使用 Java 录制语音

2022-09-03 15:42:52

我想使用Java应用程序录制语音;我想这基本上是一个将在客户端运行的小程序。但是我不知道该怎么做...任何想法?另外,我想播放录制的声音。

我听说过Java Speech API。任何想法,如果它可以帮忙?

我迟到了,但这里有关于捕获音频的官方文档:http://docs.oracle.com/javase/tutorial/sound/capturing.html

(直接从上面的链接复制过来的是一些示例代码来做到这一点:)

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);
}
