@hackage mmsyn7ukr0.7.6.0

A program and a library that can be used as a simple basic interface to some SoX functionality or for producing the approximately Ukrainian speech with your own recorded voice (actually it produces the needed sound representations).

The program starts with Caution to be responsible for usage and to use it personally. Then the program guides you through the creating and using your Ukrainian "voice". Please, use it carefully. After the execution you can execute mmsyn7h program to produce some records with your newly created "voice". During the execution of the last one you can choose whether to remove (clean) all the created sound files in the current directory for security reasons. If the programs terminate by interruption (or generally) it is a good practice to remove the current directory sound files manually.

    ***** CAUTION! *****

"The possession of great power necessarily implies great responsibility."

                                      (William Lamb)

The program mmsyn7ukr produces the "voice" represented as an ordered set of sounds each of which corresponds (represents) one of the Ukrainian sounds so that using them together by mmsyn7h program (https://hackage.haskell.org/package/mmsyn7h) can be a background for sound synthesis. If you pronounce sounds as the appropriate Ukrainian ones, close to proper Ukrainian speech with your own voice. This program approximates your voice with a sequence of recorded separate sounds with your control over the duration of the sounds. They are then precessed by the SoX binaries already installed in the system to produce the needed sounds and then you can pronounce some Ukrainian text with your recorded "voice" using mmsyn7h program. In-between you can do some additional processing as you need. Moreover, you can substitute whatever sounds you like (consider being sensible) instead of your own voice.

Be aware that if somebody can get access to the sounds of your voice or to the recorded speech (except you) then this possibility itself creates security issues and concerns. So, please, do NOT give access to such records to anybody else except you.

In such a case, the program is for personal usage of every user ONLY!

Being given as an advice in such a case, run the program in the empty directory with the current user permissions to write, read and search and provide some proofs and evidence that nobody else can even read the files in the directory. May be, it is better to execute the program being in the directory located in the RAM, then consequently wait until the program ends and then reboot the computer.

If the program ends earlier, you must then remove (better wipe) the directory contents. No other users should have access to the computer after you have begun to run the program and have not deleted (or better wiped) the contents of the directory. Please, be aware, that there are possibilities to read sensitive information from the drives after you have deleted the files in a usual way. You can use wiping for better security. Besides, if somebody can get access to the memory of the computer or to the directory contents where you run the program or (may be) to the temporary files created by SoX or to the drive where you run the program (not in the RAM, or may be in it) then your voice can be stolen and / or used inappropriately. Use all possible precautions and measures to avoid the situation.

Be aware also that the given by the program technology (or documentation for it in any form) of the voice processing can be improved so there is NO guarantees that the given technology or its successors cannot be used in violating your voice identity to produce from some available voice records the voice for the inappropriate usage. Therefore, better is to prove your identity not only with the solely voice itself but with some additional independent sources and measures.

The author of the program accordingly to the LICENSE (MIT) does not response for any possible issues, but by this notification tries to intent you to be aware of some possible issues.

    ***** Command Line Arguments *****

If you specify as a first command line argument one of the numbers below the program behaves as follows: -1 -> the program does not reduce noise, it only resamples the audio to the needed 22050 Hz and adjusts the amplitude; 0 -> after the noise reduction the program only resample the audio to the needed 22050 Hz and adjusts the amlitude; 1 -> after the noise reduction the program additionally to the 0-processing truncates the silence from the beginning and end of the audio to the level given by the second command line parameter; 2 -> after the noise reduction the program additionally to the 1-processing applies a double band-reject filter to the audio (SoX "sinc" effect); 3 -> after the noise reduction the program additionally to the 2-processing applies fade-in and fade-out effects to the audio; _ -> is the same as 3.

If you specify as a second command line argument one of the numbers below the program behaves as follows: 0 -> the maximum amplitude, starting from which the file will not be trimmed for the first command line argument greater of 1, is 0.01; 1 -> the maximum amplitude, starting from which the file will not be trimmed for the first command line argument greater of 1, is 0.02; 2 -> the maximum amplitude, starting from which the file will not be trimmed for the first command line argument greater of 1, is 0.04; 3 -> the maximum amplitude, starting from which the file will not be trimmed for the first command line argument greater of 1, is 0.08; _ -> the maximum amplitude, starting from which the file will not be trimmed for the first command line argument greater of 1, is 0.04;

If you specify the third command line argument, it must be a list of Strings that can be obtained by executing the mmsyn7s program (https://hackage.haskell.org/package/mmsyn7s). The program will create just that non-silent representations for the Ukrainian sounds, which are given. The list must be sorted.

       ***** More Information *****

You can create a sound in either a 'sharp' mode or in a usual mode. The first one means that the program does not check whether the specified duration for recording the initial sound data is greater than 3 seconds. In such a case the duration can be much smaller. This mode needs more mastership in interacting with a program. For speech synthesis (as an advice) use this mode for the very short sounds (like the sound representation for "ь") or for the sounds, you can articulate for a long time continually (for example, vowels and some consonants). The 'sharp' mode delegates the responsibility for the sound to much broader extent to the user, so for a beginning it is not recommended (though you can give it a try).

At the beginning the program also creates a noise profile (once per execution). It is now used to reduce the noise level for the recorded sound representations. It uses the default SoX noise reducing settings with a hope that for you they can be sufficient. If you see that the program removes some sensitive and important sound data from the recorded by it sound representations, then you can specify as a first command line argument "-1". The program in such a case will create a noise profile as usual, but will not reduce the noise at all.

       ***** Ukrainian Localization *****

Please, before using the program check that uk_UA.UTF8 localization is present in your system as one of the system locales. Otherwise, the program will possibly (in some cases surely) cycle. In such a case, you can terminate it in a usual way by sending interruption signals.
