Voice Typing In Google Docs
Google recently introduced a feature to Google Docs called ‘Voice Typing’. If you are using ‘Google Now’ in android phones, then surely you know that Google has a wonderful speech to text processing engine. Both online and offline speech processing is extraordinary. Whatever your accent/lingo is, Google’s speech to text processing engine produces right result almost all the times. It is capable of processing a human conversion, not a pre-defined voice command.
Apparently it is not so much difficult for Google to extent this feature to Google Docs. Now you can dictate words to type-in in your online docs on Google Drive.
You can find this option under “Tools” menu once you open a Doc file online. Much to the surprise it can support typing in punctuation through voice.
