语音合成是实现人机语音交互，建立一个有听和讲能力的交互系统所必需的关键技术。
这篇文章将介绍如何使用百度Android语音合成SDK。
与语音识别SDK类似，使用语音合成SDK也需要注册，并开启语音合成API服务，详细步骤可以参考
点击打开链接 中的注册部分。
百度语音合成SDK以JAR包+动态链接库形式发布，需要开发者在
点击打开链接 下载SDK开发包，并将libs文件夹拷贝到工程中
申请必要的权限
-
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
-
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
-
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
初始化SpeechSynthesizer对象
-
speechSynthesizer = new SpeechSynthesizer(getApplicationContext(),
-
"holder", this);
-
-
speechSynthesizer.setApiKey("your-apiKey", "your-secretKey");
参数设置
-
private void setParams() {
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_SPEAKER, "0");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_VOLUME, "5");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_SPEED, "5");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_PITCH, "5");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_AUDIO_ENCODE, "1");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_AUDIO_RATE, "4");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_LANGUAGE, "ZH");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_NUM_PRON, "0");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_ENG_PRON, "0");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_PUNC, "0");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_BACKGROUND, "0");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_STYLE, "0");
-
speechSynthesizer.setParam(SpeechSynthesizer.PARAM_TERRITORY, "0");
-
}
不需要实现这么多参数，具体参数的含义可以参看SDK的使用文档和参数设置。
如果需要对音频播报的音频流进行设置，可以调用如下接口
-
speechSynthesizer.setAudioStreamType(AudioManager.STREAM_MUSIC);
以上内容即可以实现语音合成的操作，识别过程中可以使用SpeechSynthesizerListener来监听状态，从而更好的实现界面同步。
-
class listener implements SpeechSynthesizerListener {
-
-
@Override
-
public void onStartWorking(SpeechSynthesizer synthesizer) {
-
logDebug("开始工作，请等待数据...");
-
}
-
@Override
-
public void onSpeechStart(SpeechSynthesizer synthesizer) {
-
logDebug("朗读开始");
-
}
-
@Override
-
public void onSpeechResume(SpeechSynthesizer synthesizer) {
-
logDebug("朗读继续");
-
}
-
@Override
-
public void onSpeechProgressChanged(SpeechSynthesizer synthesizer, int progress) {
-
-
}
-
@Override
-
public void onSpeechPause(SpeechSynthesizer synthesizer) {
-
logDebug("朗读已暂停");
-
}
-
@Override
-
public void onSpeechFinish(SpeechSynthesizer synthesizer) {
-
logDebug("朗读已停止");
-
}
-
@Override
-
public void onNewDataArrive(SpeechSynthesizer synthesizer, byte[] dataBuffer, int dataLength) {
-
logDebug("新的音频数据：" + dataLength);
-
}
-
@Override
-
public void onError(SpeechSynthesizer synthesizer, SpeechError error) {
-
logError("发生错误：" + error.errorDescription + "(" + error.errorCode + ")");
-
}
-
@Override
-
public void onCancel(SpeechSynthesizer synthesizer) {
-
logDebug("已取消");
-
}
-
@Override
-
public void onBufferProgressChanged(SpeechSynthesizer synthesizer, int progress) {
-
-
}
-
-
}
