| My first introduction to Dragon
NaturallySpeaking was an older version that came with Corel WordPerfect Suite 8 Legal
Edition. Once I was able to get the older version installed, I quickly abandoned using the
software because its accuracy was miserable. So I expected a similar experience with this
version, but I was pleasantly surprised. Training Unfortunately, training doesnt insure the software will accurately translate your speech. Additional correction steps are required to assist the software in its task including: 1) Quick Correct list; and 2) Correction dialog box. Both mechanisms assist the software to better recognize speech by correcting errors as they appear. Although NaturallySpeaking recognizes individual words, its real power is in its ability to recognize phrases. In fact, its the ability to recognize phrases that allows the software to choose the correct word from many similarly sounding words. To this end, the software includes a Vocabulary Builder, which analyzes your existing documents for the software to predict what words you are saying based on previous writings. Accuracy The Legal Edition includes a 250,000-word vocabulary with specialized legal terms, Latin and French law phrases, court names and abbreviations. Because context is extraordinarily important for NaturallySpeaking, its accuracy is directly tied to the type of training performed and the vocabulary file selected. For example, I found the program did an excellent job when dictating formal letters, but did an average job when dictating personal letters. The higher error rate when dictating personal letters is understandably tied to the fact the program setting was expecting formal business/legal jargon, rather than informal speech. [Before Training 7
errors] After a few hours of thorough training there were no errors when dictating the above message. Compatibility/Usability The first program I tested Dragon NaturallySpeaking on was Microsoft Office XP. The most notable difference between using the software with a program such as Office XP versus DragonPad was the responsiveness of the speech recognition engine. While accuracy was not affected, it took longer for the text to appear on screen after the phrase was spoken. The second program I tested was Corel WordPerfect 2000.
The software does its job well, however, I did experience an anomaly when I said the
number 12. Rather than typing the number 12, the font size pull-down menu (which was
currently set to a 12 point font) appeared. Apparently, the software interpreted my speech
as a command to change the font size. The only major problem I encountered with the software
was when I attempted to load Matthew Bender Authority, a 16-bit application using the
Folio engine. With NaturallySpeaking loaded, Matthew Bender Authority would not load. SpeechDocs Filler Its unlikely a law firm already using a document management system would replace its system with SpeechDocs Filler. However, lawyers or firms without document management systems in place might find SpeechDocs Filler valuable. Mobile Feature NaturallySpeaking recommends, however, that in order to increase accuracy the user speak into the included headset microphone rather than talking into the built-in microphone of the users recorder. |
I have been using Dragon NaturallySpeaking since Version 3. It has been a
solid product since Version 4. But Version 4 was not compatible with Windows ME or Windows
2000. Aside from making the program compatible with Microsofts two newest operating
systems, the improvements in Version 5 are evolutionary rather than revolutionary. Installation is accomplished by the now standard install shield wizard. The program installed without a hitch on every computer with every operating system I installed it on. I would recommend at least a Pentium II 350 MHz computer system with a good quality sound card, or Universal Serial Bus (USB) microphone (which bypasses the sound card). Training The initial training, where the software adapts to your voice by listening as you read one of five stories, takes less than 10 minutes. For most people on most computers this is all the formal training necessary. Training is the process by which the software associates the sounds you make with the words it expects to hear. Accuracy This isnt to say the software will always give you 100 percent accuracy after the training. If you say a word that isnt in the softwares vocabulary, or more likely, if you say a word in the softwares vocabulary differently from how the computer expects to hear it, the software will not accurately recognize your speech. For the software to learn your speech, you must detect the mistake, and correct it in a particular manner. This all can be done by voice command, but there will be times when its simply easier to use the keyboard. Two distinct features are useful in the correction process. First, the software can play back your speech to help you remember exactly what you said. With the play feature, you hear what you said, not what the program typed. The software also has an extremely useful text-to-speech capability. This feature will read what the software typed in a British computer voice. The default speed of this British reader is too fast for my taste. You can slow him down by changing the softwares text-to-speech options. NatuallySpeaking transcribes exactly what you say even if it makes no sense in English or uses nonexistent or inappropriate words. The most common omissions are the small connecting words such as the, it, and, etc. Often, these words are not properly enunciated in ordinary speech. A good secretary would fill in these words whether you say them are not, but the software will not. Subjectively, Version 5 is slightly more accurate than Version 4. Compatibility/Usability SpeechDocs Filler Mobile Feature Training for the new user is done on the recorder. Once the recorder dictation is transferred to the computer and recognized, it can be corrected completely with voice commands just like dictation through a microphone connected to the computer. If you are a proficient typist, this is the best use of the Dragon NatuallySpeaking. If you dont type well, or if you are disabled, the software is even more useful. The Legal Edition of the software contains a vocabulary enhanced to include legal terms. This means that the software is more likely to recognize a legal term the first time you use it. Even without the legal vocabulary, the software can learn legal terms just like it can learn any other word. You also can control your computer with voice commands, and create custom voice commands. All in all, Version 5 is an extremely useful program. |
