Simple example of iFlytek java speech recognition sdk

1. The official website of iFLYTEK provides a more complete Demo

2. My Demo has deleted the rest of the parts except speech recognition, which is convenient to get started quickly

3. The whole project is in the attachment

4. The lambda expression is used, which requires java8 to run

5. The code is as follows:

package com.iflytek;

import java.awt.BorderLayout;
import java.awt.Container;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextArea;

import com.iflytek.cloud.speech.SpeechConstant;
import com.iflytek.cloud.speech.SpeechError;
import com.iflytek.cloud.speech.SpeechRecognizer;
import com.iflytek.cloud.speech.SpeechUtility;
