WELCOME to Speech Processing Laboratory (SPL)

SPL is one of the research laboratories of Computer Engineering Department of Sharif University Of Technology. The main area of the research in this Lab is Digital Signal Processing, specially Speech signals. Speech Recognition is the major field of activity for this group and a speech recognition engine including the latest and successful algorithms is developed. This engine is customized for Persian language including Persian language models (Statistical and Grammatical) and the first version is released as NEVISA, the most robust and accurate Persian dictation system. SPL also developed NEWSHA (T-NEVISA), the high accurate Persian telephony speech recognition including command and digit recognition. Some of derived products from these engines are:

Other speech-based solutions are available on the lab's partner ASR Gooyesh Pardaz Co. web site.
