AlfaNum is an innovative company gathering a team of experts which, for the past 15 years, has been striving to bring the world of modern speech technologies closer to a wide range of users. Until today the company has developed software components for high quality speech recognition and synthesis in Serbian, Croatian and Macedonian. In the development of these technologies, which were originally intended for the visually impaired, AlfaNum has established itself as the leader in the region. More information on these software components can be found on our products and services pages, and they can also be tested on our demo pages. Besides speech technologies, AlfaNum also works on the development and implementation of products intended for the disabled, as well as the implementation of call centres, information centres and databases. If you are considering an upgrade to your system based on cutting-edge speech technologies or you need some other expert service in the field, feel free to contact us and we will justify your confidence. As a result of the recent progress in computer technology, the personal computers of today are sufficiently efficient to recognize speech with high accuracy and synthesize speech of high quality. Furthermore, their relatively low price allows a wide range of users to feel the benefits of speech technologies. On the other hand, South Slavic languages are extremely complex and each one has its own particularities, which makes the development of speech technologies for any of these languages quite a difficult task. Furthermore, relatively small and closed markets related to each of these languages are an additional reason for which none of the leading companies in the world has attempted to develop speech synthesis or recognition for them until lately. Having recognized this potential strategic advantage in time, we have begun the development ourselves and achieving main objectives and activities. The development of flexible text-to-speech synthesis (TTS) of high quality The development of large vocabulary continuous automatic speech recognition (ASR) The development of speaker identification and verification systems The research and development of emotion speech recognition The development of speech morphing systems The development of natural language processing modules including dialogue management The application of the developed speech technologies in Western Balkan countries: in multimodal human-machine dialogue systems (IVR, smart phones, smart homes) for purposes such as: text reading, text dictation, speech transcription within aids for the physically disabled, visually impaired, speech impaired, hearing impaired. Scientific research and development within the AlfaNum team are carried out by a group of experts working at the Department of Communications and Signal Processing at the Faculty of Technical Sciences in Novi Sad, Serbia.
