1. A method for generating one or more wake-up words, the method comprising: receiving, using a keyboard, a text representation of the one or more wake-up words; determining a strength of the text representation of the one or more wake-up words based on one or more static measures, wherein the determining the strength of the text representation comprises applying a Kullback-Leibler (KL) divergence calculation between the one or more wake-up words and words unrelated to the one or more wake-up words; comparing a result of the KL divergence calculation to a predetermined distance score associated with a decoding accuracy of a speech recognizer; receiving, using a microphone, an audio representation of the one or more wake-up words; determining a strength of the audio representation of the one or more wake-up words based on one or more dynamic measures; and providing a message on a display device, wherein the message comprises one or more improvements to a likelihood that the speech recognizer recognizes the one or more wake-up words based on the strengths of the text and audio representations.
