Many people feel speech recognition isn't good enough for every day use, but several devotees couldn't live without it. If you're looking to start using speech recognition, David Pogue has some tips to make it more effective.
David Pogue, writing for Scientific American, admits that speech recognition isn't perfect but that he's been able to achieve nearly 100 per cent accuracy with a few tricks. For starters, he recommends replacing the headset you're provided with because you can always find a better one. The more important takeaway, however, is to always correct the software by voice. When you type, it doesn't learn. We learn to understand language through repetition, so the software needs to learn that way as well. You want to teach it to learn your natural speech patterns, so be patient, talk normally, and correct by voice when necessary. This should, ultimately, make your speech recognition software work better than you expect.
