The embodiments of the present invention disclose a speech control circuit and method for electrical equipment, wherein the electrical equipment integrates a speech recognition device. The speech control circuit comprises a detection circuit and a control circuit; the detection circuit is used for sensing a human body in real time, generating sensing information, and generating a speech recognition startup instruction when detecting that the sensing information satisfies a set startup rule; and the control circuit is used for controlling the speech recognition device to be started according to the speech recognition startup instruction. According to the speech control circuit and method for the electrical equipment provided by the embodiments of the present invention, the speech recognition device is only started under the control of the speech control circuit, and is in a turned-off mode or a sleep mode in other time, and therefore, the power consumption of the electrical equipment can be greatly reduced, the speech recognition device can be started automatically and intelligently, interaction efficiency is improved, a speech interaction process is simplified, the problem of false wakeup or false startup caused by the appearance of keywords in the normal conversation of a user can be solved, and the user can be assisted to fast and conveniently control the electrical equipment in a user-friendly manner through speech, and the interactive experience of the user can be improved.
