语音播报（播报本地音频文件）实现收款金额的播报

最近项目需要实现语音播报收款金额，本来要使用百度AL开发平台的语音合成进行语音播报，虽然这个是可以完美实现，但是这个在免费的情况下有这播放条数的限制，所以最终决定使用播放本地语音的方式进行实现。不多说，直接贴代码，代码也都进行了注释：

一、FileUtils文件读取工具类

public class FileUtils {public static AssetFileDescriptor getAssetFileDescription(String filename) throws IOException {AssetManager manager = CardDoctorApplication.getContext().getAssets();return manager.openFd(filename);}
}

CardDoctorApplication是自己的application类，就不贴出来了。

二、音频播放类

import android.content.res.AssetFileDescriptor;
import android.media.MediaPlayer;import java.io.IOException;
import java.util.List;
import java.util.concurrent.CountDownLatch;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;/*** 音频播放类* Created by Administrator on 2018/10/9.*/public class VoiceSpeaker {private static VoiceSpeaker sInstance;private ExecutorService service;//线程池private VoiceSpeaker() {service = Executors.newCachedThreadPool();}/*** 获取音频播放对象* @return*/public static synchronized VoiceSpeaker getInstance() {if (sInstance == null) {sInstance = new VoiceSpeaker();}return sInstance;}/*** 播放前检查* @param list*/public void speak(final List<String> list){if (service != null){service.execute(new Runnable() {@Overridepublic void run() {start(list);}});}}/*** 开始播放* @param list*/private void start(final List<String> list) {synchronized (this) {final CountDownLatch latch = new CountDownLatch(1);//并发MediaPlayer player = new MediaPlayer();/*** 遍历音频模板集合，按顺序播放音频文件*/if (list != null && list.size() > 0) {final int[] counter = {0};/*** format方法使用占位符进行格式化* %s中的 s 代表 字符串类型** path是音频文件的路径，通过格式化之后匹配到对应的音频文件*/String path = String.format("sound/tts_%s.mp3", list.get(counter[0]));AssetFileDescriptor fd = null;try {fd = FileUtils.getAssetFileDescription(path);/*** 设置要使用的数据源（FileDescriptor）。FileDescriptor必须是可搜索的（注意，LocalSocket不可搜索）。调用者有责任关闭文件描述符。* 参数说明：* 第一个参数：FileDescriptor：您要播放的文件的FileDescriptor* 第二个参数：long：要播放的数据开始的文件的偏移量，以字节为单位* 第三个参数：long：要播放的数据的字节长度*/player.setDataSource(fd.getFileDescriptor(), fd.getStartOffset(),fd.getLength());/*** 准备播放器以异步方式播放。设置数据源和显示表面后，您需要调用prepare（）或prepareAsync（）。* 对于流，您应该调用prepareAsync（），它会立即返回，而不是阻塞，直到缓冲了足够的数据。*/player.prepareAsync();/*** 注册媒体源准备播放时要调用的回调。*/player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {@Overridepublic void onPrepared(MediaPlayer mp) {mp.start();}});/*** 注册在回放期间到达媒体源末尾时要调用的回调。*/player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {@Overridepublic void onCompletion(MediaPlayer mp) {/*** 将MediaPlayer重置为未初始化状态。调用此方法后，您必须通过设置数据源并调用prepare（）再次初始化它。*/mp.reset();counter[0]++;if (counter[0] < list.size()) {try {AssetFileDescriptor fileDescriptor = FileUtils.getAssetFileDescription(String.format("sound/tts_%s.mp3", list.get(counter[0])));mp.setDataSource(fileDescriptor.getFileDescriptor(), fileDescriptor.getStartOffset(), fileDescriptor.getLength());mp.prepare();} catch (IOException e) {e.printStackTrace();latch.countDown();//完成预期工作，发出完成信号...}} else {/*** 是否MediaPlayer资源*/mp.release();latch.countDown();//完成预期工作，发出完成信号...}}});} catch (IOException e) {e.printStackTrace();latch.countDown();//完成预期工作，发出完成信号...}finally {if (fd != null){try {fd.close();//关闭文件操作} catch (IOException e) {e.printStackTrace();}}}}try {latch.await();等待主线程执行完毕，获得开始执行信号...this.notifyAll();} catch (InterruptedException e) {e.printStackTrace();}}}
}

三、音频播放模板处理类

import android.text.TextUtils;import com.yunkahui.datacubeper.common.utils.LogUtils;import java.util.ArrayList;
import java.util.List;/*** 音频播放模板处理类* Created by Administrator on 2018/10/9.*/public class VoiceTemplate {private static final String DOT = ".";private String numString;private String prefix;//收款成功音频private String suffix;//元的音频public VoiceTemplate() {}/*** 获取播放的音频文件顺序集合** @param money* @return*/public static List<String> getDefaultTemplate(String money) {return new VoiceTemplate().prefix("success").numString(money).suffix("yuan").gen();}public String getPrefix() {return prefix;}public VoiceTemplate prefix(String prefix) {this.prefix = prefix;return this;}public String getSuffix() {return suffix;}public VoiceTemplate suffix(String suffix) {this.suffix = suffix;return this;}public String getNumString() {return numString;}public VoiceTemplate numString(String numString) {this.numString = numString;return this;}public List<String> gen() {return genVoiceList();}private List<String> createReadableNumList(String numString) {List<String> result = new ArrayList<>();if (!TextUtils.isEmpty(numString)) {int len = numString.length();for (int i = 0; i < len; i++) {if ('.' == numString.charAt(i)) {result.add("dot");} else {result.add(String.valueOf(numString.charAt(i)));}}}return result;}/*** 播放音频文件顺序** @return*/private List<String> genVoiceList() {List<String> result = new ArrayList<>();if (!TextUtils.isEmpty(prefix)) {result.add(prefix);}if (!TextUtils.isEmpty(numString)) {result.addAll(genReadableMoney(numString));}if (!TextUtils.isEmpty(suffix)) {result.add(suffix);}return result;}/*** 拆分金额成一个集合，以对应音频文件** @param numString* @return*/private List<String> genReadableMoney(String numString) {List<String> result = new ArrayList<>();if (!TextUtils.isEmpty(numString)) {/*** contains（）返回TRUE时，该字符串中存在该字符* 此处判断字符串是否包含小数点*/if (numString.contains(DOT)) {String integerPart = numString.split("\\.")[0];String decimalPart = numString.split("\\.")[1];//整数部分List<String> intList = readIntPart(integerPart);//小数点之后的部分List<String> decimalList = readDecimalPart(decimalPart);result.addAll(intList);if (!decimalList.isEmpty()) {result.add("dot");result.addAll(decimalList);}} else {//intresult.addAll(readIntPart(numString));}}return result;}/*** 拆分小数点后面字符串** @param decimalPart* @return*/private List<String> readDecimalPart(String decimalPart) {List<String> result = new ArrayList<>();if (!"00".equals(decimalPart)) {char[] chars = decimalPart.toCharArray();for (char ch : chars) {result.add(String.valueOf(ch));}}return result;}/*** 当金额为整数时，直接拆分，拆分成** @param integerPart* @return*/private List<String> readIntPart(String integerPart) {List<String> result = new ArrayList<>();String intString = readLong(Long.parseLong(integerPart));int len = intString.length();for (int i = 0; i < len; i++) {char current = intString.charAt(i);if (current == '拾') {result.add("ten");} else if (current == '佰') {result.add("hundred");} else if (current == '仟') {result.add("thousand");} else if (current == '万') {result.add("ten_thousand");} else if (current == '亿') {result.add("ten_million");} else {result.add(String.valueOf(current));}}return result;}private static final char[] NUM = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};private static final char[] CHINESE_UNIT = {'元', '拾', '佰', '仟', '万', '拾', '佰', '仟', '亿', '拾', '佰', '仟'};/*** 返回关于钱的中文式大写数字,支仅持到亿,超过亿则需要使用长整型long*/public static String readLong(long moneyNum) {long mMoneyNum = moneyNum;String res = "";int i = 0;if (moneyNum == 0) {return "0";}if (moneyNum == 10) {return "拾";}if (moneyNum > 10 && moneyNum < 20) {return "拾" + moneyNum % 10;}while (moneyNum > 0) {res = CHINESE_UNIT[i++] + res;res = NUM[(int) (moneyNum % 10)] + res;moneyNum /= 10;}/*** replaceAll() 方法使用给定的参数 replacement 替换字符串所有匹配给定的正则表达式的子字符串。* 参数* 第一个参数：regex -- 匹配此字符串的正则表达式。* 第二个参数：newChar -- 用来替换每个匹配项的字符串。* 成功则返回替换的字符串，失败则返回原始字符串。*/if (mMoneyNum >= 100000000) {//整亿if (mMoneyNum % 100000000 == 0) {return res.replaceAll("0[拾佰仟万]", "0").replaceAll("0+亿", "亿").replaceAll("0+万", "万").replaceAll("0+元", "元").replaceAll("0+", "0").replace("元", "");} else {//非整亿，有万位或者千位（这里万位包括万、十万、百万、千万位）String a = String.valueOf(mMoneyNum);LogUtils.e("原始数据--》" + a);LogUtils.e("截取万位--》" + a.substring(a.length() - 8, a.length() - 4));if (Long.parseLong(String.valueOf(mMoneyNum).substring(String.valueOf(mMoneyNum).length() - 8, String.valueOf(mMoneyNum).length() - 4)) == 0) {//万位为全部为0的情况，例如 1500002000.00 此情况不需要读出 万，直接读一十五亿零二千元return res.replaceAll("0[拾佰仟]", "0").replaceAll("0+亿", "亿").replaceAll("0+万", "0").replaceAll("0+元", "元").replaceAll("0+", "0").replace("元", "");} else {//万位为不为0的情况，例如  1520002000.00 此情况需要读出 万，读一十五亿二千万二千元return res.replaceAll("0[拾佰仟]", "0").replaceAll("0+亿", "亿").replaceAll("0+万", "万").replaceAll("0+元", "元").replaceAll("0+", "0").replace("元", "");}}} else {//小于一亿return res.replaceAll("0[拾佰仟]", "0").replaceAll("0+亿", "亿").replaceAll("0+万", "万").replaceAll("0+元", "元").replaceAll("0+", "0").replace("元", "");}}}

四、新建assets文件夹，把音频文件放在assets目录下

此demo可支持到千亿播放，对播放的语序也进行了一些处理，但是可能还有些许情况没有考虑到，需要使用的朋友可以按自己的需求自行添加

新添加内容：

最近接到反馈，说语音播报的速度太慢，跟一个老大爷一样，所以在处方面做了优化。此处没有使用Android自带的播放器，而是使用Google支持的第三方的播放器ExoPlayer ，需要了解ExoPlayer 可到这个网址了解，https://google.github.io/ExoPlayer/

ExoPlayer gitgub地址https://github.com/google/ExoPlayer

下面直接贴出代码，新的代码只是一个方法，替换之前的播报方法即可，或者根据需求使用两者中的其中一个即可。

github 项目https://github.com/freakcsh/VoiceDemo.git 此项目还接入了百度语音的demo，还有极光推送，但是极光被我干掉了，使用不了。
