C#调用SAPI实现语音合成的两种方法
我们都知道现在的语音合成TTS是可以通过微软的SAPI实现的，好处我就不多说了，方便而已，因为在微软的操作系统里面就自带了这个玩意，主要的方式有两种：
1、使用COM组件技术，不管是C++，C#,Delphi都能玩的转，开发出来的东西在XP和WIN7都能跑。（要引入SpeechLib，好像在项目上点引用，然后选到系统COM吧，好久没弄，记不清楚了）
2、使用WIN7的windows api，其实最终还是调用了SAPI，所以开发出来的东西就只能在WIN7上面跑。
其实不管是哪一种，都是调用SAPI，可能后一种代码比较简单，使用已经安装的TTS引擎，现在一般用NeoSpeech，这个就不解释了，太强大了这个发音。。。
COM组件技术：
public class Speach { private static Speach _Instance = null ; private SpeechLib.SpVoiceClass voice =null; //SAPI5.1private SpeechLib.SpVoice voice = null;//SAPI 5.4private Speach() { BuildSpeach() ; } public static Speach instance() { if (_Instance == null) _Instance = new Speach() ; return _Instance ; }private void SetChinaVoice() { voice.Voice = voice.GetVoices(string.Empty,string.Empty).Item(0) ; } private void SetEnglishVoice() { voice.Voice = voice.GetVoices(string.Empty,string.Empty).Item(1) ; } private void SpeakChina(string strSpeak) { SetChinaVoice() ; Speak(strSpeak) ; } private void SpeakEnglishi(string strSpeak) { SetEnglishVoice() ; Speak(strSpeak) ; } public void AnalyseSpeak(string strSpeak) { int iCbeg = 0 ; int iEbeg = 0 ; bool IsChina = true ; for(int i=0;i<strSpeak.Length;i++) { char chr = strSpeak[i] ; if (IsChina) { if (chr<=122&&chr>=65) { int iLen = i - iCbeg ; string strValue = strSpeak.Substring(iCbeg,iLen) ; SpeakChina(strValue) ; iEbeg = i ; IsChina = false ; } } else { if (chr>122||chr<65) { int iLen = i - iEbeg ; string strValue = strSpeak.Substring(iEbeg,iLen) ; this.SpeakEnglishi(strValue) ; iCbeg = i ; IsChina = true ; } } }//end for if (IsChina) { int iLen = strSpeak.Length - iCbeg ; string strValue = strSpeak.Substring(iCbeg,iLen) ; SpeakChina(strValue) ; } else { int iLen = strSpeak.Length - iEbeg ; string strValue = strSpeak.Substring(iEbeg,iLen) ; SpeakEnglishi(strValue) ; } } private void BuildSpeach() { if (voice == null) voice = new SpVoiceClass() ; }public int Volume { get { return voice.Volume ; } set { voice.SetVolume((ushort)(value)) ; } } public int Rate { get { return voice.Rate ; } set { voice.SetRate(value) ; } } private void Speak(string strSpeack) { try { voice.Speak(strSpeack,SpeechVoiceSpeakFlags.SVSFlagsAsync) ; } catch(Exception err) { throw(new Exception("发生一个错误："+err.Message)) ; } } public void Stop() { voice.Speak(string.Empty,SpeechLib.SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak) ; } public void Pause() { voice.Pause() ; } public void Continue() { voice.Resume() ; } }//end class private void Speak(string strSpeack) { try { voice.Speak(strSpeack,SpeechVoiceSpeakFlags.SVSFlagsAsync) ; } catch(Exception err) { throw(new Exception("发生一个错误："+err.Message)) ; }} using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Speech.Synthesis;using System.Speech;namespace StudyBeta{ public class SRead { public SpeechSynthesizer synth; //语音合成对象 public SRead() { synth = new SpeechSynthesizer(); } public SRead(int m, int n) { //使用 synth 设置朗读音量 [范围 0 ~ 100] synth.Volume = m; //使用 synth 设置朗读频率 [范围 -10 ~ 10] synth.Rate = n; } public void SpeakChina(string ggg) { //SpVoice Voice = new SpVoice(); synth.SelectVoice("Microsoft Lili"); //Voice.Speak(ggg, SpFlags); synth.SpeakAsync(ggg); //String speechPeople = synth.Voice; //使用 synth 设置朗读音量 [范围 0 ~ 100] // synth.Volume = 80; //使用 synth 设置朗读频率 [范围 -10 ~ 10] // synth.Rate = 0; //使用synth 合成 wav 音频文件: //synth.SetOutputToWaveFile(string path); } public void SpeakEnglish(string ggg) { //SpVoice Voice = new SpVoice(); synth.SelectVoice("VW Julie"); synth.Speak(ggg); //ggg为要合成的内容 } public int m { get { return synth.Volume; } set { synth.Volume = value; } } public int n { get { return synth.Rate; } set { synth.Rate = value; } }}
