Sound control network phone device and control method thereof

Abstract

The invention relates to a sound control network phone device and a control method thereof. The device comprises a main control processor, a display screen, a keyboard, communication peripherals, a power supply module, a network switching module, a voice chip, a network interface, voice peripherals, a dynamic RAM and a quick-flash type memory, wherein the main control processor comprises a pulse code modulation memory, a network data access module, a general input output interface, a keyboard controller, a display controller, a quick-flash type memory controller and a dynamic RAM controller, the network interface is a local area network and wide area network interface, the voice peripherals comprise a loudspeaker and a microphone, and the power supply module is used for supplying power for the network phone device. The device is advantaged in that through employing a continuous voice identification module, a special voice searching algorithm, and modeling, identification, decoding and result outputting modes for network phones, voice instructions can be identified according to different scenes, an identification rate is greatly improved, and phone control on people groups and occasions can be realized.

Description

technical field [0001] The invention relates to a network phone, in particular to a voice-activated network phone, which belongs to the technical fields of communication, computer and information. Background technique [0002] Public Switched Telephone Network PSTN (Public Switched Telephone Network) is a circuit switching network based on analog technology, a commonly used old-fashioned telephone system; among many WAN interconnection technologies, the communication cost required for interconnection through PSTN The lowest, but its data transmission quality and transmission speed are also the worst, and the network resource utilization rate of PSTN is also relatively low; PSTN provides an analog dedicated channel, which is connected by several telephone exchanges; when two When a host or router device needs to be connected through the PSTN, a modem (Modem) must be used on the network access side (that is, the user loop side) at both ends to realize the analog / digital and di...

[0002] Public Switched Telephone Network PSTN (Public Switched Telephone Network) is a circuit switching network based on analog technology, a commonly used old-fashioned telephone system; among many WAN interconnection technologies, the communication cost required for interconnection through PSTN The lowest, but its data transmission quality and transmission speed are also the worst, and the network resource utilization rate of PSTN is also relatively low; PSTN provides an analog dedicated channel, which is connected by several telephone exchanges; when two When a host or router device needs to be connected through the PSTN, a modem (Modem) must be used on the network access side (that is, the user loop side) at both ends to realize the analog / digital and digital / analog conversion of the signal; from the perspective of the OSI seven-layer model Look, PSTN can be regarded as a simple extension of the physical layer, and does not provide users with services such as flow control and error control; moreover, since PSTN is a circuit switching method, the entire bandwidth of a path is from establishment to release. It can only be used by the devices at both ends of the path, even if there is no data to be transmitted between them, therefore, this circuit switching method cannot fully utilize the network bandwidth

[0003] In recent years, with the rapid development of science and technology and social economy, Internet phones, as a new type of communication product that replaces traditional PSTN phones, play an increasingly important role in corporate office or personal family life; and Internet phones have many Compared with traditional phones, the functions and settings are more complicated due to the characteristics of accounts and multiple lines; for some people who are inconvenient to use, such as the elderly, the disabled, etc., and in special environments such as dim lights, the complex operations of the phone may be difficult. will hinder the normal use of these people
