Moram priznati da dugo nisam koristio nikakvu vrstu prepoznavanja govora kada su me zamolili da radim tutorijale. Posljednji put kad sam isprobao prepoznavanje govora, bilo je to s Dragon Dictateom^{(Dragon Dictate)} , što je bilo novo kada je i Windows 98 bio nov. Jako davno u kompjuterskim godinama!

Bio sam sretan što sam se pozabavio ovom temom jer me jako zanimalo kako se poboljšalo prepoznavanje govora. I dečko, je li se popravilo! Čak je i osnovna, ugrađena aplikacija poput ove odradila nevjerojatno dobar posao "iz kutije". U ovom završnom članku o prepoznavanju govora^{(Speech Recognition)} želio bih govoriti o tome što sam naučio dok sam se ponovno upoznavao s čudima prepoznavanja govora i kamo ću dalje krenuti.

Još nisam spreman za Zvjezdane staze

Siguran sam da su mnogi od nas gledali posadu Starship Enterprisea^{(Starship Enterprise)} kako govori "Computer!"i odmah dobiti odgovor. Još nemamo računala Zvjezdane flote^(Starfleet) , ali počevši od sustava Windows Vista^{(Windows Vista)} i nadalje u sustavu Windows 7^{(Windows 7)} , imamo računala koja će nas slušati i odgovoriti na ono što im kažemo — i odgovoriti nam ako "Što je to?" ^{("What was that?")}smatra se odgovorom.

Imao sam problema kada sam prvi put pokušao koristiti prepoznavanje govora^{(Speech Recognition)} , a rješavanje problema nije bilo posebno jednostavno. Datoteke pomoći nisu uvijek dovoljno korisne. Odgovore sam uspio pronaći na Microsoftovoj^(Microsoft) web stranici i u nizu online foruma bez previše rada. Tako sam saznao da sam zaboravio da moja web kamera (koja je sjedila točno ispred mene na vrhu mog monitora i izravno u skladu s načinom na koji sam govorio) također ima aktivan mikrofon i stvarala je zabunu. Nakon što sam to popravio, od tada je bilo prilično glatko.

Čak sam pokušao govoriti s nizom različitih naglasaka ( BBC-jev britanski^{(BBC British)} i američki^(American) seljak, na primjer) i uspio sam dobiti razumno dobro prepoznavanje, dopuštajući razlike u standardnom američkom^(American) izgovoru. Naravno, govoreći "Friends, Romans, countrymen, lend me your ears!"dok sam ostavljao najbolje dojmove o Helen Mirren i Jeffu ​​Foxworthyju^{(Jeff Foxworthy)} previše me nasmijao da bih dobio potpuno točne rezultate.

Prepoznavanje jezika

Prepoznavanje govora^{(Speech Recognition)} se može koristiti s različitim jezicima i mislio sam da bih ga mogao isprobati sa svojim ograničenim, s američkim^(American) naglaskom, španjolskim^(Spanish) , njemačkim^(German) i francuskim^(French) , ali nažalost ne možete koristiti druge jezike osim ako vaš operativni sustav također nije na tom jeziku. Jezik operativnog sustava možete promijeniti instaliranjem drugog jezičnog paketa od Microsofta^(Microsoft) , ali to možete učiniti samo ako koristite Windows 7 Ultimate ili Windows 7 Enterprise.

Prepoznavanje govora^{(Speech Recognition)} dostupno je za američki engleski^{(US English)} , britanski engleski^{(UK English)} , francuski^(French) , španjolski^(Spanish) , njemački^(German) , japanski^(Japanese) , tradicionalni kineski^{(Traditional Chinese)} i pojednostavljeni kineski , a naći će se u verzijama sustava ^{(Simplified Chinese)}Windows 7 za te jezike (sve verzije). Bilo mi je žao što to nisam mogao isprobati. Nemam pojma što će se dogoditi sa sustavom Windows 8^{(Windows 8)} , ali mislim da bi mogućnost instaliranja drugih jezičnih paketa bila dobar dodatak Windows 8 ekvivalentima Windows 7 Professional i novijim.

Ono što dobro funkcionira

Kao što sam spomenuo, prepoznavanje govora^{(Speech Recognition)} je dizajnirano da najbolje radi s drugim Microsoftovim^(Microsoft) softverom. Sve dok sam eksperimentirao s Microsoftovim^(Microsoft) proizvodima bio sam vrlo uspješan (iako je, kako se moglo očekivati, korištenje Microsoft Office Excela^{(Microsoft Office Excel)} bilo je i ograničeno i komplicirano). S drugim softverom je pogodio ili promašio. Mogao sam prilično dobro koristiti preglednik Google Chrome (definitivno ne tako dobro kao Internet Explorer ) i svoj program za e-poštu Eudora , koji je do sada prilično starinski softver. Vrijedi eksperimentirati s vlastitim omiljenim softverom da vidite što možete učiniti. Naredba "prikaži brojeve" bila je posebno korisna u odabiru stavki i naredbi.

Također sam otkrio da nije trebalo dugo da se točnost prepoznavanja značajno poboljša. Dva puta sam prošao vježbe treninga i nakon toga je prepoznavanje bilo gotovo 100% točno. Mogao sam govoriti malo brže i stavljao manje pauza kako bi softver mogao držati korak. Zaista sam uživao gledati moj glas preveden u riječi na ekranu. Moja rana iskustva sa softverom za prepoznavanje govora nisu bila ni blizu ovako ugodna.

Što ne radi dobro

Kao što sam spomenuo, neki softver jednostavno nije kompatibilan s prepoznavanjem govora^{(Speech Recognition)} . Nisam mogao ni otvoriti Adobe Reader ili Adobe AIR verziju TweetDecka^(TweetDeck) . Otkrio sam da se ne mogu prijaviti na svoj Google račun s Internet Explorerom^{(Internet Explorer)} kako bih isprobao Google dokumente^{(Google Docs)} — činilo se da ne postoji način da izgovorim ili napišem svoju lozinku. Pretpostavljam da je to sigurnosni problem, ne dopuštajući da se lozinke izgovaraju naglas gdje bi netko drugi mogao čuti, ali bilo je neugodno.

Mogao sam otvoriti iTunes i odabrati pjesmu za reprodukciju, ali je nisam mogao pokrenuti. Mogao sam otvoriti Scrivener (moj program za obradu teksta po izboru), ali "Prikaži brojeve"^{("Show numbers")} nije prekrivao brojeve na bilo čemu što sam želio koristiti. Nisam napravio nikakve opsežne eksperimente sa svojim omiljenim softverom - to su samo neki koje sam isprobao. Bilo bi vrijedno za svakoga tko želi koristiti prepoznavanje govora^{(Speech Recognition)} da testira programe s kojima ga želi koristiti, kako bi bio siguran da će biti kompatibilan.

Zamotavanje

Zaista sam uživao raditi s prepoznavanjem govora^{(Speech Recognition)} i diviti se poboljšanjima koja su učinjena tijekom vremena. Zasigurno bi bio dovoljno dobar za ležernu svakodnevnu upotrebu, posebice s Microsoftovim^(Microsoft) proizvodima.

Hoću li nastaviti koristiti prepoznavanje govora^{(Speech Recognition)} ? Da, kad mogu. U ovom trenutku mi ne treba ništa sofisticiranije. Bilo je itekako vrijedno vremena koje je bilo potrebno da ga treniram i treniram sebe da ga pravilno koristim.

Speech Recognition: Afterthoughts on Its Strengths and Weaknesses

I have to admit that I hadn't used any kind of speеch recognition in a lоng timе when I waѕ аsked to do the tutorials. Thе last time I had tried speech recognition, it was with Dragon Dictate, which was new when Windows 98 was also new. A very long time ago in computer years!

I was happy to tackle this subject because I was very interested to see how speech recognition has improved. And boy, has it improved! Even a basic, built-in application like this did an amazingly good job "right out of the box." In this final article about Speech Recognition, I'd like to talk about what I learned while reacquainting myself with the wonders of speech recognition, and where I'll be going from here.

Not ready for Star Trek yet

I'm sure many of us watched the crew of the Starship Enterprise saying "Computer!" and getting an immediate answer. We don't have Starfleet computers yet, but beginning with Windows Vista and continuing in Windows 7, we do have computers that will listen to us and respond to what we tell them—and answer us, if "What was that?" is considered an answer.

I did have problems when I first tried to use Speech Recognition, and troubleshooting wasn't particularly straightforward. The help files are not always helpful enough. I was able to find the answers on Microsoft's web site and in an assortment of online forums without too much work. That's how I found out that I had forgotten that my webcam (sitting right in front of me on top of my monitor, and directly in line with the way I was speaking) also had an active microphone and was adding to the confusion. Once I fixed that, it was pretty smooth sailing from then on.

I even tried speaking with an assortment of different accents (BBC British and American redneck, for example) and was able to get reasonably good recognition, allowing for differences in standard American pronunciation. Of course, saying "Friends, Romans, countrymen, lend me your ears!" while doing my very best impressions of Helen Mirren and Jeff Foxworthy made me laugh too much to get entirely accurate results.

Language recognition

Speech Recognitioncan be used with different languages, and I thought I might try it out with my limited, American accented, Spanish, German and French, but unfortunately you cannot use other languages unless your operating system is also in that language. You can change your operating system's language by installing another language pack from Microsoft, but you can only do that if you're running Windows 7 Ultimate or Windows 7 Enterprise.

Speech Recognition is available for US English, UK English, French, Spanish, German, Japanese, Traditional Chinese and Simplified Chinese, and will be found in those languages' versions of Windows 7 (all versions). I was sorry not to be able to try that out. I have no idea what will happen with Windows 8, but I think the ability to install other language packs would be a good addition to the Windows 8 equivalents of Windows 7 Professional and above.

What works well

As I mentioned, Speech Recognition is designed to work best with other Microsoft software. As long as I experimented with Microsoft products I was very successful (although as one might expect, using Microsoft Office Excel was both limited and complicated). With other software it was hit or miss. I could use the Google Chrome browser fairly well (definitely not as well as Internet Explorer) and my Eudora email program, which is pretty much antique software by now. It's worth experimenting with your own favorite software to see what you can do. The "show numbers" command was especially helpful in selecting items and commands.

I also found that it didn't take very long for the accuracy of the recognition to improve markedly. I went through the training exercises twice, and after that the recognition was almost 100% correct. I was able to speak a little faster and put in fewer pauses for the software to keep up. I really enjoyed watching my voice translated into words on the screen. My early experiences with speech recognition software were nowhere near this pleasant.

What doesn't work well

As I mentioned, some software is just incompatible with Speech Recognition. I couldn't even open Adobe Reader or the Adobe AIR version of TweetDeck. I found that I could not sign into my Google account with Internet Explorer to try out Google Docs—there seemed to be no way to speak or spell my password. I suspect this is a security issue, not allowing passwords to be spoken out loud where someone else might hear, but it was annoying.

I could open iTunes and select a song to play, but could not actually get it to play. I could open Scrivener (my word processor of choice) but "Show numbers" did not overlay numbers on anything I wanted to use. I didn't do any really extensive experimentation with my favorite software—those are just a few that I tried. It would be worthwhile for anyone who wants to use Speech Recognition to test out the programs they want to use it with, to be sure it's going to be compatible.

Oddly, it's almost impossible to find any information about Speech Recognition on the Microsoft Answers web site without clicking a link from a Google or Bing search. I was unable to get any answers at all by putting "Speech Recognition" into the search box, even though there are a few questions about it in the forums. Use this link to get Speech Recognition help from the Windows web site: Speech Recognition search results.

Here's a brief Wikipedia article that talks about the history of speech recognition at Microsoft: Windows Speech Recognition.

Here is a blog entry that gives the author's thoughts on comparing Speech Recognition with Dragon Naturally Speaking: Dragon NaturallySpeaking Versus Windows 7 Voice Recognition.

Wrapping it up

I really enjoyed working with Speech Recognition and marveling at the improvements that have been made over time. It would certainly be good enough for casual everyday use, especially with Microsoft products.

Will I keep using Speech Recognition? Yes, when I can. At this point I don't need anything more sophisticated. It was well worth the time it took to train it and to train myself to use it right.
