kandi X-RAY | htk Summary

htk is a HTML library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Pytorch, Tensorflow applications. htk has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

The Hidden Markov Model Toolkit (HTK) is a portable toolkit for building and manipulating hidden Markov models. HTK is primarily used for speech recognition research although it has been used for numerous other applications including research into speech synthesis, character recognition and DNA sequencing. HTK is in use at hundreds of sites worldwide. The HTK Book for HTK Version 3.5 has DNN-HMM Systems and the chapter 14 dedicated to Artificial Neural Networks. A DNN-HMM system A deep neural network (DNN) is a multi-layer perceptron (MLP) with many hidden layers. CUED-RNNLM toolkit present an implementation of recurrent neural network l anguage models (RNNLMs) training (on GPU), and efficient evaluation(on CPU).

QUESTION

HTK installing in windows10 / Not able to find VC98

Asked 2020-May-16 at 13:17

I am trying to install HTK Toolkit in my windows 10 machine.

It has a prerequisite of: Ensure that your PATH contains C:\Program Files\Microsoft Visual Studio\VC98\bin

I installed Microsoft Visual studios but I am not able to find the VC98 folder(file) in location where my visual studio is installed.

I tried to search it a lot of times, but still I was unsuccessful in finding it.

Can someone please solve this for me.

My final goal is to install HTK

Installing HTK on Microsoft Windows

Prerequisites

HTK has been verified to compile using Microsoft Visual Studio.

For testing, you will require a Perl interpreter such as ActivePerl.

You will need a tool such as 7-zip for unpacking the HTK source code archive.

It is helpful if you have some familiarity with using the DOS command line interface, as you will need to interact with it in order to compile, install and run HTK.

Ensure that your PATH contains C:\Program Files\Microsoft Visual Studio\VC98\bin Compilation

Unpack the HTK sources using 7-zip.

Open a DOS command window: Click Start, select Run type cmd at the prompt and click OK.

cd into the directory in which you unpacked the sources.

cd into the htk directory. Type:

cd htk

Create a directory for the library and tools. Type:

mkdir bin.win32

Run VCVARS32 (it should be in your path, see prerequisites above)

Build the HTK Library, which provides the common functionality used by the HTK Tools. Enter the following commands:

cd HTKLib

nmake /f htk_htklib_nt.mkf all

cd ..

Build the HTK Tools

cd HTKTools

nmake /f htk_htktools_nt.mkf all

cd ..

cd HLMLib

nmake /f htk_hlmlib_nt.mkf all

cd ..

cd HLMTools

nmake /f htk_hlmtools_nt.mkf all

cd ..

Installation

The HTK tools have now been built and are in the bin.win32 directory. You should add this directory to your PATH, so that you can run them easily from the command line in future.

Installing HTK:

I went through a very very tough time installing HTK on my computer.

This documentation will be helpful in installing it on any other computer.

Prequesities:

You should have a visual studio installed with c++ distribution. (Don’t just download MSVC). Download complete C++ distribution.

Download HTK Source code and HTK Samples.

Download and install Perl

Download any extracting software like( 7-zip)

Prior Steps:

Extract your HTK and HTK sample and keep it in two different directories. (Apart from each other)

Open VS and go on tool→ command line → any command prompt(I selected Developer command prompt)

Installing steps cd into the directory in which you unpacked the sources.(source code and not the sample) Execute the below commands one after the other.

cd htk

mkdir bin.win32

cd HTKLib

nmake /f htk_htklib_nt.mkf all

cd ..

Build the HTK Tools

cd HTKTools

nmake /f htk_htktools_nt.mkf all

cd ..

cd HLMLib

nmake /f htk_hlmlib_nt.mkf all

cd ..

cd HLMTools

nmake /f htk_hlmtools_nt.mkf all

cd ..

After this go to your bin.win32 folder and copy all the files to your

Sample directory inside HTKDemo.

cd into the directory HTKDemo and execute the command:

perl runDemo.pl configs/monPlainM1S1.dcf

Now you might find errors like hmm does not exist or such files does not exist when you execute this .

Just type mkdir (missing filename without parentheses)

And continue to do it until no errors are found

And soon you have reached the final stage : Success.

I know the documentation of current HTK is way too outdated and misleading but the stackoverflow community helped me to get through it. I am attaching some links that might be helpful:

QUESTION

Changing the layer mask of a pointer in MRTK v2.1

Asked 2020-Jan-17 at 02:58

I need to change the layer mask during runtime in order to select different objects depending on the context. From my understanding this should be done in the InputSystemProfile by editing the Pointers property:

CoreServices.InputSystem.InputSystemProfile.PointerProfile.PointingRaycastLayerMasks

But the field is read-only, and I can't find another way to edit it, other than manually in the editor. Btw I'm using an editable profile for the input system.

In HTK this was achieved by assigning a value to: GazeManager.Instance.RaycastLayerMasks

Any suggestions?

...

ANSWER

Answered 2020-Jan-16 at 10:00

you could change the pointers layer mask by overriding it All the pointers can by found here: CoreServices.InputSystem.DetectedInputSources and in each one you can do: ptr.PrioritizedLayerMasksOverride

Hope this helps

The -m32 is telling gcc to compile for a 32-bit platform. On a 64-bit machine, gcc normally only comes with 64-bit libraries. You have two options:

Install 32-bit headers and libraries. Here's how you'd do this on Ubuntu: https://askubuntu.com/questions/91909/trouble-compiling-a-32-bit-binary-on-a-64-bit-machine

Furthermore, why Do we have 3 states when is 5? Are 1 and 5 simply entry and exit points so they do not require a Mean and Variance?

Yes, boundary states are dummy.

For every "window", why do we have 26 coeffieincts instead of 25? What do they all represent? I believe:

MFCC type is MFCC_0_D as in Tutorial step 5, so those are 13 ceps and 13 deltas. You can also use HList -o -h to print the exact layout:
