用Java錄制語音

Question

我想用Java應用程序錄制語音; 我想這基本上是一個將在客戶端運行的applet。 但我不知道該怎么做......任何想法？ 另外，我想播放錄制的聲音。

我聽說過Java Speech API。 有什么想法可以提供幫助嗎？

我遲到了，但這里有關於捕獲音頻的官方文檔： http ： //docs.oracle.com/javase/tutorial/sound/capturing.html

（並直接從上面的鏈接復制這里是一些示例代碼:)

TargetDataLine line;
DataLine.Info info = new DataLine.Info(TargetDataLine.class,
                format); // format is an AudioFormat object
if (!AudioSystem.isLineSupported(info)) {
    // Handle the error ...

}
// Obtain and open the line.
try {
    line = (TargetDataLine) AudioSystem.getLine(info);
    line.open(format);
} catch (LineUnavailableException ex) {
    // Handle the error ...
}

// Assume that the TargetDataLine, line, has already
// been obtained and opened.
ByteArrayOutputStream out  = new ByteArrayOutputStream();
int numBytesRead;
byte[] data = new byte[line.getBufferSize() / 5];

// Begin audio capture.
line.start();

// Here, stopped is a global boolean set by another thread.
while (!stopped) {
    // Read the next chunk of data from the TargetDataLine.
    numBytesRead =  line.read(data, 0, data.length);
    // Save this chunk of data.
    out.write(data, 0, numBytesRead);
}
