坑爹的语音合成,wp8只需要下载个语言包就可以实现中文的语音合成,但android只支持几种(英文、法语、德语等几种拉丁语系)。找了几个开源的合成引擎都不是很满意,退而求其次选择语音合成服务(讯飞),实现方式:
1、将SpeechApi.jar拷到工程的libs下,
2、
private static String TAG = "TTSTest";
private SpeechSynthesizer mTts;
private Toast mToast;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 初始化合成对象
mTts = new SpeechSynthesizer(this, mTtsInitListener);
mToast = Toast.makeText(this, "", Toast.LENGTH_LONG);
Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
String s = ((EditText) findViewById(R.id.editText1)).getText()
.toString();
@Override
public void onClick(View arg0) {
mTts.setParameter(SpeechConstant.ENGINE_TYPE, "cloud");
// mTts.setParameter(SpeechSynthesizer.VOICE_NAME, "vixk");
// mTts.setParameter(SpeechConstant.ENGINE_TYPE, "local");
mTts.setParameter(SpeechSynthesizer.VOICE_NAME, "xiaoyan");
mTts.setParameter(SpeechSynthesizer.SPEED, "50");
mTts.setParameter(SpeechSynthesizer.PITCH, "50");
int code = mTts.startSpeaking(s, mTtsListener);
if (code != 0) {
showTip("start speak error : " + code);
} else
showTip("start speak success.");
}
});
}
暂时选择这种办法把,但是这种有几个问题。一是语音要从服务器端传回的音频流,流量消耗比较大(wp8是本地合成),二是网络不好的情况下会比较慢。
