Text-to-speech processor now includes female English language version

26 March 2003 Electronics Technology

Winbond has announced that its WTS701 text-to-speech single chip processor is now being offered in a female English language version (WTS701EF/T). The chip is also available featuring male English and female Mandarin speech.

The WTS701 is claimed to be the industry's first single chip processor that converts text-to-speech (TTS). It creates a more natural, realistic and pleasant sounding speech by converting text to speech using recorded human speech samples. This ensures that the output is a recognisable human voice, unlike computer-generated synthesis solutions, says Winbond.

"In concert with the growing proliferation of text-to-speech technology, we found that a number of applications lend themselves to the use of a female voice, others a male voice," said Hezi Saar, TTS product manager, Winbond America. "By offering both male and female voice capability, manufacturers have more options than ever before for adding text-to-speech functionality to their products."

The chip uses a concatenation algorithm combined with Winbond's proprietary multilevel storage (MLS) technology. It contains two memory arrays; one for the acoustic library and one for the processor program, enabling application-specific customisation for special characters such as SMS icons or chat emoticons.

The company has also announced aggressive new pricing. "The market has reached an inflection point for adopting TTS technology," said Peter Himes, vice president marketing, Winbond America. "Winbond is at the forefront of TTS technology and, as a result, we have experienced a significant increase in design-in interest from all regions and markets. In order to extend our leader-ship role in this technology, and to encourage widespread use of TTS in everyday applications, we have moved the 25K volume quantity price point to $7,00."
