客户端调用Android端Java的代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class AndroidBtn : MonoBehaviour
{
    public GameObject prefab;
    public Transform content;
    //开始录音
    public void OnBtnOpen()
    {
        AndroidJavaClass aj = new AndroidJavaClass("com.unity3d.player.UnityPlayerActivity");
        aj.CallStatic("OnBtnOpen");
    }
    //结束录音
    public void OnBtnStop()
    {
        AndroidJavaClass aj = new AndroidJavaClass("com.unity3d.player.UnityPlayerActivity");
        aj.CallStatic("OnBtnStop");
    }
    //接收语音识别返回
    public void SetText(string str)
    {
        GameObject chat = Instantiate(prefab, content);
        chat.GetComponent<Text>().text = str;
    }
}

腾讯云开通账号

public static final String apppId = "xxx";
    public static final String secretId = "xxx";
    public static final String secretKey = "xxx";

Android端接入SDK代码

注意

<service android:name="com.tencent.cloud.qcloudasrsdk.onesentence.recorder.QCloudAudioMp3RecoderService" />

需要放在application标签内
初始化接口

private static QCloudOneSentenceRecognizer recognizer;
    // Setup activity layout
    @Override protected void onCreate(Bundle savedInstanceState)
    {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);

        String cmdLine = updateUnityCommandLineArguments(getIntent().getStringExtra("unity"));
        getIntent().putExtra("unity", cmdLine);

        mUnityPlayer = new UnityPlayer(this, this);
        setContentView(mUnityPlayer);
        mUnityPlayer.requestFocus();

        recognizer = new QCloudOneSentenceRecognizer(this, apppId, secretId, secretKey);
        recognizer.setCallback(this);

    }

开始录音

    public static void OnBtnOpen(){
        System.out.println("开始录音");
        try {
            /**
             * setDefaultParams 默认参数param
             * @param filterDirty    0 ：默认状态 不过滤脏话 1：过滤脏话
             * @param filterModal    0 ：默认状态 不过滤语气词  1：过滤部分语气词 2:严格过滤
             * @param filterPunc     0 ：默认状态 不过滤句末的句号 1：滤句末的句号
             * @param convertNumMode 1：默认状态 根据场景智能转换为阿拉伯数字；0：全部转为中文数字。
             * @param hotwordId  热词id，不使用则传null
             * @param engSerViceType  引擎模型类型，传null默认使用“16k_zh”
             */
            recognizer.setDefaultParams(0, 0, 1, 1,null,null);
            recognizer.getDefaultParams().setReinforceHotword(1); // 开启热词增强
            recognizer.recognizeWithRecorder();
            recognizer.setQCloudOneSentenceRecognizerAudioPathListener(new QCloudOneSentenceRecognizerAudioPathListener() {
                @Override
                public void callBackAudioPath(String audioPath) {
                    System.out.println("callBackAudioPath: audioPath="+audioPath);
                }
            });
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("exception msg" + e.getMessage());
        } finally {
        }
    }

结束录音

    public static void OnBtnStop(){
        System.out.println("结束录音");
        recognizer.stopRecognizeWithRecorder();
    }

回调继承

public class UnityPlayerActivity extends Activity implements IUnityPlayerLifecycleEvents, QCloudOneSentenceRecognizerListener

语音识别回调函数

@Override
    public void didStartRecord() {
        System.out.println("开始录音回调");
    }

    @Override
    public void didStopRecord() {
        System.out.println("结束录音回调");
    }

    @Override
    public void recognizeResult(QCloudOneSentenceRecognizer recognizer, String result, Exception exception) {
        if (exception != null) {
            System.out.println("语音识别错误：" + exception.getLocalizedMessage());
            UnityPlayer.UnitySendMessage("Button","SetText",exception.getLocalizedMessage());
        }
        else {
            System.out.println("语音识别成功：" + result);
//返回的是json文件，需要解析
            JsonParser parse = new JsonParser();
            JsonObject json = (JsonObject) parse.parse(result);
            JsonObject response = json.getAsJsonObject("Response");
            String str = response.get("Result").getAsString();
            UnityPlayer.UnitySendMessage("Button","SetText",str);
        }
    }
