speech enhancement

Speech Enhancement description
This software offers you the possibility of using a graphic equalizer for removing the stationary hindrances. Speech Enhancement represents a suite of applications that you may use when you want to imrpove the output of your microphone recording.

Single-microphone solution
This can be used for reduction of external hindrances and broadband color noises in speech signal. Controlled level of noises suppression in speech is up to 60 dB.

GritTecs Noise cancellation (NC) technology of single-microphone solution is used for reducing the external hindrances and background noises in speech signal. You can use this software for the selection of speech signal and for the selection of background noises.

Multi-microphone solution
Use this feature when noise from many different sources needs to be canceled. In its simplest form the technique uses two microphone solution.
Speaker is recorded synchronous with the source of hindrance (noise). The first microphone bases near by speaker, but the second one bases near by source of hindrance or noise.

Microphone Array solution
You can use this for reduction of external hindrances and ambient noises in speech source signal. In its simplest form the technique uses two array microphone configurations. By using acoustical beam-forming techniques, the microphone array can "focus" on the speakers position.

Speech Master is a powerful application for speech and sound processing and compression.

Speech Master is very useful tool for anyone who wants to organize their sound data in compressed archives.

The quality of the compressed speech is very high and the algorithms was specially developed for the high quality multimedia systems.

Here are some key features of "Speech Master":

· Recording and editing sound phonograms (mono, 11,22,44 kHz, 8 or 16 bits);
· Phonogram analyzing and enhancement (histogram view, compandering, filtering, etc.)
· Compressing speech and sound with several original compression algorithms:
- lossy speech compression more then 8,5 or 17 times for 11 kHz 8 or 16 bits phonograms;
- lossless sound compression for all frequencies 8 bits phonograms;
- lossy speech compression more then 8,8 or 17,6 times for 22 kHz 8 or 16 bits phonograms;
- storing all frequencies 8 or 16 bits phonograms without detected pauses.
· Automatic pause detection and restoration during playback that allows significantly increase the compression ratio.
· Storing compressed data in the form of the dictionaries.
· Any item in the dictionary has the accompanying text. This allows to search dictionaries for the specified text. Any item in the dictionary could be easy located and played back.
· Ability to work with very big phonograms by recording directly to hard disk.


Limitations:

· 20 test compressions

SCICA Speech is a free, useful and simple text-to-speech application which allows you to change the volume, rate, and voice of the speaker in addition to saving speech output to a wave file. It can also handle clipboard text as well.

Adaptive Contrast Enhancement is a GIMP plugin which can enhance the contrast of images.

The basic "Stretch Contrast" operation takes in the whole image at once, and if there is a white pixel anywhere in the image and a black pixel anywhere in the image, it figures the contrast is already as good as can be. But Adaptive Contrast Enhancement works to increase the contrast locally, and brings out details that most wide-sweeping contrast-enhancements pass over.

Whats New in This Release:

· This is just another development-libgimp-compatibility-thing.
· There is more interesting work going on for the upcoming 0.7, but its not quite ready yet.

Enhancement Pack for AppleWorks adds many new features to AppleWorks, accessible via new menu items, including new formula functions (eg Linear Regression, Frequency, Median); inter-database Lookup, Table of Contents, Text Along Arc, database batch field Replace, Compare word processing or database documents, Extract for XPress, and much more.

Immune System Enhancement description
Maintain a good health with Immune System Enhancement ebook. Immune System Enhancement application is a simple ebook that was designed to give you a full featured information about how to maintain a good health.

Body composition describes the percentages of fat, bone and muscle in your body.These percentages provide an overall view of your health and fitness in relation to your weight, health, and age. Weight and fat are often used together, but they are not interchangeable.

Organs involved in immunity include the thymus, bone marrow, spleen, tonsils and lymph nodes. Lymph circulates through lymphatic vessels in the body and also bathes the bodys cells. It is through the lymphatic system that fluid from the spaces between cells is drained, taking with it waste products, toxins and other debris from the tissues.

The application includes a free BMI Calculator.

The Java Binary Enhancement Tool (JBET) is a general Java program analysis and manipulation tool. Existing class files can be disassembled, reassembled, or edited programmatically through the JBET API. JBET can also be used to create new Java class files from scratch. JBET uses a convenient internal representation of all the contents of Java binary (.class) files, allowing the user to edit the classes easily, in a structured manner.

JBET was developed as part of the DARPA Self-Protecting Mobile Agents project under the OASIS and Active Networks programs (contract number N66001-00-C-8602) in order to study automated software obfuscation.

The Java language was chosen for this project because of the (relative) ease of constructing binary editing tools provided by the large amount of type information present in the class files. Our two reports, the Obfuscation Techniques Evaluation Report, and the Obfuscation Report, are available from the download area. The obfuscation tool developed is not part of this release.

JBET was also used in the DARPA/AFRL Survivable Server project (contract number F30602-00-C-0183) to add additional security checks to the Java Standard Library. (The Java SecurityManager API does not support many desirable security checks, such as continued authorization of file accesses after opening.)

JBET was used to replace the native method references in the Java standard library with stubs that call a pluggable security policy. This tool, called Jpolicy, is also available for download at this website. Jpolicy is very incomplete at this time, but may be interesting to those working in Java security or changing the standard library themselves.

The internal representation of Java class files used by JBET is intented to make it easy for programmers to write Java binary code transforms. Each element of Java class files has a corresponding internal data structure: ClassInfo for entire classes, MethodInfo for methods, FieldInfo for fields, Snippit for code blocks, and Instruction for individual instructions. Snippit and Instruction understand Java opcode syntax and semantics, allowing automated creation of valid Java programs. A Java-compatible class verifier is also included.

Some code transforms are difficult to program directly by manipulating Java instructions. For those transforms, a directed acyclic graph (DAG) representation of code is available. In the DAG representation, each basic block has a corresponding DAG, with a set of input and output nodes. Edges in the graph connect "producer" nodes (such as constants, or the result of calculations) to "user" nodes (such as method calls or other calculations). Methods are divided into basic blocks and control flow is stored at the basic block level (possible because Java has only fixed jump targets)

JBET requires a Java 1.4 virtual machine to run, although it can operate on class files from earlier Java versions. The packaging and build environment supplied supports Linux and Windows with Cygwin; however, the build process is simple and could be performed manually on other platforms. Perl is required for regression testing.

Jpolicy requires a Java 1.4 virtual machine to build, either Linux or Windows NT/XP with Cygwin. gcc is required for building on Windows (supplied with Cygwin). The runtime system can be either Java 1.3 or 1.4 (with Suns JVM only), running on Linux or Windows NT/XP. Windows 9x and Windows 2000 may work as well, but have not been tested.

Installation

1. Install jdk 1.4.1.
2. Set CLASSPATH to jdk1.4.1/jre/lib/rt.jar
3. cd src; make
4. If that didnt work, examine the makefile. java or javac may not be in the path.
5. To build a jar file that can be used with "java -jar jbet.jar", run "make jar".
6. If you have perl installed, run the tests with "make test".
Optionally, run "make regen; make test".

Make a symbolic link from jbet3/bin/jbet to somewhere in your path.

Usage

JBET uses the JNI format for class names, and JNI type and method descriptors. For a summary of this syntax, use jbet help syntax. Suns JVM specification may also be helpful.

To look at a class disassembly, use jbet print. Try disassembling a class you have source for, and was built with debug info (-g): jbet -P < classpath > print < classname >. Suns JVM specification has an instruction reference.

GNOME Speechs purpose is to provide a simple general API for producing text-to-speech output.

The GNOME Speech 1.0 API is currently under development, and it will provide API for both text-to-speech output as well as speech input. It will be heavily influenced by the Java Speech API, both the existing 1.0 specification, and the new 2.0 one which is currently under development.

GNOME Speech 0.4 is made up of three basic parts:

· IDL interface definitions
· libgnomespeech - Convenience library for speech driver development
· Java package to aid in developing GNOME Speech drivers in Java
· Sample driver implementations

Speech Recognition Plugin is a simple implementation of Speech Recognition & Speech Synthesis for REALbasic. It supports Speech Manager 1.5 or higher running on a PPC (including Mac OS X). It implements all feedback routines for cool user interaction.

Whats New in This Release:

· Added the property GetPhonemeOpcode() to get the phoneme about to be pronounced.
· Fixed a problem in which the plugin didnt work as expected under REALbasic 5.5 which could lead to a crash among other oddities.

Speech Recognition HOWTO is a project that contains instructions for using speech recognition software and hardware and their use on Linux systems.

Whats New in This Release:

· Changed license information (now GFDL) and added a new publication.

Speech Dispatchers project goal is to provide a device independent layer for speech synthesis through a simple, stable and well documented interface.

It takes care of most of the tasks necessary to solve in speech enabled applications. What is a very high level GUI library to graphics, Speech Dispatcher is to speech synthesis.

The application simply calls Speech Dispatcher interface functions and Speech Dispatcher handles its requests by sending them to particular synthesizer, handling priorities of the messages, keeping track of their history and providing some extra features like sound icons etc. The application neither needs to talk to synthesizers directly nor to fiddle with all the hard aspects of speech synthesis.

The architecture of Speech Dispatcher is based on a proven client/server model. The clients are all the applications in the system that want to speak. The basic means of client communication with Speech Dispatcher is through a TCP connection using the Speech Synthesis Independent Protocol (SSIP), however client libraries for various languages are also written as a part of the project, so usage is very straightforward. Currently we are working on C, Python, Elisp and Common Lisp library.

Speech Dispatcher is a control application, it doesnt perform the hard task of synthesizing the sound output itself. It can use any particular speech synthesizer (such as Festival, Flite, Epos etc.), through the concept of output modules – you can write an output module for any synthesizer you like.

Additionally, Speech Dispatcher can be configured to switch contexts on one synthesizer when used by multiple clients or to use different synthesizers for different clients (or different languages).

Whats New in This Release:

· This release adds support for eSpeak and IBM TTS.
· There are numerous bugfixes.
