Construction design and application research of embedded digital voice-teaching system

Embedded digital voice-teaching system adopts advanced digital audio processing technology and open architecture, integrates the scientific auxiliary teaching ideas and abundant learning materials, breaks through the characteristics of traditional voice-teaching system which is impersonal and can only be used for teaching, greatly improves the students' learning efficiency. Based on the requirement analysis of digital voice-teaching system, this paper designs the architecture and operation mode of embedded digital voice-teaching system, analyze its practical application value from the perspective of language teaching, language test, remote instruction and so on.
