9. “ Speech ” EMPOWERED COMPUTING 8 Speech recognition- what is it? Speech recognition (in many contexts also known as automatic speech recognition, computer speech recognition or erroneously as voice recognition) is the process of converting a speech signal to a set of words, by means of an algorithm implemented as a computer program. Speech recognition applications that have emerged over the last years include voice dialling (e.g., Call home), call routing (e.g., I would like to make a collect call), simple data entry (e.g., entering a credit card number), and preparation of structured documents (e.g., a radiology report). Voice or speaker recognition is a related process that attempts to identify the person speaking, as opposed to what is being said.

12. “ Speech ” EMPOWERED COMPUTING 11 History of speech recognition

13. “ Speech ” EMPOWERED COMPUTING 12 Speech recognition- what can it do? Dictate, punctuate, format, correct recognition errors, edit text. Open programs, navigate menus, and click buttons Open, close and switch between applications E-mails Access files and folders Commands – built-in and custom (macros) to automate your work Surf the web Roaming Digital recorder

VERY ACCURATE - Up to 99% accuracy, never makes a spelling mistake, gets smarter the more you use it FASTER THAN TYPING! - Most people speak over 120 words per minute, but type less than 40 words a minute. Create letters and e-mails about three times faster than typing by hand! EASY TO USE - dictate letters, e-mails and surfing the web by voice very quickly. USE WITH ANY WINDOWS PROGRAM - Use voice to dictate, edit and control applications like Microsoft ® Word, Microsoft ® Excel, Microsoft Internet Explorer, and Corel ® WordPerfect ®. WIRELESS/BLUETOOTH SUPPORT - Use with certain Wireless and Bluetooth headsets. MOBILE - Dictate into a handheld device for automatic transcription when you synchronise with the PC.

It can never be 100% accurate Need to take time to:-  Learn the software  Speak clearly  Correctness recognised words  Add custom words and phrases Cannot transcribe conference recordings Can’t recognise a casual new user Caution over the claimed 120 words per minute wpm – see next chart “Watch outs”
