offset, int length) {
        txtResult.setText(name);
        try {
            if ("wp.data".equals(name)) {
                JSONObject jsonObject=new JSONObject(params);
                String word=jsonObject.getString("word");
                if (word.equals("陌途陌影")){
                    Toast.makeText(this, "唤醒成功啊", Toast.LENGTH_LONG).show();
                }
                // 识别相关的结果都在这里
                Log.d("唤醒","唤醒成功");
            }
            else{
                Toast.makeText(this,"唤醒失败",Toast.LENGTH_LONG).show();
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

    }
