1st Software Associates offers a powerful tool for speech and sound processing and compression - Speech Master. In This applicationis  several original speech and sound compression algorithms are implemented. Main features:

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.

These features make Speech Master very useful tool for anyone who wants to organize their sound data in compressed archives. The dictionaries could be played back without limitations by  Speech Master trial version. That's why it is useful to distribute your sound data in compressed form and everybody could play them back with free  Speech Master trial version. Especially it is useful for the language education. The teacher could distribute lessons sound materials in the compressed form to the students. And the students could play them back unlimited number of times with free   Speech Master trial version. We want to note that the quality of the compressed speech is very high and the algorithms was specially developed for the high quality multimedia systems. Speech Master compression algorithms:

Algorithm  Source formats   Compression ratio
CELP 10400, lossy, speech only  8/16 bps 11025 Hz 8.5/17
Huffman, lossless 8 bps 11025-44100 Hz  2-3
CELP 22000, lossy, speech only 8/16 bps 22050 Hz 8.8/17.6

Applications of Speech Master:

Speech processing, phonogram recording, creating dictionaried and catalogs of sounds, music archives, compressing audio records, phonograms analysis, filtering sounds, storage of musical records and phonograms, musical education, language education.

System Requirements:

Required: 486 or faster processor, Windows 95 or Windows NT 4.0, 12 MB RAM, 10 MB available hard disk space, 256-color display adapter.

Recommended:
Pentium ® processor, Windows 95, Windows 98, Windows NT or higher, 32 MB RAM or more, 20 MB available hard disk space or more, 24-bit display adapter at 1024x768 resolution. Some system requirements may vary depending on the size of the images processed. Available memory should be at least four times the uncompressed image size. Multi level undo is limited by the available hard disk space.
