1 Speech Recognition

2 My computer doesn’t understand me……….. Software is now mainstream Many people use it within office/home setting for inputting text. For people who have difficulties with a keyboard possibly hands free or for people who have difficulty with spelling.

3  still need to ‘think before you speak’. Um and Errors don’t make for good recognition!  Dictating phrases into the computer. Requires reasonably clear speech. Speech Recognition Software  Speech Recognition is better at putting correct context text within a sentence e.g. OFF and OF, so may be better for someone who has literacy difficulties

4 Speech Recognition  Spotting mistakes and correcting them is important as consequent accuracy improves.  Text to Speech system can help with spotting mistakes. Recorded Speech can tell what actually dictated.  Does the correction box offer me word prediction as I spell the word I am correcting? Correcting

5 Speech Recognition A high specification of computer is required. Noise & confidentiality can be an issue Remember computers are not infallible and neither is Speech Recognition. However, accuracy of up to 99% can be achieved. If correction is a problem for some users, extra help and support may be required building up speech file. What applications do I want to use on the computer? Word, Email, Internet – Be aware that it may not work in some non Windows based programs & the version of the Operating System running may be important. Pros and Cons

6  Word is either right or wrong, not misspell Speech Recognition  Enables the user to use the computer ‘hands free’ as possible by controlling computer and mouse.  Able to input ideas into the computer without worrying about how to spell words.  Allows recording using external source to transcribe into computer i.e. digital dictaphone Pros and Cons

7 User needs to enrol by reading a passage of text aloud through the microphone. Speech Recognition Which type of microphone will work best for me? Headset, Gooseneck, wireless, combined telephone headset, mobile phone/Dictaphone etc. Do I require macros for dictation and commands ie record keystrokes for speed? Once this had been done and the speech model has been set up, you’re ready to start!

8 Speech Recognition Software Most smart phones have speech recognition built in Speech recognition built into Windows Vista and 7/8 iListen built into Mac Operating System Free downloadable VoxForge http://www.voxforge.org/ to work with Windows, Mac and Linux Operating systemshttp://www.voxforge.org/ Dragon Naturally Speaking V.12/MacSpeak Voice recognition built into Grid 2 – useful for those with unclear speech, as compare what is said to choices on screen rather than full dictionary.
