调用windows讲述人播放语音

1.[DllImport("winmm.dll", EntryPoint = "waveOutGetNumDevs")]

        public static extern int waveOutGetNumDevs();

2.using SpeechLib; 

        SpeechVoiceSpeakFlags svsf;
        SpVoiceClass svc = null;

3.右击Interop.SpeechLib ->嵌入式互操作类型，选择false

4.svc.Speak(content.Trim(), svsf);

完整代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SpeechLib;
using System.Runtime.InteropServices;
using System.Threading;

public class Speak
    {
        SpeechVoiceSpeakFlags svsf;
        SpVoiceClass svc = null;

        //增值为+10
        private Int16 _setVolume = 100;
        public Speak()
        {
            try
            {
                svsf = new SpeechVoiceSpeakFlags();
                svc = new SpVoiceClass();
                svc.SetVolume(Convert.ToUInt16(_setVolume));
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

        [DllImport("winmm.dll", EntryPoint = "waveOutGetNumDevs")]
        public static extern int waveOutGetNumDevs();

        public void Speak(string content)
        {
            try
            {
                if (string.IsNullOrEmpty(content.Trim()))
                {
                    return;
                }
                Thread.Sleep(100);
                svc.Speak(content.Trim(), svsf);
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
    }
