Year1995199820012004 Naturalness <3.03.03.84.3 Naturalness is the key label of the synthesized speech. The subjective scoring method is introduced to express the similarity between the human voices and the synthesized voices. MOS Mean Opinion Score 5 is the best 1 is the worst.

Thats a great challenge to the development of Chinese speech technology. –Based on the existing effect that speech technology could achieve, the practical application effect could be improved through customization. But the premise is a thoroughly understanding of the customers need and purpose. iFLYTEK is leading in speech technology market for we are experienced and we have the professional solutions and the splendid team. – iFLYTEK gained the national support for the project of set up the Chinese dialects evaluation and recognition database in 2004.

16. 15 Obstructive factors Customers acceptance to the IT solution needs improvementCustomers acceptance to the IT solution needs improvement Comparing to the developed country, the informatization construction of China is weak and simple. Mostly because the Chinese customers rely more on the hardware rather than the software. Statistic shows that in the oversea countries the ratio of hardware, software and service is 1:2:4, while in china the ratio is less than 4:2:1.Comparing to the developed country, the informatization construction of China is weak and simple. Mostly because the Chinese customers rely more on the hardware rather than the software. Statistic shows that in the oversea countries the ratio of hardware, software and service is 1:2:4, while in china the ratio is less than 4:2:1. –The differed acceptance to software and hardware influence the living condition of Chinese software and service industry. Theres a long time period to overpass until the living condition turns better and everyones concept change. Customers habits need to be cultivate.Customers habits need to be cultivate. –Due to the development of Chinese informatization, telecommunication comes to Chinese residents just a few years; artificial services are the mainstream now. Self-service supported by the speech technology is not so popular as the developed country.

Therere more than 900 such companies in China without unit focus and steering. Thus much energy are spending on the duplicative develop and illicit competition.

Therere more than 900 such companies in China without unit focus and steering. Thus much energy are spending on the duplicative develop and illicit competition. The whole industry is not canonical and ordered yet. –Speech technology are gradually sophisticating, but SI companies still stay at the preliminary stage. Some work like customer needs generation, product design, testing, customization, customers cultivation etc. are in projecting absence. –As the leader of Chinese speech technology, iFLYTEK focused on the basic theories research, practical applications development, customers cultivate, partners training, etc. Now she has been the effective guarantee to the success of speech technology.
