| |
| − | | |
| − | * A good microphone connected the PC
| |
| − | * A quiet room with good acoustics
| |
| − | * A program for recording and editing audio.
| |
| − | ** Many commercial programs can be bought for money.
| |
| − | ** Audacity - http://audacity.sourceforge.net/?lang=en is usable program which is free as both in "free speech" and "free beer", and is cross-platform.
| |
| − | | |
| − | == Editing of [[ASVP DES-file]] ==
| |
| − | Any text edior. http://www.pspad.com/en/ is a good one (''Free as in "free beer"'').
| |
| − | | |
| − | == ASVP Packaging ==
| |
| − | These tools are required by the AlphaVoc 2 toolchain it self.
| |
| − | | |
| − | * '''sox''' - Sound eXchange - http://sox.sourceforge.net/
| |
| − | * A unix/linux like environment. For windows the following two alternatives are tested:
| |
| − | ** '''Cygwin''' - http://www.cygwin.com/ - Recommended. Only "base" package needed (+ utils/bzip2?).
| |
| − | ** MSYS - http://www.mingw.org/wiki/msys - Easy install and only 8MByte on disk. But very minimal functionality.
| |
| − | *** Proper linux may also be used, but contact Zenitel to get linux versions of the Zenitel provided programs.
| |
| − | *** The "unix" programs needed are: '''bash''', '''tar''', bzip2, md5sum, fgrep, sed, rm, mv.
| |
| − | | |
| − | ''All these tools are free as both in "free speech" and "free beer".''

| − | | |
| − | =Tools provided by Zenitel=
| |
| − | | |
| − | Two commandline programs (.exe files built for Windows):
| |
| − | * '''svp_des2bin''' converts a DES-file to a binary file with the message-descriptions in binary table format. It also has an option to list all wav-files referenced by the DES-file. (The same program is also used inside {{AlphaWiki|AMC-IP}}).
| |
| − | * '''svp_build_message''' is a test program, simulating the ASVP function in {{AlphaWiki|AMCD}}. Given a binary ASVP voice file, a [[SVP reference]] plus optionally a parameter, it will list names of the WAV-files which will be played by AlphaCom.
| |
| − | | |
| − | [http://en.wikipedia.org/wiki/Bash Bash] scripts :
| |
| − | * '''build.sh''' builds a ASVP package from a DES-file and the WAV files referenced by the DES-file. It uses svp_des2bin to get the list of WAV files to add to the packacge, and sox to convert the WAV files to MS-ADPCM coding.
| |
| − | * '''build_all_sources.sh''' can be used pack all orignal WAV files and the DES file into a single huge archive file for exchange with others.
| |
| − | *'''play_test.sh''' uses svp_build_message and sox to play a message on the PC speaker given a package name, a [[SVP reference]] plus optionally a parameter.
| |
| − | | |
| − | =Installation on Windows=
| |
| − | *Install '''cygwin''': Download http://www.cygwin.com/setup.exe. Run it, and accept all default options. Choose a mirror site on your continent for package download.
| |
| − | ** See [[Cygwin for dummies]]
| |
| − | *Install '''sox''': Goto http://sox.sourceforge.net/, find "MS-Windows executable" and download zip-file. Unpack the zipfile, and copy sox.exe to /usr/local/bin/ (C:\cygwin\usr\local\bin\).
| |
| − | *Get '''AlphaVoc2.zip''' from ''zenitel-url-to-be-decided'' (now \\nooslzsfl01\css_main\CSS_Development\Transfer\ASVP_IP_packages_prelim). Unzip, and copy svp_build_message.exe and svp_des2bin.exe to /usr/local/bin/ (C:\cygwin\usr\local\bin\)
| |
| − | *Get '''asvp_all_sources.tbz2''' (55MByte) from Zenitel. This is the complete archive of all ASVP language projects supported by Zenitel. Make a folder 'asvp' under hour home directory, /home/<your-login>/asvp (C:\cygwin\home\<your-login>\asvp), and put the archive here. Unpack with the following command in cywin in your home folder:
| |
| − | | |
| − | cd ~/asvp
| |
| − | tar -xf asvp_all_sources.tbz2
| |
| − | | |
| − | The build.sh, build_all_sources.sh, play_test.sh scripts are included in asvp_all_sources.tbz2.
| |
| − | | |
| − | =Naming conventions and directories=
| |
| − | | |
| − | ASVP Packages have a name. Standard language packages are named after the ISO_639-1 code for the language. 'en' for English, 'fr' for French and so on.
| |
| − | | |
| − | Custom packages should use longer names. Suggestion: 'fr_BNP' for hypothetical French messages for customer BNP.
| |
| − | | |
| − | *The ASVP DES file ''must'' have the name asvp_''<package-name>''.des, eg. asvp_'''en'''.des
| |
| − | *The wav files ''should'' be placed under folders wav/''<package-name>''. Eg. wav/en
| |
| − | *The wav file names ''should'' start with the package name.
| |
| − | | |
| − | The naming conventions on existing wav files are not perfect, but this is almost followed: "deg9i1.wav" means language "de", '''g'''roup 9, '''i'''ndivid 1.
| |
| − | | |
| − | =Usage=
| |
| − | ==Recording messages==
| |
| − | Details outside the scope of AlphaVoC, but some guidelines:
| |
| − | * Record the messages in a quiet room with good acoustics. Adjust the volume on the recording device so that it so loud as possible but with no clipping. Read every message three times.
| |
| − | * Samplerate 16000, Channels Mono, Resolution 16-bit.
| |
| − | * Cut the voice messages into reusable fragments in the audio editor.
| |
| − | * Save the voice fragment to WAV files, PCM, 16kHz. The names of the wav files goes into the DES file.
| |
| − | ** Consider: Use the audio editor to normalize the audio fragments. Max amplitude 2 to 3dB below max allowed signal is recommended. Remove DC offset.
| |
| − | * Save backup of wav files often!
| |
| − | | |
| − | == DES file==
| |
| − | Copy an existing DES file. Use the a des file of the same language, or a related language, as template.
| |
| − | | |
| − | Open the .des file in an text editor. Edit the wav file names, and if necessary, other parts.
| |
| − | '''build.sh''' copies the "VERSION:" and "DESCRIPTION:" header fields to the package.info [[APKG]] header. The version number is also used to form the filename of the package file.
| |
| − | | |
| − | ==build.sh==
| |
| − | Produces both [[APKG]] file and a [[AlphaSys Package Format]] legacy file.
| |
| − | [[Category:ASVP]] | |
| − | | |
| − | | |
| − | Invoke the build.sh script with the package name as parameter:
| |
| − |
| |
| − | build.sh '''en'''
| |
| − | | |
| − | Final output files appear in folder z_package_out.
