Hello everyone,

I'm new to this forum and i'm sorry if a similar thread already exists, but I couldn't find one.
I'm trying to run the microsft speech SDK 5.1 sample code, but the Microsoft speech library seems to be missing from my computer. It's not in the COM tab when I click "Add reference" in the solution explorer (or in the menu for that matter).
I've been trying to download the library from somewhere all night, but this has been unsuccesful so far and i'm starting to get really frustrated.

I've installed Microsoft Speech SDK 5.1 and I have both runned and wrote my own applications in C# before without any problems.

If anyone knows how to add the microsoft speech library to my projects, I'd be forever gratetful! (Well, I'd be grateful).

Thanks in advance,

René

If the speech component never shows up in Visual Studio's COM list the usual causes are (a) the speech type library / COM DLL is not registered, or (b) a bitness mismatch between the registered COM component and the 32‑bit Visual Studio process. The following steps fix both cases in most setups.

Open an elevated command prompt (Run as administrator) and register the speech COM DLL. On 32‑bit Windows run:

regsvr32 %windir%\System32\sapi.dll

On 64‑bit Windows register the 32‑bit copy (Visual Studio is 32‑bit and needs the 32‑bit typelib):

C:\Windows\SysWOW64\regsvr32.exe C:\Windows\SysWOW64\sapi.dll

If you want, also register the 64‑bit copy with the System32 regsvr32. After registering, restart Visual Studio and look under Add Reference -> COM for the speech library (or use Add Reference -> Browse and point to the same DLL to force creation of the interop assembly).

If COM interop proves awkward, use the managed API included with the .NET runtime (System.Speech). Example usage:

using System.Speech.Synthesis;

var synth = new SpeechSynthesizer();
synth.Speak("Test");

Other troubleshooting tips: run the SDK/runtime installer again with Administrator rights and choose Repair, verify the DLL actually exists in the System32/SysWOW64 folder before running regsvr32, and make sure Visual Studio is closed while you register components. The bitness note from is important — register the DLL that matches the bitness of the process that will consume it.

I'm running Windows vista Ultimate, not sure what service pack as i'm at work right now, but I should think the latest.
