Speech synthesis tech pushes voice-based info retrieval

Fujitsu Laboratories Ltd is aiming to push the boundaries of speech synthesis technology by developing a voice-based information retrieval system. The software will enable a smartphone or any other mobile device to read aloud information simply by talking to it.

Most mobile devices are operated by the user through touch and while looking at its display. However, the devices are used in many situations that include walking, driving and workingwhere users must keep their eyes and hands focused on the task. In such scenarios, users can benefit from speech recognition technology that understands human speech and speech synthesis technology where devices are can articulate text. There would be no need for the user to look at or touch the device's display.

Fujitsu Laboratories has claimed to develop industry-leading technologies such as professional-level quality speech synthesis technology, as well as speech recognition technology that can eliminate background noise while picking up on only the user's voice. The company intends to enable new speech interfaces, including the development of data center-based speech recognition and synthesis technologies.

To accomplish this, and in order for the system to accurately pronounce news and other content and correctly recognize words articulated by the user, it must be able to properly support the ever-growing assortment of new terminology, including modern lingo. In addition, the system must be able to properly interpret homonym variants spoken by the user. Fujitsu Laboratories is working to overcome these challenges and to realize a highly original function for smooth and ideal communication.

With this issue at hand, Fujitsu Laboratories has developed a new eyes-free and hands-free speech interface in which, by simply speaking about what the user is interested in, the system pulls up relevant information and reads it out loud. For instance, when the user speaks a particular phrase from a news headline that the system has read, the system will read more detailed articles related to the topic at hand.

The software being developed will tackle linguistic evolution. Fujitsu Laboratories has developed a technology that automatically extracts the orthographic patterns of new terminology from text found on the Internet, and then automatically inputs it into the system's vocabulary dictionary. This makes it possible to create a speech interface that minimizes often misread and falsely recognized words.
