C# 導入speech lib，閱讀文本信息，support text to speech

1. 第一步，需要三個dll

using System.Speech.Synthesis;
using System.Speech.Recognition;
using SpeechLib;

SpeechLib的導入有點不太好找，參考下圖（圖片排版不太好）

 

 2.准備個測試demo

///獲取計算機本身自帶的語言系統

public static List<string> GetInstalledVoiceIdList()
        {
            List<string> resultList = new List<string>();
            try
            {
                SpVoice voice = new SpVoice();
                ISpeechObjectTokens ss = voice.GetVoices(string.Empty, string.Empty);
                if (ss != null && ss.Count > 0)
                {
                    for (int i = 0; i < ss.Count; i++)
                    {
                        resultList.Add(ss.Item(i).Id);
                    }
                }
            }
            catch (Exception)
            {
            }
            return resultList;
        }

//指定語言Speak方法中第二個參數，指定語言，從上段代碼中獲取到中文系統的index 是3，所以將傳遞3進行閱讀

voice.Speak(txt.Text, GetInstalledVoiceIdList()[3]);
