网友: 技术文档 2025-07-30 11:09:45

一、讯飞开放平台账号注册

  1. 访问讯飞开放平台官网： https://www.xfyun.cn/

  2. 点击右上角的\"注册/登录\"按钮

  3. 完成账号注册并登录

  4. 在控制台创建应用：讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音

    • 进入\"控制台\">“我的应用”
    • 点击\"创建新应用\"
    • 填写应用名称和应用描述
    • 提交创建

  5. 获取应用ID和密钥：
    讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音

    • 在应用详情页面可以看到APPID
    • 记录下APPID、APIKey和APISecret，这些将在代码中使用（离线语音唤醒只使用了APPID ）

二、SDK下载与配置

  1. 在讯飞开放平台下载WIn SDK：

    • 进入\"语音识别\">“语音唤醒”讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音

    • 选择\"唤醒词设置\">“前往SDK下载中心”讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音

    • 点击\"回到旧版\">

    • 选择\"选择应用（自己设置的应用名称）\">“选择平台 Windows”>“选择AI能力 语音唤醒”

    • 点击SDK下载
      讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音

  • 解压结构讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音
    讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音sdk包的说明

  1. 在Unity项目中配置SDK：

    • 创建新的Unity项目或打开现有项目

    • 找到bin文件下的资源讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音

    • 将下载的SDK解压，将其中的库文件复制到项目的Plugins文件夹中

    • 将唤醒资源文件(wakeupresource.jet)放入StreamingAssets文件夹

    • 在Unity中的结构讯飞离线语音包在Unity中的应用详解PC篇_unity讯飞离线语音

  2. 安装NAudio库：

    • 通过NuGet包管理器安装NAudio
    • 或者手动下载NAudio.dll并添加到项目引用中
    • NAudio是一个开源的.NET音频处理库，在您的讯飞语音唤醒项目中主要用于以下功能：
    • 音频录制 ：通过 WaveInEvent 类捕获麦克风输入的音频数据，这在您的代码中用于持续监听用户的语音输入。
    • 音频格式处理 ：使用 WaveFormat 类设置音频的采样率(16000Hz)、位深度(16位)和通道数(单通道)，确保录制的音频符合讯飞SDK的要求。
    • 音频数据回调 ：通过 DataAvailable 事件获取实时的音频数据，在您的代码中通过 RecordingStart 方法处理这些数据。
    • 音频设备管理 ：提供对录音设备的控制，包括启动录音( StartRecording )和停止录音( StopRecording )。

三、代码实现

1. 创建唤醒功能实现类

首先，我们需要创建一个Wakeup类来实现语音唤醒功能。这个类将负责：

  • 讯飞SDK的初始化和登录
  • 音频录制和处理
  • 唤醒检测逻辑
  • 唤醒词识别和解析
  • UI显示和交互
public class Wakeup : MonoBehaviour{ // 讯飞SDK账号信息配置 只用id //private const string user = \"\";//账号 // private const string pwd = \"\";//密码 private const string app_id = \"appid=自己的id,word_dir= . \";//appid aiui.dll和msc.dll要用到}

2. 创建线程分发器

为了在子线程中处理唤醒检测，同时能够在主线程更新UI，我们需要创建一个线程分发器：

using System;using System.Collections;using System.Collections.Generic;using System.Threading;using UnityEngine;/// /// 线程分发器，用于在主线程中执行来自其他线程的操作/// public class UnityMainThreadDispatcher : MonoBehaviour{ private static readonly Queue<Action> _executionQueue = new Queue<Action>(); private static UnityMainThreadDispatcher _instance; public static UnityMainThreadDispatcher Instance { get { if (_instance == null) { _instance = FindObjectOfType<UnityMainThreadDispatcher>(); if (_instance == null) {  GameObject go = new GameObject(\"UnityMainThreadDispatcher\");  _instance = go.AddComponent<UnityMainThreadDispatcher>();  DontDestroyOnLoad(go); } } return _instance; } } private void Awake() { if (_instance == null) { _instance = this; DontDestroyOnLoad(gameObject); } else if (_instance != this) { Destroy(gameObject); } } private void Update() { lock (_executionQueue) { while (_executionQueue.Count > 0) { _executionQueue.Dequeue().Invoke(); } } } ///  /// 在主线程中执行操作 ///  /// 要执行的操作 public static void RunOnMainThread(Action action) { if (Thread.CurrentThread.ManagedThreadId == 1) { action(); } else { lock (_executionQueue) { _executionQueue.Enqueue(action); } } }}

3. 讯飞语音识别sdk的封装

四、唤醒功能实现流程

1. 初始化与登录

首先，我们需要在Start方法中初始化讯飞SDK并登录：

private void Start(){ // 登录讯飞SDK MSPLogin(user, pwd, app_id); // 初始化录音设备 waveIn = new WaveInEvent(); waveIn.WaveFormat = new WaveFormat(sampleRate, bitsPerSample, channels); waveIn.DataAvailable += RecordingStart; // 注册录音数据可用事件 waveIn.RecordingStopped += RecordingStopped; // 注册录音停止事件 waveIn.StartRecording(); // 开始录音 // 创建并启动唤醒检测线程 thread = new Thread(() => { while (true) { MSC_Awaken(); // 持续进行唤醒检测 } }); thread.IsBackground = true; // 设置为后台线程 thread.Start(); // 启动线程}

2. 音频录制与处理

使用NAudio库进行音频录制，并在回调中处理音频数据：

private void RecordingStart(object sender, WaveInEventArgs e){ int start = e.BytesRecorded; // 获取开始位置 根据数据长度定义 int length = audio_byte.Length - e.BytesRecorded; // 获取长度 byte[] destination = new byte[length]; // 将旧数据向前移动，为新数据腾出空间 Array.Copy(audio_byte, start, destination, 0, length); audio_byte = destination.Concat(e.Buffer).ToArray(); // 合并新旧数据}

3. 唤醒检测

在单独的线程中持续进行唤醒检测：

private void MSC_Awaken(){ // 开始唤醒会话 session_id = MSCDLL.QIVWSessionBegin(null, qivw_session_begin_params, ref error_code); if (error_code != (int)Errors.MSP_SUCCESS) { Debug.LogError(\"初始化唤醒会话失败，错误信息：\" + error_code); return; } // 注册唤醒回调函数 message = MSCDLL.QIVWRegisterNotify(session_id, cb_ivw_msg_proc, IntPtr.Zero); // ... 写入音频数据和结束会话 ...}

4. 唤醒回调处理

当检测到唤醒词时，通过回调函数处理唤醒事件：

private void MSC_Awaken(){ // 开始唤醒会话 session_id = MSCDLL.QIVWSessionBegin(null, qivw_session_begin_params, ref error_code); if (error_code != (int)Errors.MSP_SUCCESS) { Debug.LogError(\"初始化唤醒会话失败，错误信息：\" + error_code); return; } // 注册唤醒回调函数 message = MSCDLL.QIVWRegisterNotify(session_id, cb_ivw_msg_proc, IntPtr.Zero); // ... 写入音频数据和结束会话 ...}

五、自定义唤醒词配置

讯飞离线唤醒支持自定义唤醒词，需要在讯飞开放平台上进行配置：

  1. 登录讯飞开放平台
  2. 进入\"控制台\">“我的应用”>“应用详情”
  3. 选择\"语音唤醒\"服务
  4. 在\"唤醒词管理\"中添加自定义唤醒词
  5. 训练唤醒词模型
  6. 下载更新后的唤醒资源文件(wakeupresource.jet)
  7. 替换项目中的唤醒资源文件
    在代码中，我们通过字典映射唤醒词ID和名称：
private Dictionary<int, string> wakeupWordDict = new Dictionary<int, string>(){ { 0, \"你好啊\" }, { 1, \"小爱同学\" }, { 2, \"你好小飞\" }, { 3, \"暂停对话\" } // 根据实际情况添加更多唤醒词};

六、交互逻辑实现

当检测到唤醒词后，我们可以根据不同的唤醒词执行不同的操作：

// 根据唤醒词ID执行不同操作switch (wakeupId){ case 0: Debug.Log(\"触发了第一个唤醒词: \" + wakeupWord); // 第一个唤醒词的特定操作 break; case 1: Debug.Log(\"触发了第二个唤醒词: \" + wakeupWord); // 第二个唤醒词的特定操作 break; // ... 其他唤醒词处理 ...}

同时，我们可以通过UI文本显示唤醒状态：

```csharp// 在主线程中更新UI文本UnityMainThreadDispatcher.RunOnMainThread(() => { if (text != null) { text.text = $\"唤醒成功: {wakeupWord} (ID:{wakeupId})\"; // 使用协程在一段时间后清空文本，为下次唤醒做准备 StartCoroutine(ClearTextAfterDelay(2.0f)); }});

七、资源清理

在组件销毁时，需要正确清理资源：```

```csharpprivate void OnDestroy(){ waveIn?.StopRecording(); // 停止录音 waveIn?.Dispose(); // 释放录音资源 thread?.Abort(); // 终止线程 MSPLoginOut(); // 注销讯飞SDK}

八、常见问题与解决方案

  1. 唤醒不灵敏或误唤醒

    • 调整唤醒阈值参数(ivw_threshold)
    • 在安静环境下重新训练唤醒词
    • 使用更高质量的麦克风

  2. SDK初始化失败

    • 检查APPID是否正确
    • 确认网络连接是否正常
    • 查看讯飞开放平台应用是否已审核通过

  3. 音频数据处理问题

    • 确保音频格式与SDK要求一致(16K采样率、16位深度、单通道)
    • 检查音频数据缓冲区大小是否合适

  4. 线程安全问题

    • 使用UnityMainThreadDispatcher确保UI更新在主线程进行
    • 避免在多个线程中同时访问共享资源
