我正在开展一个需要文本到语音转换的项目。我下载了这个FreeTTS 1.2并熟悉了工作，我开始制作一个简单的拼写蜜蜂程序，其中的单词将由应用程序说出，你必须拼写正确。但是我面临的问题是语音是一样的，无论我做出什么改变。像最初我发现的代码在Voice（）构造函数
中有以下参数Voice kevin = new Voice("kevin",
Voice.GENDER_DONT_CARE, Voice.AGE_DONT_CARE, null);
然后我把它改成了
Voice kevin = new Voice("Different1",
Voice.GENDER_FEMALE, Voice.AGE_MIDDLE_ADULT, null);
但声音仍然相同。有一个speech.properties文件，它附带FreeTTS并运行我必须将该文件粘贴到我的主文件夹中的代码。我已经搜索了许多链接来解决这个问题，甚至检查了JSAPI和FreeTTS的Javadocs。我唯一的共同点是MBrola。我不是这样，但是当我运行代码时，控制台也会给出与之相关的消息。
System property "mbrola.base" is undefined. Will not use MBROLA voices.

答案 0 :(得分：1)
您可以访问的语音由VoiceManager类控制。它将通过几种不同的方法搜索系统中安装的语音包。默认情况下，您将安装3个声音：＆＃34; alan＆＃34;，＆＃34; kevin＆＃34;和＆＃34; kevin16＆＃34;。您需要先安装其他语音包（例如CMUArctic或MBROLA），然后才能使用3种默认语音以外的语音。
但是，一旦您安装了新语音（查看相应网站上的安装说明），您还需要将该语音目录添加到正确的位置，并将其名称添加到列出的文本文件中所有已安装的声音。查看安装语音包下的Programmer's Guide。作为参考，我最后将我的新语音包路径添加到我正在使用的freetts.jar旁边的voices.txt文件中（这有点特别 - 我忘了我已将它添加到我的Library / Java / Extensions文件夹中我的Mac，所以你可能要在那里添加voices.txt文件）。
您可以使用以下代码检查可用的语音：
VoiceManager voiceManager = VoiceManager.getInstance();
Voice[] voices = voiceManager.getVoices();
for (int i = 0; i < voices.length; i++){
System.out.print( "voice name is: " + voices[i].getName() +"\n");
}
为您已安装的语音成功添加语音目录后，您应该在运行该代码时看到它们已列出。
