Google has announced a new innovation to its Google Now search allowing any correction if it misinterpreted spoken words. This feature is now available on both Android and iOS versions of the Google search application.
When the "OK Google" feature is used, the accuracy of the words seems to a challenge. According to Droid Life, it depends on many factors, such as quietness of the surroundings and clarity of speech. Therefore, the results can be inaccurate sometimes.
