I think I have tested with Marshal.AllocHGlobal, and got the same garbled output.
Currently it's done like this: m_spMemoryStream = new SpMemoryStream(); m_spMemoryStream.Format.Type = SpeechLib.SpeechAudioFormatType.SAFT8kHz16BitMono; m_spVoice.AudioOutputStream = m_spMemoryStream; m_spVoice.Speak(speechString, SpeechVoiceSpeakFlags.SVSFDefault | SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak ); byte [] byteArray = (byte[]) m_spMemoryStream.GetData(); GCHandle gcHandle = GCHandle.Alloc(byteArray, GCHandleType.Pinned); IntPtr bufferIntPtr = gcHandle.AddrOfPinnedObject(); SipxCallPlayBufferStart(m_handleIntPtr, bufferIntPtr, byteArray.Length, 0, false, false, true); ----- Original Message ----- From: "Daniel Sigurgeirsson" <[EMAIL PROTECTED]> To: "stipus" <[EMAIL PROTECTED]>; <[email protected]> Sent: Thursday, June 14, 2007 4:16 PM Subject: RE: [sipxtapi-dev] SipxCallPlayBufferStart and jerky output ...I'mpuzzled ! How is the buffer allocated in the first place? I've used the sipxCallPlayBufferStart (from .NET) with no problems, allocating buffer using Marshal.AllocHGlobal( ).
