Unity 工具之 Azure 微软连续语音识别ASR的简单整理

一、简单介绍

二、实现原理

三、注意实现

四、实现步骤

五、关键脚本

一、简单介绍

Unity 工具类，自己整理的一些游戏开发可能用到的模块，单独独立使用，方便游戏开发。

本节介绍，这里在使用微软的Azure 进行语音合成的两个方法的做简单整理，这里简单说明，如果你有更好的方法，欢迎留言交流。

官网注册：

面向学生的 Azure - 免费帐户额度 | Microsoft Azure

官网技术文档网址：

技术文档 | Microsoft Learn

官网的TTS：

语音转文本快速入门 - 语音服务 - Azure AI services | Microsoft Learn

Azure Unity SDK 包官网：

安装语音 SDK - Azure Cognitive Services | Microsoft Learn

SDK具体链接：

https://aka.ms/csspeech/unitypackage

二、实现原理

1、官网申请得到语音识别对应的 SPEECH_KEY 和 SPEECH_REGION

2、因为语音识别需要用到麦克风，移动端需要申请麦克风权限

3、开启语音识别，监听语音识别对应事件，即可获取到识别结果

三、注意实现

1、注意如果有卡顿什么的，注意主子线程切换，可能可以适当解决你的卡顿现象

2、注意电脑端（例如windows）运行可以不申请麦克风权限，但是移动端（例如Android）运行要申请麦克风权限，不然无法开启识别成功，可能会报错：Exception with an error code: 0x15

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

System.ApplicationException: Exception with an error code: 0x15 at Microsoft.CognitiveServices.Speech.Internal.SpxExceptionThrower.ThrowIfFail (System.IntPtr hr) [0x00000] in <00000000000000000000000000000000>:0 at Microsoft.CognitiveServices.Speech.Recognizer.StartContinuousRecognition () [0x00000] in <00000000000000000000000000000000>:0 at Microsoft.CognitiveServices.Speech.Recognizer.DoAsyncRecognitionAction (System.Action recoImplAction) [0x00000] in <00000000000000000000000000000000>:0 at System.Threading.Tasks.Task.Execute () [0x00000] in <00000000000000000000000000000000>:0 at System.Threading.ExecutionContext.RunInternal (System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, System.Object state, System.Boolean preserveSyncCtx) [0x00000] in <00000000000000000000000000000000>:0 at System.Threading.Tasks.Task.ExecuteWithThreadLocal (System.Threading.Tasks.Task& currentTaskSlot) [0x00000] in

四、实现步骤

1、下载好SDK 导入

2、简单的搭建场景

3、编写对应脚本，测试语音识别功能

4、把测试脚本添加到场景中，并赋值

5、如果移动端，例如 Android 端，勾选如下，添加麦克风权限

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

5、运行，点击对应按钮，开始识别，Console 中可以看到识别结果

五、关键脚本

1、TestSpeechRecognitionHandler


using UnityEngine;
using UnityEngine.Android;
using UnityEngine.UI;public class TestSpeechRecognitionHandler : MonoBehaviour
{#region Data/// <summary>/// 按钮，文本/// </summary>public Button QuitButton;public Button ASRButton;public Button StopASRButton;public Text ASRText;/// <summary>/// m_SpeechAndKeywordRecognitionHandler/// </summary>SpeechRecognitionHandler m_SpeechAndKeywordRecognitionHandler;#endregion#region Liefecycle function/// <summary>/// Start/// </summary>void Start(){QuitButton.onClick.AddListener(OnClickQuitButton);ASRButton.onClick.AddListener(OnClickASRButton);StopASRButton.onClick.AddListener(OnClickStopASRButton);// 请求麦克风权限RequestMicrophonePermission();}/// <summary>/// 应用退出/// </summary>async void OnApplicationQuit() {await m_SpeechAndKeywordRecognitionHandler.StopContinuousRecognizer();}#endregion#region Private function/// <summary>/// RequestMicrophonePermission/// </summary>void RequestMicrophonePermission(){// 检查当前平台是否为 Androidif (Application.platform == RuntimePlatform.Android){// 检查是否已经授予麦克风权限if (!Permission.HasUserAuthorizedPermission(Permission.Microphone)){// 如果没有权限，请求用户授权Permission.RequestUserPermission(Permission.Microphone);}}else{// 在其他平台上，可以执行其他平台特定的逻辑Debug.LogWarning("Microphone permission is not needed on this platform.");}SpeechInitialized();}/// <summary>/// SpeechInitialized/// </summary>private void SpeechInitialized() {ASRText.text = "";m_SpeechAndKeywordRecognitionHandler = new SpeechRecognitionHandler();m_SpeechAndKeywordRecognitionHandler.onRecognizingAction = (str) => { Debug.Log("onRecognizingAction: " + str); };m_SpeechAndKeywordRecognitionHandler.onRecognizedSpeechAction = (str) => { Loom.QueueOnMainThread(() => ASRText.text += str);  Debug.Log("onRecognizedSpeechAction: " + str); };m_SpeechAndKeywordRecognitionHandler.onErrorAction = (str) => { Debug.Log("onErrorAction: " + str); };m_SpeechAndKeywordRecognitionHandler.Initialized();}/// <summary>/// OnClickQuitButton/// </summary>private void OnClickQuitButton() {

}

2、SpeechRecognitionHandler

using UnityEngine;
