Abstract: A voice response method, apparatus and intelligent device are disclosed. The method includes: receiving voice information sent by a user; determining whether the voice information contains a wake-up word; and if so, outputting a response voice according to a preset response rule. Thus, if there is a wake-up word in voice information received by the intelligent device, the intelligent device outputs a response voice according to a preset response rule. That is, after the user sends a wake-up word, the intelligent device outputs a voice to respond to the wake-up word. Therefore, the user can directly determine that the device has been woken up and can have a better experience.

Abstract: A speech recognition method and a speech recognition device are disclosed. The speech recognition method includes: obtaining features of a speech signal to be recognized; performing a path search in a search space generated by establishing a map according to the features to output a decoding result; judging whether a rejection is needed according to the decoding result; and when the rejection is needed, determining that a speech recognition result is the rejection, and when the rejection is not needed, obtaining the speech recognition result according to the decoding result. The method has a good recognition rejection effect.
