Share Article

The Mandarin Voice User Interface offers a unique micro-embedded footprint for mass-market products.

Rubidium saw an opportunity developing, so we took special care to design a product that would respond to the specific needs of the Chinese market.

Rubidium Ltd., a global supplier of embedded speech processing technologies, announced today that it has released a new Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) engine for Mandarin Chinese. Although Rubidium has already implemented Mandarin Voice User Interface (VUI) in the past, the new release marks several key achievements such as:

  •     The seamless integration of ASR, TTS and pre-recorded playback into a single engine
  •     The support of a standard recognition vocabulary
  •     A comprehensive support of the Mandarin character set in both UTF-8 and Unicode
  •     The integration of the new language into its popular multi-lingual software package for Bluetooth®-enabled products based on the CSR Bluecore5™ and CSR8670™ chips

Rubidium has been a recognized innovator in embedded speech processing technology for domestic appliances and consumer applications since 1995, with a global install base exceeding 40 million products. Rubidium's multilingual voice user interface solutions, from low-cost chips and modules to embedded software, include compelling solutions such as TTS, ASR, speech compression and playback (e.g. speech storage, transmission and retrieval) as well as biometric speaker verification.

Although some Mandarin ASR and TTS engines are already available for embedded platforms, Rubidium's release creates a landmark in offering a superior combination of quality and micro-embedded footprint. The slim computational resources (power, MIPS and memory consumption) allow the creation of Chinese speech interfaces in many consumer products such as mobile phones, hands free car-kits, automotive multimedia and infotainment and smart TV.

“The Chinese government has joined many nations around the world in passing legislation that prohibits the use of mobile devices while driving. The new legislation, coupled with China’s growing economy, has created an exceptional potential for utilizing our technology,” states Shlomo Peller, CEO and Founder of Rubidium Ltd. “China-based chip and consumer device manufacturers are capitalizing on the unique opportunities created by our Mandarin release.”

Rubidium has been supplying its voice trigger functionality to the market for over a decade. Mandarin Chinese voice trigger functionality will give truly hands free control to users in China. “Rubidium saw an opportunity developing, so we took special care to design a product that would respond to the specific needs of the Chinese market. This includes voice trigger and in addition, the combined use of Chinese and English," says Peller.
