Abstract: A method, a device and a terminal for starting a voice input function of a terminal are provided. In some embodiments, the method includes performing a proximity detection; in response to detecting an object is in proximity to the terminal, acquiring a distance between the terminal and the object in proximity to the terminal; if the distance is less than a preset threshold, collecting voice data. The user can start the voice input function of the terminal by only moving the terminal to a position in proximity of his mouth, and speaking to a microphone of the terminal. The method is performed easily and is not likely to be performed incorrectly, which improves the efficiency for starting the voice input function of the terminal.
