Abstract: The present disclosure provides an input method and apparatus, wherein the method comprises: displaying a speech collecting control on a current interface after a word input function is triggered; collecting speech data after the speech collecting control is triggered; upon completion of the speech data collection, converting the collected speech data into words, and displaying the words obtained from the conversion on the screen. In the present disclosure, it is only necessary to display the speech collecting control on the current interface during the whole word input procedure, without popping up the word input method panel that occupies a lot of screen space. The user may input speech after triggering the speech collecting control, thereby achieving automatic conversion and input of words without requiring the user to put in a lot of energy to manually input words. The present disclosure is particularly adapted for application scenarios such as gaming type applications, video type applications and navigation type applications, improves the user's input efficiency and also reduces the input method's impact on the experience of using the original interface.
