最近一直忙着写代码，每天的空闲时间不多。先占位，慢慢填坑。
讯飞开放平台：
http://www.xfyun.cn/
注册为开发者，然后参照文档一步步走下去。
由于是商业SDK，平台有诸多限制，免费的话只能联网，并且有限制次数，应用通过审核后无请求次数限制。
(补充：离线语音合成也可以免费，需要安装讯飞+应用。)
1.在线合成
写了一个Service，传入要说的话，然后就可以语音播报：
package com.tchip.carlauncher.service;

}
}

}3.1 最近一周天气JSON解析
String jsonString = result.getResultString();
if (!TextUtils.isEmpty(jsonString)) {
JSONObject jsonObject;
try {
jsonObject = new JSONObject(jsonString);
JSONArray mJSONArray = jsonObject.getJSONObject("data")
.getJSONArray("result");
for (int i = 0; i < 7; i++) {
JSONObject jsonDay = mJSONArray.getJSONObject(i);
String tempRange = jsonDay.getString("tempRange"); // 31℃~26℃
String tempArray[] = tempRange.split("~");
editor.putString("postTime",
jsonDay.getString("lastUpdateTime"));
editor.putString("day" + i + "air",
jsonDay.getString("airQuality"));
editor.putString("day" + i + "weather",
jsonDay.getString("weather"));
editor.putString("day" + i + "tmpHigh",
tempArray[0]);
editor.putString("day" + i + "tmpLow", tempArray[1]);
editor.putString(
"day" + i + "wind",
jsonDay.getString("wind")
+ jsonDay.getString("windLevel"));
editor.commit();
}3.2 语音交互
JSONObject jsonObject;
jsonObject = new JSONObject(text);
String strQuestion = jsonObject
.getString("text");
tvQuestion.setText(strQuestion);
String strService = jsonObject
.getString("service");
if ("openQA".equals(strService)
|| "datetime".equals(strService)
|| "chat".equals(strService)) {
String strAnswer = jsonObject
.getJSONObject("answer").getString(
"text");
tvAnswer.setText(strAnswer);
startSpeak(strAnswer);
} else if ("baike".equals(strService)) {
String strAnswer = jsonObject
.getJSONObject("answer").getString(
"text");
tvAnswer.setText(strAnswer);
} else if ("weather".equals(strService)) {
JSONArray mJSONArray = jsonObject
.getJSONObject("data")
.getJSONArray("result");
JSONObject todayJSON = mJSONArray
.getJSONObject(0);
String tempRange = todayJSON
.getString("tempRange");
String weather = todayJSON
.getString("weather");
String city = todayJSON.getString("city");
String strAnswer = city + "天气：" + weather
+ ",温度" + tempRange;
tvAnswer.setText(strAnswer);
