Hybrid Recognizer of Isoladed Words
Veselý, Karel ; Černocký, Jan (referee) ; Grézl, František (advisor)
The speaker independent isolated words recignizer has various practical applications. For example it can be used to control home gadgets by PC. Even more interesting is possibility that it can be built in the user interface of any application or even into operating system to perform command based control such as invocation of applications, or execution of any other specific action. The most remarkable application of isolated recognition is in electronical dictionaries. A voice controlled word lookup could be new feature of the next generation dictionaries. Very useful is the ability to ouptut ordered list of the most likely words, which gives the user ability to learn and distinguish similar words.

Database of recordings for detection of voice activity
Pelikán, Pavel ; Hudec, Antonín (referee) ; Míča, Ivan (advisor)
This thesis deals with voice activity detection (VAD) and requirements for creating a speech database. One of the existing tools for marking recordings was chosen. On the basis of the gained knowledge, database of isolated words, sentences, text and spontaneous speech was created. The practical part consists of a detailed description of database and mark creation. Furthermore, the thesis deals with the conversion of marks into Matlab. There are also some auxiliary scripts for operations with marks. Prepared and a database was created in an anechoic chamber and includes recordings from 16 speakers.
