Java 文本转语音 API

Question

我想在我的项目中实现文本到语音的实现，因为我使用了 java-google 文本到语音 api https://code.google.com/p/java-google-translate-text-to-speech/但最多只能识别 100 个字符。如果我给出超过 100 个字符的长段落，则会显示错误。

演讲还应保存为wav或mp3文件

java.io.FileNotFoundException: http://translate.google.com/translate_tts?q=Some%20JVMs%20put%20restrictions%20on%20the%20total%20amount%20of%20memory%20available%20on%20the%20heap%20If%20you%20are%20getting%20to.%20Some%20JVMs%20put%20restrictions%20on%20the%20total%20amount%20of%20memory%20available%20on%20the%20heap%20If%20you%20are%20getting%20to&tl=en

有什么方法可以更正此错误或建议我一个可以在 Java 中使用的良好的开源文本到语音 API。

你可以很容易地分割你的字符串，并像这样把字符串分成 block :

String longString;
...
Audio audio = Audio.getInstance();
InputStream sound; 

String[] chunks = longString.split(" ");
for(int i = 0; i < chunks.length; i++){
   sound = audio.getAudio(chunks[i], Language.ENGLISH);
   audio.play(sound);                              
}

现在，出于演示目的，我使用空格来拆分字符串。
