Aims to promote speech LSI to worldwide market by offering content creation service in English, Chinese and Korean
TOKYO -- Oki Electric Industry Co., Ltd. (TSE: 6703) today unveiled Flexvoice(SM), a data generation service for speech LSIs using text-to-speech (TTS) technology to convert text data into voice data. OKI offers this service in English, Chinese and Korean to promote its Speech Synthesis LSIs for the use in home appliances, electronic devices and household equipment as they become more sophisticated with added values around the world.
“This service responds to the rising needs of voice guidance embedded in household equipment (water heaters, security alarms), home appliances and electronic automotive devices. We’ve seen this trend in Japan, and now in worldwide markets, such as China,” said Hiroshi Enomoto, President of Silicon Solutions Company at OKI. “Through this service, we aim to expand our Speech LSI business outside of Japan as well as expand our product offerings to respond to customer needs in various regions while committing to high-quality sound products.”
OKI’s total services such as arranging narrators, recording, analyzing voice data and editing has been well received for over 20 years. The new TTS service provides an easy turn-key solution for prototyping and design of products in English, Chinese and Korean by generating high quality speech data on a PC. OKI also plans to provide the service in additional languages.
1. Total support to maximize TTS characteristics
OKI provides a website for this service which includes general TTS information such as TTS voice samples, various acoustic sound libraries, speech LSI product lineup, technology information, purchasing of demo board and OKI Speech LSIs. In the Flexvoice(SM) demo board kit, “Speech LSI Utility,” a PC software is enclosed which create voice data format to transport to LSI.
2. Immediate speech data generation
Conventionally, generating speech data took approximately one to two weeks to complete, since studio recording was necessary. However, with this service, users can easily create voice data on a PC, which contributes in shortening the development time. In addition, by flexibly changing expressions and wordings or adding and deleting phrases, users can create various voice data patterns and check them on the demo board. As OKI’s speech LSI is equipped with one time programmable ROM (OTP) or production programmed ROM (P2ROM™), it can respond to production for small lot with various kinds. Users can test the product with the TTS-based voice data for their trial market research and then, shift to using a professional narrators’ voice at the volume production stage.
