Product overview

Description

X-CUBE-LocalVUI implements local voice recognition user interfaces based on audio capture, and speech recognition. It integrates the Sensory TrulyHandsfree™ (THF) and TrulyNatural™ (TNL) software, and VoiceHub generated vocabulary examples. It also integrates the Picovoice Porcupine and Rhino software, and the Picovoice console generated vocabulary example. The audio capture is based on STM32 peripherals and middleware. It shows how to capture audio from the board microphone through SAI.
The example applications come with default speech recognition models. However, they can be easily updated with a user-specific model. For the Sensory-based examples, the specific model can be defined with the Sensory VoiceHub web tool. For the Picovoice-based example, the specific model can be defined with the Picovoice console web tool.
X-CUBE-LocalVUI provides an implementation on an STM32H747I-DISCO Discovery kit. It can be ported to some other STM32 microcontrollers and boards.
THF, TNL, and VoiceHub are products from Sensory, an authorized STMicroelectronics partner.
Porcupine, Rhino, and Picovoice console are products from Picovoice.
