These products combined provide a fast, cost-effective path to incorporate voice recognition in any type of design for audio products, wearables or any type of connected device. By focusing on local voice recognition, with no network connectivity needed, developers are able to work with quick-actions and phoneme-based modeling for command customization and optimization by model adaptation, just with a small amount of speech data.
The Cyberon CSpotter is a voice trigger and command recognition solution designed to run directly on-device, consuming very low resources and providing high accuracy performance as an alternative voice engine. It runs on Renesas RA 32-bit microcontrollers (MCUs) with 120MHz of speed and enough memory to support multi-language commands as well as H/W crypto engine for strong security.
Cyberon was founded in 2000 and is headquartered in Taipei, Taiwan, focusing on embedded speech recognition solutions, voice to text and text to voice. The Cyberon offline voice recognition algorithm performs real-time control, supporting two languages with voice response - selected from 34 global languages that can be easily integrated. The engine supports customization of voice commands, accepting simple trigger commands, or advanced voice interactions in two languages and offers a friendly tool for command customization, performance tuning and testing.
The Renesas low cost reference design combines the RA MCU, RA6M1, providing a low cost, ultra-low power and high-security function as well as a Flexible Software Package (FSP) to support fast turnaround time in product development. The RA6M1 offers highly integrated capabilities for control/security/graphical and capacitive touch with up to 512KB Flash memory and 256KB SRAM.
In this design, Renesas includes the ISL32743E which is an isolated high-speed RS-485 transceiver, 3.3V half-duplex 40MHz high-speed differential bus transceiver to provide serial communications between the MCU and galvanically isolated high-speed bus to the air conditioning and lighting control board.
The ISL80505 is a high-performance 0.5A LDO that provides power supply to the RA6M1 32-bit MCU and other peripherals on the board. With excellent PSRR over a wide frequency range and programmable output soft-start time, it supports a stable output voltage at ±1.8% VOUT accuracy guaranteed over line, load and very low 45mV dropout voltage at VOUT = 2.5V with very fast transient response.
The PS2561F-1 is an optically coupled UL-approved isolator containing a Gallium Arsenide (GaAs) light-emitting diode and an NPN silicon phototransistor, has high isolation voltage and high current transfer ratio (CTR) to provide isolation for safety requirements of up to 5000Vrms and high-speed switching.
As Renesas also explains, this reference solution, including the Cyberon voice recognition algorithm, was put together to show how easy it is to incorporate voice recognition features into any existing product development project in a fast and cost-effective manner.
