VOICECOM is the self-developed speech recognition engine of Voicetune Information Technology Co., Ltd., which supports all kinds of recognition tasks such as tasks related to users or not, tasks with a small or medium size vocabulary. Its’ advantages are small resources, fast and a high recognition rate. It is adapted to the application and development of all kinds of medium lower grade chips and widely used in speech input and inquiry in the PDA, speech dialing of mobile phones and fixed telephone, speech control system for a vehicle and speech data query.
The using of removable module technology when developing VOICECOM makes it supports the needs of different bit streams and applications. Currently 8 to 16bitPCM and GSM6.10 bit stream are supported and also supports modes of keying, monitoring, query and real-time. Query mode in the low-end applications can support up to 1,000 orders in a query task; listening mode can effectively capture the key words and realize non-control input of speech.
