先看效果：

代码实现：

1.先下载sdk,然后进行解压，放到对应的文件夹中，

2.写一个语音工具类：

AudioUtils:

package com.example.administrator.liujie;import android.content.Context;import android.os.Bundle;import android.util.Log;import com.iflytek.cloud.InitListener;import com.iflytek.cloud.SpeechConstant;import com.iflytek.cloud.SpeechError;import com.iflytek.cloud.SpeechSynthesizer;import com.iflytek.cloud.SynthesizerListener;/** * Created by Administrator on 2017/12/1. */public class AudioUtils {    private static AudioUtils audioUtils;    private SpeechSynthesizer mySynthesizer;    private AudioUtils() {    }    /**     * 描述:单例     */    public static AudioUtils getInstance() {        if (audioUtils == null) {            synchronized (AudioUtils.class) {                if (audioUtils == null) {                    audioUtils = new AudioUtils();                }            }        }        return audioUtils;    }    private InitListener myInitListener = new InitListener() {        @Override        public void onInit(int code) {            Log.d("mySynthesiezer:", "InitListener init() code = " + code);        }    };    /**     * 描述:初始化语音配置     */    public void init(Context context) {        //处理语音合成关键类        mySynthesizer = SpeechSynthesizer.createSynthesizer(context, myInitListener);        //设置发音人        mySynthesizer.setParameter(SpeechConstant.VOICE_NAME, "xiaoyan");        //设置音调        mySynthesizer.setParameter(SpeechConstant.PITCH, "50");        //设置音量        mySynthesizer.setParameter(SpeechConstant.VOLUME, "50");    }    /**     * 描述:根据传入的文本转换音频并播放     */    public void speakText(final String content) {        int code = mySynthesizer.startSpeaking(content, new SynthesizerListener() {            //开始播放            @Override            public void onSpeakBegin() {            }            //缓冲进度回调            @Override            public void onBufferProgress(int i, int i1, int i2, String s) {            }            //暂停播放            @Override            public void onSpeakPaused() {            }            //恢复播放回调接口            @Override            public void onSpeakResumed() {            }            //播放进度回调            @Override            public void onSpeakProgress(int i, int i1, int i2) {            }            //会话结束回调接口            @Override            public void onCompleted(SpeechError speechError) {            }            @Override            public void onEvent(int i, int i1, int i2, Bundle bundle) {            }        });    }}

3.MainActivity:

package com.example.administrator.liujie;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;import com.iflytek.cloud.RecognizerResult;import com.iflytek.cloud.SpeechConstant;import com.iflytek.cloud.SpeechError;import com.iflytek.cloud.SpeechUtility;import com.iflytek.cloud.ui.RecognizerDialog;import com.iflytek.cloud.ui.RecognizerDialogListener;import org.json.JSONArray;import org.json.JSONObject;import org.json.JSONTokener;public class MainActivity extends AppCompatActivity implements View.OnClickListener {    private Button btn_click;    private Button btn_open;    private EditText mResultText;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        btn_click = (Button) findViewById(R.id.btn_click);        btn_open = (Button) findViewById(R.id.btn_open);        mResultText = ((EditText) findViewById(R.id.result));        SpeechUtility.createUtility(this, SpeechConstant.APPID + "= 5a20e5b4");        btn_click.setOnClickListener(this);        btn_open.setOnClickListener(this);    }    @Override    public void onClick(View v) {        switch (v.getId()) {            case R.id.btn_click:                btnVoice();                break;            case R.id.btn_open:                AudioUtils.getInstance().init(MainActivity.this); //初始化语音对象                String s = mResultText.getText().toString();                AudioUtils.getInstance().speakText(s); //播放语音                break;        }    }    //TODO 开始说话：    private void btnVoice() {        RecognizerDialog dialog = new RecognizerDialog(this, null);        dialog.setParameter(SpeechConstant.LANGUAGE, "zh_cn");        dialog.setParameter(SpeechConstant.ACCENT, "mandarin");        dialog.setListener(new RecognizerDialogListener() {            @Override            public void onResult(RecognizerResult recognizerResult, boolean b) {                printResult(recognizerResult);            }            @Override            public void onError(SpeechError speechError) {            }        });        dialog.show();        Toast.makeText(this, "请开始说话", Toast.LENGTH_SHORT).show();    }    //回调结果：    private void printResult(RecognizerResult results) {        String text = parseIatResult(results.getResultString());        // 自动填写地址        mResultText.append(text);    }    public static String parseIatResult(String json) {        StringBuffer ret = new StringBuffer();        try {            JSONTokener tokener = new JSONTokener(json);            JSONObject joResult = new JSONObject(tokener);            JSONArray words = joResult.getJSONArray("ws");            for (int i = 0; i < words.length(); i++) {                // 转写结果词，默认使用第一个结果                JSONArray items = words.getJSONObject(i).getJSONArray("cw");                JSONObject obj = items.getJSONObject(0);                ret.append(obj.getString("w"));            }        } catch (Exception e) {            e.printStackTrace();        }        return ret.toString();    }}

4.activity_main:

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.administrator.liujie.MainActivity">    <Button        android:id="@+id/btn_click"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="点击打开语音识别" />    <EditText        android:id="@+id/result"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_below="@id/btn_click"        android:hint="此处显示你所录下的内容" />    <Button        android:id="@+id/btn_open"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/result"        android:text="播放语音" /></RelativeLayout>

5.权限：

<uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.CAMERA" />

6.效果就实现了。本人写了好几次才写对。
