i have met a very funny problem:
I am using SpeechLib com in c# to speak sth, I have tried a simple test
either speak english or speak chinese by clicking a button, e.g. below simple code:
the funny thing is: for speaking english, it is fine, no problem. but when speaking Chinese, it works for the first click then it does not work for the second click, but if I click more, sometime it works, but most time, it does not speak.
Anyone knows the problem?
thanks!

C#

private void btn_read_Click(object sender, EventArgs e)
        {
            //play english
            SpVoice voice = new SpVoice();
            voice.Voice=voice.GetVoices(string.Empty, string.Empty).Item(0);
            voice.Speak("hello", SpeechVoiceSpeakFlags.SVSFlagsAsync);

            //play chinese
            SpVoice voice = new SpVoice();
            voice.Voice=voice.GetVoices(string.Empty, string.Empty).Item(1);
            voice.Speak("你好", SpeechVoiceSpeakFlags.SVSFlagsAsync);
        }

If you just use the Chinese voice does it do the same thing?

as I said, for Chinese, sometimes it works, sometimes, it does not work.

What Wes means is: If you remove the English part completely and only leave the Chinese, does it still have the same problem?

Seraph_summer 20-Jul-12 3:08am

yes, the same problem.

can you please try also on your PC, the try is very simple,as you just need to add SpeechLib from com to your reference.
thanks!

more strange thing for me is:

people said the sapi.dll will appear in
C:\Program Files\Common Files\microsoft shared\Speech (I am using Vista)
but I can not find it here, only sapi.pdb and sapi.sym two files here
instead in another place I found sapi.dll
C:\windows\system32\Speech\common\

after downloading speach SDK5.1, I trying to run tutorials called "Coffee0", "coffee1" ..., it fails and the message is "SAPI fials to initialize ...".
no idea whether this is related to my problem.

Try it on a different PC - I'm wondering if your installation is corrupted somehow (MS tutorials usually work)

Seraph_summer 20-Jul-12 11:09am

thanks, yes, I can try on different PC, but I have only my own PC at home. even it works on other PC, e.g. my working PC, win7.
I need to make it work for Vista.
now I found more things strange to me:
I found that the SpeechLib on my PC is version 5.3. It seems does not support Chinese. then I try to download chinese package from Microsoft, but Only SpeechSDK51LangPack.exe exists, in order to install this, SpeechSDK51.exe has to be installed first. If I install SDK 5.1, then it seems this version too low and therefore can not replace original 5.3 version. then you can see the problems. I really do not understand why Microsoft does this way.

msttss22L.exe 2.0 MB

sapi.chm 2.3 MB

Sp5TTIntXP.exe 3.5 MB

SpeechSDK51.exe 68.0 MB

SpeechSDK51LangPack.exe 81.5 MB

SpeechSDK51MSM.exe 131.5 MB

Have you checked if you are getting anything?
Single step show ok?
