A new English language training technology implemented on low cost chips is being introduced in Hong Kong at Sensory's 'Designing a Voice User Interface' seminar. Sensory, a leader in embedded speech technologies, is using the language training technology on its RSC-4x family of integrated circuits. These ICs have the ability to support a wide variety of speech technologies on a general purpose 8-bit microcontroller core.
The Chinese government has mandated that all service employees will learn English by the 2008 summer Olympics in Beijing. This has caused a rapidly growing market to emerge for handheld language training devices. Typically, these language trainers use voice chips to play samples of the English phrases and to allow a Chinese speaker to compare his/her recorded voice with that of the English speaker. Sensory says that its new technology goes one step beyond this to perform an analysis of the Chinese speakers' phrases so that the speakers can get immediate feedback on their pronunciation. It is much like an English instructor on a chip.
The way it works is that the technology in the handheld device analyses the phrase's phonemic content, which is compared with that in stored templates. Playback can be sped up or slowed down, and an LED or LCD display can provide feedback on the quality of the spoken phrase during playback in order that the user can visually assess the performance. Settings can be adjusted to switch between a 'lenient,' or a 'tough' instructor.
Sensory's RSC-4x family is supported by a full suite of tools including, assembler, C-Compiler, debugger, and voice coding tools. It plans to bring its language training technology to other embedded platforms, including the ARM line of microcontroller products popular in cellphones. Sensory is seeking strategic partners to roll out English language training handheld products around the world.
