基于Android手机的语音数据采集系统（语音数据自动上传至电脑端）

一、服务器端程序设计-->server.py

python 复制代码

import socket
import os

SAVE_DIR = "voice_uploads"
if not os.path.exists(SAVE_DIR):
    os.makedirs(SAVE_DIR)

def start_server(host, port):
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    server_socket.bind((host, port))
    server_socket.listen(5)
    print(f"服务已启动：{host}:{port}")

    while True:
        client_socket, addr = server_socket.accept()
        print(f"\n手机连接：{addr}")
        try:
            name_len = int.from_bytes(client_socket.recv(2), 'big')
            file_name = client_socket.recv(name_len).decode('utf-8')
            file_size = int.from_bytes(client_socket.recv(4), 'big')
            save_path = os.path.join(SAVE_DIR, file_name)

            received = 0
            with open(save_path, 'wb') as f:
                while received < file_size:
                    buffer = client_socket.recv(min(4096, file_size - received))
                    if not buffer: break
                    f.write(buffer)
                    received += len(buffer)

            print(f"接收完成：{save_path}")
        except Exception as e:
            print(f"错误：{e}")
        finally:
            client_socket.close()

if __name__ == "__main__":
    start_server(host = "192.168.1.10", port=8092)

二、Android手机端程序设计

1、界面程序设计-->res/layout/activity_main.xml

2、Java程序设计-->java/com.example.voicecollection/MainActivity.java

java 复制代码

        });

        btnReset.setOnClickListener(v -> resetRecord());
        btnUpload.setOnClickListener(v -> uploadFile());
    }

    private void requestAudioPermission() {
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.RECORD_AUDIO}, REQUEST_AUDIO_PERMISSION);
        }
    }

    private void startRecord() {
        if (isRecording) return;

        releaseRecorder(); // 先彻底释放之前的录音器

        label = etLabel.getText().toString().trim();
        if (label.isEmpty()) {

    private void stopRecord() {

            return;
        }

        // 先停止，再释放，顺序绝对不能乱
        try {

        } catch (Exception ignored) {}

        releaseRecorder();
        btnRecord.setText("长按录音");
        tvStatus.setText("状态：录音完成，可上传或重录");
    }

    private void resetRecord() {
        releaseRecorder();
        if (currentFilePath != null) {
            new File(currentFilePath).delete();

            return;
        }
        SERVER_IP = etIP.getText().toString().trim();
        SERVER_PORT = safeParseInt(etPort.getText().toString());

        if (SERVER_IP.isEmpty() || SERVER_PORT <= 0) {
            tvStatus.setText("请填写正确的IP和端口");
            return;
        }

        new Thread(() -> {
            try {
                runOnUiThread(() -> tvStatus.setText("状态：上传中..."));
                Socket socket = new Socket(SERVER_IP, SERVER_PORT);

                socket.getOutputStream().write(new byte[]{(byte) (name.length() >> 8), (byte) name.length()});
                socket.getOutputStream().write(name.getBytes());
                socket.getOutputStream().write(new byte[]{(byte) (size >> 24), (byte) (size >> 16), (byte) (size >> 8), (byte) size});

                FileInputStream fis = new FileInputStream(file);
                byte[] buffer = new byte[4096];
                int len;
                while ((len = fis.read(buffer)) != -1) {
                    socket.getOutputStream().write(buffer, 0, len);
                }
                fis.close();
                socket.close();

            }
        }).start();
    }

                mediaRecorder.release();
            } catch (Exception ignored) {}

    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        releaseRecorder();
    }

    private int safeParseInt(String str) {
        try {
            return Integer.parseInt(str.trim());
        } catch (NumberFormatException e) {
            return 0;
        }
    }
}

3、权限设置-->AndroidManifest.xml

java 复制代码

    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.INTERNET" />

4、编译生成APK文件，在手机端安装

三、测试

1、运行server.py启动服务器

2、打开手机APP采集音频数据
