STC has an excellent reputation in high-tech market, designing algorithms for high performance of speech processing applications.

Speech Technology Center develops manufactures and markets software and hardware solutions, standalone devices, DSP boards and software toolkits. STC’s products are based on proprietary patented technologies.

Clear Voice – proprietary, original state-of-the-art algorithm which has been developed to automatically
remove ambient noise from voice and other previously recorded or transmitted sound signals.
VoiceCom – algorithms of voice command control for SAPI. Language-independent and speakerindependent technology allows operating computer and other electronic devices by means of voice.
Voice Key – voice-based access restriction algorithm. Voice Key authenticates user by voice password and in 0,5 sec time spam allows to identify user and differentiate access rights to information and services.
VoiceNet SDK - Speaker-independent and language-independent automatic identification technology.
Orator – Speech synthesis application converting text to speech for Russia, without requirement of text preparation beforehand . Various samples of intonation models are used to make this technology “top of the list”. “Orator” is applied in IVR (Interactive Voice Response) systems, inquiry and information services, call-centers and messaging systems, consumer and professional products.
Sound Stretcher – technology that allows playback of speech in variable speed (fast/slow) without distorting voice pitch for natural sound. Speed alteration function allows performing the tasks quicker and easier. Sound Stretcher algorithm also allows more efficient use of the advertisement airtime.
Reverb Clipper – new technology of reverberation distortions compensation. Increases speech signal clarity recorded indoors with reverberation time up to 3 seconds.
Denoiser DSP board – allows integration of modern technology broadband noise filtering in any type of audio processing, transmission or recording equipment.
Voice Detect – speech detection algorithm, applied for quick retrieval of speech in lengthy recordings.
Jingle Tracker (Music Spotting) - original state-of-the-art algorithm which has been developed to spot music samples in a sound stream. Jingle Tracker allows to spot radio advertisement, report or music composition while on-air.
Audio Data Mining – this unique technology allows user to dynamically mine through audio content for specific information without tedious listening of complete file.
EdiTracker – state-of-the-art technology of record authentication.
