The invention relates to computer systems, and more particularly relates to computer systems having a voice-control function.
2. Description of the Related Art
Electronic systems normally have power management, and there are lots of standards of power management, such as the Advanced Configuration and Power Interface (ACPI) specification. The ACPI is a power-management open standard developed by Intel, Microsoft and Toshiba, and is suitable for all classes of computer systems including desktop computers, portable computers, workstations, and server machines. The purpose of the ACPI specification is to efficiently distribute power supply to each component in the computer system. It should be noted that ACPI is a power management interface shared between the software (operating system, OS) and hardware, and power management herein is OS-directed instead of BIOS-directed, which is more beneficial for manufacturers when integrating their standards with each other.
Also, with most computer systems, a user needs to operate them by direct touch. However, it is difficult for a user with disabilities to operate them. The technique of voice recognition has been under development for long time, and today the voice recognition rate is quite high. Therefore, using voice recognition to improve the operability of computer systems for users has become an important issue.
