The University of Milano Bicocca 3D face database is a collection of multimodal (3D + 2D colour images) facial acquisitions. The database is available to universities and research centers interested in face detection, face recognition, face synthesis, etc. The UMB-DB has been acquired with a particular focus on facial occlusions, i.e. scarves, hats, hands, eyeglasses and other types of occlusion wich can occur in real-world scenarios.

Multimedia: Audio, Video, Speech Synthesis and Recognition

Most speech recognition algorithms rely only on the sound of the individualwords, and not on their context. They attempt to , but not to. This places them at a tremendous disadvantage comparedto human listeners. Three annoyances are common in speech recognitionsystems: (1) The recognized speech must have distinct pauses between thewords. This eliminates the need for the algorithm to deal with phrases thatsound alike, but are composed of different words (i.e., and ). This is slow and awkward for people accustomed to speaking in anoverlapping flow. (2) The vocabulary is often limited to only a few hundredwords. This means that the algorithm only has to search a limited set to find thebest match. As the vocabulary is made larger, the recognition time and errorrate both increase. (3) The algorithm must be on each speaker. Thisrequires each person using the system to speak each word to be recognized,often needing to be repeated five to ten times. This personalized databasegreatly increases the accuracy of the word recognition, but it is inconvenientand time consuming.

The prize for developing a successful speech recognition technology isenormous. Speech is the quickest and most efficient way for humans tocommunicate. Speech recognition has the potential of replacing writing,typing, keyboard entry, and the electronic control provided by switches andknobs. It just needs to work a little better to become accepted by thecommercial marketplace. Progress in speech recognition will likely come fromthe areas of artificial intelligence and neural networks as much as through DSPitself. Don't think of this as a technical ; think of it as a technical .

Nearly all techniques for speech synthesis and recognition are based on themodel of human speech production shown in Fig. 22-8. Most human speechsounds can be classified as either or . Voiced sounds occurwhen air is forced from the lungs, through the vocal cords, and out of the mouthand/or nose. The vocal cords are two thin flaps of tissue

The Bosphorus Database is a new 3D face database that includes a rich set of expressions, systematic variation of poses and different types of occlusions. This database is unique from three aspects: (1) The facial expressions are composed of judiciously selected subset of Action Units as well as the six basic emotions, and many actors/actresses are incorporated to obtain more realistic expression data; (2) A rich set of head pose variations are available; (3) Different types of face occlusions are included. Hence, this new database can be a very valuable resource for development and evaluation of algorithms on face recognition under adverse conditions and facial expression analysis as well as for facial expression synthesis.

For this purpose, we will use the SpeechRecognitionEngine class instead of the SpeechRecognizer class. A huge difference between the two is that the SpeechRecognitionEngine class doesn't require the Windows speech recognition to be running and won't take you through the voice recognition guide. Instead, it will use basic voice recognition and listen only for grammar which you feed into the class.
