Service “Allophone Plotter” allows to display the sound in graphic form. Using this service one has an opportunity to use allophones’ basis of online version text-to-speech synthesizer, select a specific allophone from the database and get its oscillogram – audio amplitude vs. time plot or spectrogram – plot of audio amplitude vs. time and frequency. Going to the service page (see Figure 1), the user can enter in the appropriate field the name of allophone, which graphical display he/she wants to get, or choose allophone from phonetic database in the drop-down menu.

When the user tries to get a spectrogram, he/she can choose its black-white or colourful view. After an allophone is chosen the user must press the button and wait until the service processes the information and generates the answer in html-page with the png-picture.
On Figure 2 you can see an oscillogram of the allophone “M002″. By the x-axis time changes are indicated, by the y-axis the amplitude of audio signal is shown.
The service can be used by phoneticians, linguists, students of philological and pedagogical specializations or just by interested people while learning and studying the Belarusian language.
