Unity之语音提问，语音答复

Unity之使用火山引擎实现音频剪辑提问，流式语音回复

示例

通过RecordVoice组件录制音频，

将录制音频作为参数传入VoiceQuestion组件中，播放音频

csharp 复制代码

using UnityEngine;

public class UseVoiceQuestion : MonoBehaviour
{
    [SerializeField] RecordVoice recordVoice;
    [SerializeField] VoiceQuestion voiceQuestion;

    KeyCode voiceInputKey = KeyCode.Space;
    bool enableVoiceInput = true;
    bool isRecordIng = false;

    void Awake()
    {
        recordVoice.OnRecordAudioCompleted += OnRecordVoiceCompleted;
        voiceQuestion.OnTextAnswerCompleted += OnTextAnswerCompleted;
        voiceQuestion.OnError += OnVoiceQuestionError;
    }

    void OnRecordVoiceCompleted(AudioClip audioClip)
    {
        voiceQuestion.InputQuestionAudio(audioClip);
    }

    void OnTextAnswerCompleted()
    {
        enableVoiceInput = true;
    }

    void OnVoiceQuestionError()
    {
        enableVoiceInput = true;
    }

    void Update()
    {
        if (enableVoiceInput == false) return;

        if (Input.GetKeyDown(voiceInputKey))
        {
            if (isRecordIng == false)
            {
                if (recordVoice.ExistMicrophoneDevice())
                {
                    Debug.Log("录音开始");
                    isRecordIng = true;
                    recordVoice.BeginRecord();
                }
                else
                {
                    Debug.LogError("没有录音设备，无法录音");
                }
            }
        }

        if (Input.GetKeyUp(voiceInputKey))
        {
            if (isRecordIng)
            {
                Debug.Log("录音结束");
                isRecordIng = false;
                enableVoiceInput = false;
                recordVoice.EndRecord();
            }
        }
    }

    void OnGUI()
    {
        GUI.skin.label.fontSize = 40;
        if (enableVoiceInput)
        {
            if (isRecordIng == false)
                GUILayout.Label("按下空格键，进行语音输入");
            else
                GUILayout.Label("语音录制中");
        }
        else
        {
            GUILayout.Label("等待提问结束");
        }
    }

    void OnDestroy()
    {
        voiceQuestion.OnError -= OnVoiceQuestionError;
        voiceQuestion.OnTextAnswerCompleted -= OnTextAnswerCompleted;
        recordVoice.OnRecordAudioCompleted -= OnRecordVoiceCompleted;
    }
}
