Abstract

An embedded system language teaching device with an ability of pronunciation quality evaluation comprises a hardware platform and a software system. The software system comprises a system program, an arithmetic program and an application program, and operates on a voice processing chip of the hardware platform. The arithmetic program comprises a coder-decoder program of voice and a pronunciation quality evaluation arithmetic program. The idiographic program module comprises audio data play of teaching content, taping, replaying tape, audio speed adjustment and pronunciation quality evaluation. The embedded system language teaching device with the ability of the pronunciation quality evaluation resolves the disadvantages of the prior teaching device, thus not only having the ability to implement the prior teaching device functions such as learning words and sentences, reading, exercise and test and so on, but also integrating the pronunciation quality evaluation function of learners and interactive teaching thought.

Description

Technical field [0001] The invention belongs to the field of speech technology and embedded systems, and particularly relates to an embedded language teaching machine with pronunciation quality evaluation. Background technique [0002] Machine-assisted language learning began to be researched and applied in the 1990s. There are already a variety of embedded English learning machine products on the market, such as OZing and E Percent. They all adopt digital signal processing (Digital Signal Processing, hereinafter referred to as DSP) technology. The hardware system generally includes a microcontroller (Micro Control Unit, hereinafter referred to as MCU) DSP chip, a multimedia digital signal codec (Coder-Decoder, hereinafter referred to as CODEC) flash memory (Flash Memory) Universal Serial Bus, Hereinafter referred to as USB) keyboard and liquid crystal display (Liquid Crystal Display, referred to as LCD), etc.; wherein the MCU is used as the main control chip to execute operating...
