二、案例介绍

第一步：首先进入讯飞开放平台注册一个账号，然后创建一个创建一个应用，命名按照你自己的想法来，会产生一个APPID，具体参考UE4如何接入科大讯飞的语音识别_ue4 科大讯飞的语音识别_飞起的猪的博客-CSDN博客

第二步：下载科大讯飞的语音转文字SDK，打开AndriodStudio运行

参考以下代码写的

private static String TAG = "TtsDemo";  // 语音合成对象private SpeechSynthesizer mTts;// 默认发音人private String voicer="xiaoyan";private String[] cloudVoicersEntries;private String[] cloudVoicersValue ;//缓冲进度private int mPercentForBuffering = 0; //播放进度private int mPercentForPlaying = 0;// 云端/本地选择按钮private RadioGroup mRadioGroup;// 引擎类型private String mEngineType = SpeechConstant.TYPE_CLOUD;// 语音+安装助手类//ApkInstaller mInstaller ;private Toast mToast;private SharedPreferences mSharedPreferences;@SuppressLint("ShowToast")public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);this.requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.ttsdemo);initLayout();// 初始化合成对象mTts = SpeechSynthesizer.createSynthesizer(this, mTtsInitListener);mSharedPreferences = getSharedPreferences("com.iflytek.setting", Activity.MODE_PRIVATE);mToast = Toast.makeText(this,"",Toast.LENGTH_SHORT);}/*** 初始化Layout。*/private void initLayout() {findViewById(R.id.tts_play).setOnClickListener(this);findViewById(R.id.tts_cancel).setOnClickListener(this);findViewById(R.id.tts_pause).setOnClickListener(this);findViewById(R.id.tts_resume).setOnClickListener(this);} @Overridepublic void onClick(View view) {switch(view.getId()) {// 开始合成case R.id.tts_play:String text = ((EditText) findViewById(R.id.tts_text)).getText().toString();// 设置参数setParam();int code = mTts.startSpeaking(text, mTtsListener);if (code != ErrorCode.SUCCESS) {if(code == ErrorCode.ERROR_COMPONENT_NOT_INSTALLED){//未安装则跳转到提示安装页面//mInstaller.install();}else {showTip("语音合成失败,错误码: " + code); }}break;// 取消合成case R.id.tts_cancel:mTts.stopSpeaking();break;// 暂停播放case R.id.tts_pause:mTts.pauseSpeaking();break;// 继续播放case R.id.tts_resume:mTts.resumeSpeaking();break;}}/*** 初期化监听。*/private InitListener mTtsInitListener = new InitListener() {@Overridepublic void onInit(int code) {Log.d(TAG, "InitListener init() code = " + code);if (code != ErrorCode.SUCCESS) {showTip("初始化失败,错误码："+code);}  }};/*** 合成回调监听。*/private SynthesizerListener mTtsListener = new SynthesizerListener() {@Overridepublic void onSpeakBegin() {showTip("开始播放");}@Overridepublic void onSpeakPaused() {showTip("暂停播放");}@Overridepublic void onSpeakResumed() {showTip("继续播放");}@Overridepublic void onBufferProgress(int percent, int beginPos, int endPos,String info) {mPercentForBuffering = percent;mToast.setText(String.format(getString(R.string.tts_toast_format),mPercentForBuffering, mPercentForPlaying));mToast.show();}@Overridepublic void onSpeakProgress(int percent, int beginPos, int endPos) {mPercentForPlaying = percent;showTip(String.format(getString(R.string.tts_toast_format),mPercentForBuffering, mPercentForPlaying));}@Overridepublic void onCompleted(SpeechError error) {if(error == null){showTip("播放完成");}else if(error != null){showTip(error.getPlainDescription(true));}}@Overridepublic void onEvent(int eventType, int arg1, int arg2, Bundle obj) {}};private void showTip(final String str){runOnUiThread(new Runnable() {@Overridepublic void run() {mToast.setText(str);mToast.show();}});}/*** 参数设置* @param param* @return*/private void setParam(){//设置合成if(mEngineType.equals(SpeechConstant.TYPE_CLOUD)){mTts.setParameter(SpeechConstant.ENGINE_TYPE, SpeechConstant.TYPE_CLOUD);//设置发音人mTts.setParameter(SpeechConstant.VOICE_NAME,voicer);}else {mTts.setParameter(SpeechConstant.ENGINE_TYPE, SpeechConstant.TYPE_LOCAL);//设置发音人 voicer为空默认通过语音+界面指定发音人。mTts.setParameter(SpeechConstant.VOICE_NAME,"");}//设置语速mTts.setParameter(SpeechConstant.SPEED,mSharedPreferences.getString("speed_preference", "30"));//设置音调mTts.setParameter(SpeechConstant.PITCH,mSharedPreferences.getString("pitch_preference", "50"));//设置音量mTts.setParameter(SpeechConstant.VOLUME,mSharedPreferences.getString("volume_preference", "80"));//设置播放器音频流类型mTts.setParameter(SpeechConstant.STREAM_TYPE,mSharedPreferences.getString("stream_preference", "3"));}@Overrideprotected void onDestroy() {super.onDestroy();mTts.stopSpeaking();// 退出时释放连接mTts.destroy();}

第三步：将下载的SDK里面的lib,srcy文件替换
