Evolution of speech recogniton

Why type? –  speech is faster!

I found an interesting Infographic a few days ago which I would like to share to you. This one is one year old, but as we look at history of speech recognition – nothing has changed.


Here, you can see that the technology of Automatic Speech Recognition (ASR) has developed a lot since the Voder from AT&T in 1936. Today, we use Apple’s SIRI and there are actually some more solutions from Google and Microsoft and for sure, Nuance has done some great new stuff.

Need more background knowledge about speech recognition?

voice compass - book 3 - German languageI do a book series called voice compass, in which I cover all relevant background information concerning speech technology. Since 2006, the aixvox team has been collecting examples, information about the major players and concepts in speech.

The voice compass is the compendium of Information and Communications Technology (ICT) and adresses the domain of voice, i. e. speech applications on the telephone in full detail. Nowadays, every businessman, entrepreneur, manager or decision maker needs to be informed about the possibilities regarding voice applications. The voice compass gives a compact account thereof.

    Nice history of Speech Recognition including the fun Speak & Spell toy!

  2. I worked for Lanier for a number of years, and we hooked up voice recognition to our VoiceWriter dictation equipment to produce medical transcriptions.

  10. Detlev, this is a great post. Just in the past couple of years I find myself using speech recognition more and more. I especially like using it on the iPhone when I’m composing a text message or quick email on the run. You can accomplish so much without typing at all.

    In the early days of the Mac (Power PC era) you could ask the Mac what time it was, or to open a document or print, etc., and it was very cool (It also talked back).

    Google voice search is absolutely amazing. And the MotoX has some amazing abilities, too!

    I wonder if eventually voice recognition will have built-in grammar, spelling and punctuation?
