 attempts have been made by my partner and proved that these two approaches does not work. However, the results have given us sufficient information to come up with a new approach.
-This attempt is that inside the Host machine, we install the Streaming Host program and the Streaming Guest program. Namely, we cheated the Host machine as the ‘Virtual Machine’ and he found that in this case, the communication works perfectly. Then he created a real virtual machine and the test result is that the communication between the VM and the Host machine cannot be achieved.

 To summarize the results from these 2 attempts above, the communication between a VM and the Host machine can be achieved when the owner of the shared folder is the VM and amongst several VMs the communication can be achieved as well. So my idea is that how about we use a VM as the ‘bridge’ to link all the computers together instead of the Host machine.

 The outcome is that using this new arrangement, we are finally able to rebuild the system involving the host machine. After some basic function tests, we get a conclusion that this approach works perfectly. The advantage of this approach is that it can avoid the influence from the VM tools, which may be changed as the upgrade is made. However, the weakness of this arrangement is that the connection created is not stable enough and sometimes this weakness will cause a runtime error. More details about this error will be covered in the following section.

 For this project, with the aim of transcribing an incoming signal, the Multi-Profile Parallel Transcriber consists of two main components, namely a Streaming Host program and several Streaming Guest programs. The Streaming Host would reside on the operating system of the host computer, having control over multiple Streaming Guests as well as having access to a shared directory with a sub-directory for all Guest instances, which will store all vital information of the transcriptions. All Streaming Guests need to be integrated with an instance of DNS speech recognition engine but since DNS can only be instantiated once on a computer, each guest machine has to be run through a Virtual Machine (VM) in order to simultaneously run multiple guests, as shown in the following Figure. DNS is speaker-dependent speech transcriber, therefore the need to have a speech profile assigned for each guest instance plays a vital part for the project.

 The prototype gets the structure of an ASR by having the Streaming Host receive a digital audio input signal, the signal is then distributed to all Streaming Guest profiles. These Guest instances transcribe the signal against a speech profile, allocated by the Streaming Host, and return the transcribed information back to the Streaming Host with confidence scores for each utterance. The Host will then assemble the best confidence score as the best match for the speaker.

 As each speaker’s speech style is unique, the default Acoustic Model or Language Model is modified against the speaker’s speech style prior transcription to improve accuracy and performance. Modifying these models according to a user is known as training. Through training, a profile for the user will be created and this can be attained by having the speaker read a known passage of text or having to manually transcribe a voice recording of the speaker with a valid transcript for a few minutes.
