Long story: On my new laptop, speech recognition is working well on the Windows=20 guest. I don't remember what client I was working with but I'm now usin= g=20 vmm-view in spice mode. I wasn't able to get the spice connection to=20 make the USB microphone interface visible in Windows but I was able to=20 get the built-in host to guest USB binding as supplied by the vmm mange= r. It's almost exactly right. What I'm noticing is that the audio stream i= s=20 not as clean as it could be. About every 15 to 20 seconds I hear a very= =20 quiet but distinct "thump". The reason this is a bad thing is because=20 the recognition engine thinks it's the start of an utterance, spins its= =20 wheels for about 10+ seconds trying to decode what it hears. When=20 NaturallySpeaking is spinning its wheels, it kills off all input becaus= e=20 it is trying to avoid a race condition between other inputs and itself. I'm not sure where the thump is coming from. I don't hear it on my othe= r=20 laptop and it's not external noise because it's extremely regular. I'm wondering if the same problem would occur over the spice USB=20 forwarding. I could use a bit of assistance figuring out what I'm doing= =20 wrong with spice USB forwarding so I can test out importing audio that = way. Thanks --- eric
