DotNetSpeech----文本轉wave語音文件

wav操作
引入dll(DotNetSpeech.dll)，引入以后需要選中項目中引入的dll，鼠標右鍵，選擇屬性，把“嵌入互操作類型”設置為False。不然會提示無法嵌入互操作類型"SpeechLib.SpVoiceClass".請改用適用的接口.
DotNetSpeech.SpeechAudioFormatType.SAFTCCITT_uLaw_11kHzMono表示音頻編碼格式為G711U

           var text = "我來測試一下！AB連續字母加空格";
            var path = Path.Combine(@"C:\ZZ_VoiceFile", $"1.wav");
            text = AddKongGeToPlateNo(text).Trim();
            SpVoiceUtil SpVoiceUtil = new SpVoiceUtil();
            SpVoiceUtil.setRate(0);
            SpVoiceUtil.setVolume(100);
            SpVoiceUtil.WreiteToWAV(path, text, DotNetSpeech.SpeechAudioFormatType.SAFTCCITT_uLaw_11kHzMono); //SAFT11kHz16BitMono 生成wav文件



       // 連續字母中加空格
        private static string AddKongGeToPlateNo(string s)
        {
            int length = s.Length;
            string[] letters = new string[] { "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z" };
            for (int i = 0; i < length - 1; i++)
            {
                string str = s.Substring(i, 1);
                string str1 = s.Substring(i + 1, 1);
                if (letters.Contains(str) && letters.Contains(str1))
                {
