Speech Compression Algorithm for Embedded VUI by Rubidium Ltd.

Product Description

Rubidium provides small footprint solutions as embedded software libraries and APIs that can run on many third party commercial core processors in the market.

When implementing a Voice User Interface in any consumer or industrial device, integrating Rubidium's software decreases time to market, saves PCB space, power use and BOM expense, while covering virtually all speech and voice dialog requirements.

The following speech processing technologies are available as software libraries:

• ASR [Automatic Speech Recognition]
• TTS [Text to Speech]
• Biometric Speaker Verification
• Speech Compression Algorithm

We supply low cost, small footprint solutions by providing code porting, optimization, integration, customization and any other engineering  requirements specific to your microprocessor or hardware platform. Because our licensing model is flexible and can be based on units delivered and Non-Recurring Engineering (NRE), your R&D and manufacturing costs are kept to a minimum.

Unlike companies which rely on third party products, all of Rubidium's technology is developed in-house by a team of experts with years of hands-on scientific and industrial experience. The technology is available as chips or software libraries. This provides our clients with flexibility to select the most effective solution, optimized to fit their current and future speech processing needs.

Rubidium's embedded software is deployed in products produced by some of the world's leading brands. Over 25 million products shipped to the marketplace, from Hong Kong to New York, can attest to the quality of our solutions as well as our clients' success in selecting Rubidium as their supplier.

Rubidium's software solutions were successfully ported to ARM7, ARM9, and other microcontrollers, microprocessors and DSPs. 

Main application features

Speech Compression Algorithm offers storage and playback of pre-recorded speech prompts that can be used to play user instructions, device status indications, alert messages, remaining battery time, entertaining content, memo recordings and any other information.

• Any requirements of pre-recorded voice prompts can be supported to match any set of languages, announcements and voices (even several languages and voices in a single product!)
• High-quality 16KHz wideband speech
• Resource conscious due to powerful low-bit-rate compression, as low as 800 bytes/sec for wideband speech
• Number of prompts in a single product is virtually unlimited
• A large set of prompts is already available in many languages
• For unique prompts, Rubidium provides recording services to support any customer requests
• Voice 'personalities' and celebrity voices can be tailor-made to specific requirements
