The present application is used in the technical field of information processing and provides a speech recognition method, a terminal device, and a computer readable storage medium, the speech recognition method comprising: when a preset operation of sending a speech enquiry message to a calling terminal is detected, receiving speech response information returned by the calling terminal on the basis of the speech enquiry information; dividing out text to be adjusted from speech content text corresponding to the speech response information; on the basis of the telephone number of the calling terminal and the content type of the text to be adjusted, determining reference text from a preset database; and, on the basis of the reference text, adjusting the text to be adjusted to obtain target information, thereby improving the degree of accuracy of speech recognition.

TOUCH CONTROL METHOD AND APPARATUS

Embodiments of the present invention relate to the technical field of communications, and provide a touch control method and apparatus, for use in improving the accuracy of an electronic device in false touch prevention. The method comprises: an electronic device obtains a touch event triggered by a user on the touch screen, the touch event comprising the touch position of the touch point; if a target area where the touch position is located is within a first touch area, the electronic device determines whether the touch point is a false touch point, the first touch area being located on the touch screen of the electronic device; if the touch point is a false touch point, the electronic device discards the touch event; if the touch point is not a false touch point, the electronic device reports the touch event.
