Text 5. SPEECH RECOGNITION

In computer science, speech recognition (SR) is the translation of spoken words into text.

Some SR systems use "speaker independent speech recognition" while others use "training" where an individual speaker reads sections of text into the SR system. These systems analyze the person's specific voice and use it to fine tune the recognition of that person's speech, resulting in more accurate transcription. Systems that do not use training are called "speaker independent" systems. Systems that use training are called "speaker dependent" systems.

Speech recognition applications include voice user interfaces such as voice dialing, call routing, search, simple data entry, preparation of structured documents, speech-to-text processing, and aircraft.

The term voice recognition refers to finding the identity of "who" is speaking, rather than what they are saying. Recognizing the speaker can simplify the task of translating speech in systems that have been trained on specific person's voices or it can be used to authenticate or verify the identity of a speaker as part of a security process.

11. Match the following sentences with the inventions you have read:

1) It is the ability of a machine or program to identify words and phrases in spoken language and convert them to a machine-readable format.

2) The da Vinci Surgical System comprises three components: a surgeon’s console, a patient-side robotic cart with 4 arms manipulated by the surgeon (one to control the camera and three to manipulate instruments), and a high-definition 3D vision system.

3) As a first step, it needs to be trained with qualified samples so as to build a database of reference. Then the instrument can recognize new samples by comparing volatile compounds fingerprint to those contained in its database. This however may also provide a problem as many odors are made up off multiple different molecules, this may be possibly wrongly interpreted by the device as it will register them as different compounds.

4) It is connected to broadband internet and TV via wireless connection. 15" touch screen and pop-up keyboard. As if internet, email, phone, radio and MP3 player are not enough, Electrolux adds highly advanced calendar and video messaging system so the kitchen truly becomes the center hub in your house.
