Based on the CSSMLs result, iFLYTEK offers the international SSML standard the suggestions of how to improve Chinese.Based on the CSSMLs result, iFLYTEK offers the international SSML standard the suggestions of how to improve Chinese. Following are the latest updated terms for Chinese in the new version of SSML1.1Following are the latest updated terms for Chinese in the new version of SSML1.1 –New sign is defined to support the work of specify the word boundary. –Extend the meaning of special phoneme sign to further support Chinese Pinyins mark up. –Offers a system to define the name. especially for the Chinese name in which some characters would change their pronunciations. –Offers the way to describe dialects. 10

12 11 Keep step forward With 20 years persistent efforts, the speech technology has achieved great progress. Year Naturalness < 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.

13 Obstructive factors in the application of speech technology

14 13 Obstructive factors Artificial services are still the mainstream for the costArtificial services are still the mainstream for the cost China is rich in labor resources, artificial call centers are simple and cheap. So a full-scale speech technology solution is far ahead.China is rich in labor resources, artificial call centers are simple and cheap. So a full-scale speech technology solution is far ahead.

Chinese language is complex, statistic shows therere more than 3000 dialects in China. 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.

17 16 Obstructive factors The actualize capacity need progressThe actualize capacity need progress System Integration corporations (SI) are the main body to develop the application of speech technology in China. 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.System Integration corporations (SI) are the main body to develop the application of speech technology in China. 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.
